backup battery (with or without RTCC)
- Deep Sleep allows near total power-down, with
the ability to wake-up on internal or external
triggers
- Full RAM and state retention in select Deep Sleep
and VBAT modes
- Sleep and Idle modes selectively shut down
peripherals and/or core for substantial power
reduction and fast wake-up
- Doze mode allows CPU to run at a lower clock
speed than peripherals

Legend: RPn and RPIn represent remappable pins for Peripheral Pin Select (PPS) functions.
Note 1: RD1 is an analog pin and implements the AN35/SEG20/RP24/CN50/RD1 functions. However, there is not an ANSx bit associated with the
RD1 port. Using the RD1 pin for the AN35 function would cause a worst-case increase in device current consumption of 500 ВµA.

DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
• PIC24FJ64GC006
• PIC24FJ128GC006
• PIC24FJ64GC010
• PIC24FJ128GC010
The PIC24FJ128GC010 family expands the capabilities
of the PIC24F family by adding a complete selection of
advanced analog peripherals to its existing digital
features. This combination, along with its ultra
low-power features, Direct Memory Access (DMA) for
peripherals, USB On-The-Go (OTG) and a built-in LCD
controller and driver, makes this family the new
standard for mixed-signal PICВ® microcontrollers in one
economical and power-saving package.
1.1
1.1.1
Aside from these new features, PIC24FJ128GC010
family devices also include all of the legacy power-saving
features of previous PIC24F microcontrollers, such as:
• On-the-Fly Clock Switching, allowing the selection
of a lower power clock during run time
• Doze Mode Operation, for maintaining peripheral
clock speed while slowing the CPU clock
• Instruction-Based Power-Saving modes, for quick
invocation of Idle and the many Sleep modes
1.1.3
Core Features
16-BIT ARCHITECTURE
Central to all PIC24F devices is the 16-bit modified
Harvard architecture, first introduced with Microchip’s
dsPICВ® Digital Signal Controllers (DSCs). The PIC24F
CPU core offers a wide range of enhancements, such as:
• 16-bit data and 24-bit address paths with the
ability to move information between data and
memory spaces
• Linear Addressing of up to 12 Mbytes (program
space) and 32 Kbytes (data)
• A 16-element Working register array with built-in
software stack support
• A 17 x 17 hardware multiplier with support for
integer math
• Hardware support for 32 by 16-bit division
• An instruction set that supports multiple
addressing modes and is optimized for high-level
languages, such as �C’
• Operational performance up to 16 MIPS
1.1.2
Many of these new low-power modes also support the
continuous operation of the low-power, on-chip
Real-Time Clock and Calendar (RTCC), making it
possible for an application to keep time while the
device is otherwise asleep.
XLP POWER-SAVING TECHNOLOGY
The PIC24FJ128GC010 family of devices introduces a
greatly expanded range of power-saving operating
modes for the ultimate in power conservation. The new
modes include:
• Retention Sleep with essential circuits being
powered from a separate low-voltage regulator
• Retention Deep Sleep a lower power mode that
maintains data RAM for fast start-up
• Deep Sleep without RTCC for the lowest possible
power consumption under software control
• VBAT mode (with or without RTCC) to continue
limited operation from a backup battery when VDD
is removed
пѓЈ 2012-2014 Microchip Technology Inc.
OSCILLATOR OPTIONS AND
FEATURES
All of the devices in the PIC24FJ128GC010 family offer
five different oscillator options, allowing users a range
of choices in developing application hardware. These
include:
• Two Crystal modes
• Two External Clock modes
• A Phase-Locked Loop (PLL) frequency multiplier,
which allows clock speeds of up to 32 MHz
• A Fast Internal Oscillator (FRC) – nominal 8 MHz
output, with multiple frequency divider options and
automatic frequency self-calibration during
run time
• A separate Low-Power Internal RC Oscillator
(LPRC) – 31 kHz nominal, for low-power,
timing-insensitive applications.
The internal oscillator block also provides a stable
reference source for the Fail-Safe Clock Monitor
(FSCM). This option constantly monitors the main clock
source against a reference signal provided by the internal oscillator and enables the controller to switch to the
internal oscillator, allowing for continued low-speed
operation or a safe application shutdown.
1.1.4
EASY MIGRATION
Regardless of the memory size, all devices share the
same rich set of peripherals, allowing for a smooth
migration path as applications grow and evolve. This
extends the ability of applications to grow from the
relatively simple, to the powerful and complex, while
still selecting a Microchip device.
DS30009312C-page 13
PIC24FJ128GC010 FAMILY
1.2
Advanced Analog Features
The centerpiece of the PIC24FJ128GC010 family is the
advanced analog block. This feature set provides application developers with all the tools they need for single
chip applications that demand high analog performance.
Included in the advanced analog block are:
• A new 12-bit Pipeline A/D Converter (A/D)
module. A major departure from previous PIC24F
A/D Converters, this module offers up to
50 single-ended input channels (or up to
25 differential channel pairs) and conversion rates
of up to ten million samples per second. It also
provides a wider range of new features that allow
the converter to assess and make decisions on
incoming data without CPU intervention.
• A dual differential channel, Sigma-Delta A/D
Converter, for applications requiring
high-precision conversions (up to 16-bit resolution).
The Sigma-Delta Converter also offers
programmable gain on each channel pair and
user-configurable data rate, between 244 samples
per second and 62.5 ksps.
• Two independent, 10-bit Digital-to-Analog
Converters (DACs), each capable of conversion
rates up to one million samples per second.
• A comparator module with three analog comparators that are configurable for a wide range of
operations. The comparators also have their own
independent, configurable voltage reference.
• A dual operational amplifier module with multiple
input options, selectable power modes, and
rail-to-rail operation on the inputs and outputs.
Each of the op amps can also be configured to
function as a comparator, complete with interrupt
generation.
• A dedicated, integrated band gap voltage reference for all analog modules, providing a range of
on-chip reference voltages and two buffered
reference outputs.
• Flexible multiplexing options for the entire analog
block, allowing for the convenient sharing of
signals between the analog modules.
DS30009312C-page 14
1.3
DMA Controller
PIC24FJ128GC010 family devices also add a Direct
Memory Access (DMA) controller to the existing
PIC24F architecture. The DMA acts in concert with the
CPU, allowing data to move between data memory and
peripherals without the intervention of the CPU,
increasing data throughput, and decreasing execution
time overhead. Six independently programmable channels make it possible to service multiple peripherals at
virtually the same time, with each channel peripheral
performing a different operation. Many types of data
transfer operations are supported.
1.4
USB On-The-Go (OTG)
USB On-The-Go provides on-chip functionality as a
target device compatible with the USB 2.0 standard, as
well as limited stand-alone functionality as a USB
embedded host. By implementing the USB Host Negotiation Protocol (HNP), the module can also dynamically
switch between device and host operation, allowing for
a much wider range of versatile USB-enabled
applications on a microcontroller platform.
PIC24FJ128GC010 family devices also incorporate an
integrated USB transceiver and precision oscillator,
minimizing the required complexity of implementing a
complete USB device, embedded host, dual role or
On-The-Go application.
1.5
LCD Controller
With the PIC24FJ128GC010 family of devices,
Microchip introduces its versatile Liquid Crystal Display
(LCD) controller and driver to the PIC24F family. The
on-chip LCD driver includes many features that make
the integration of displays in low-power applications
easier. These include an integrated voltage regulator
with charge pump and an integrated internal resistor
ladder that allows contrast control in software, and
display operation above device VDD.

Other Special Features
• Peripheral Pin Select (PPS): The Peripheral Pin
Select feature allows most digital peripherals to
be mapped over a fixed set of digital I/O pins.
Users may independently map the input and/or
output of any one of the many digital peripherals
to any one of the I/O pins.
• Communications: The PIC24FJ128GC010
family incorporates several different serial
communication peripherals to handle a range of
application requirements. There are two independent I2Cв„ў modules that support both Master and
Slave modes of operation. Devices also have,
through the PPS feature, four independent UARTs
with built-in IrDAВ® encoders/decoders and two SPI
modules.
• CTMU Interface: In addition to their other analog
features, members of the PIC24FJ128GC010
family include the CTMU interface module. This
provides a convenient method for precision time
measurement and pulse generation, and can
serve as an interface for capacitive sensors.
• Enhanced Parallel Master/Parallel Slave Port:
This module allows rapid and transparent access
to the microcontroller data bus, and enables the
CPU to directly address external data memory. The
parallel port can function in Master or Slave mode,
accommodating data widths of 4, 8 or 16 bits, and
address widths of up to 23 bits in Master modes.
• Real-Time Clock and Calendar (RTCC): This
module implements a full-featured clock and
calendar with alarm functions in hardware, freeing
up timer resources and program memory space
for use of the core application.
• Data Signal Modulator (DSM): The Data Signal
Modulator (DSM) allows the user to mix a digital
data stream (the “modulator signal”) with a carrier
signal to produce a modulated output.

Details on Individual Family
Members
Devices in the PIC24FJ128GC010 family are available
in 64-pin and 100/121-pin packages. The general block
diagram for all devices is shown in Figure 1-1.
The devices are differentiated from each other in
six ways:
1.
2.
3.
4.
5.
6.
Flash program memory (64 Kbytes for
PIC24FJ64GC0XX devices and 128 Kbytes for
PIC24FJ128GC0XX devices).
Available I/O pins and ports (53 pins on 6 ports
for 64-pin devices and 85 pins on 7 ports for
100/121-pin devices).
Available Interrupt-on-Change Notification (ICN)
inputs (52 on 64-pin devices and 82 on
100/121-pin devices).
Available remappable pins (29 pins on 64-pin
devices and 44 pins on 100/121-pin devices).
Maximum available drivable LCD pixels (248 for
64-pin devices and 472 on 100/121-pin devices.)
Analog input channels for the Pipeline A/D
Converter (29 channels for 64-pin devices and
50 channels for 100/121-pin devices).
All other features for devices in this family are identical.
These are summarized in Table 1-1 and Table 1-2.
A list of pin features available on the PIC24FJ128GC010
family devices, sorted by function, is shown in Table 1-3.
Note that this table shows the pin location of individual
peripheral features and not how they are multiplexed on
the same pin. This information is provided in the pinout
diagrams in the beginning of the data sheet. Multiplexed
features are sorted by the priority given to a feature, with
the highest priority peripheral being listed first.

2.2.1
Power Supply Pins
DECOUPLING CAPACITORS
The use of decoupling capacitors on every pair of
power supply pins is required. This includes digital
supply (VDD and VSS) and all analog supplies (AVDD,
SVDD, AVSS and SVSS).
Consider the following criteria when using decoupling
capacitors:
• Value and type of capacitor: A 0.1 F (100 nF),
25V or 50V, X7R dielectric ceramic capacitor is
recommended. The capacitor should be a
low-ESR device with a resonance frequency in
the range of 20 MHz and higher.
• Placement on the printed circuit board: The
decoupling capacitors should be placed as close
to the pins as possible. It is recommended to
place the capacitors on the same side of the
board as the device. If space is constricted, the
capacitor can be placed on another layer on the
PCB using a via; however, ensure that the trace
length from the pin to the capacitor is no greater
than 0.25 inch (6 mm).
• Handling high-frequency noise: If the board is
experiencing high-frequency noise (upward of
tens of MHz), add a second ceramic type capacitor in parallel to the above described decoupling
capacitor. The value of the second capacitor can
be in the range of 0.01 пЃ­F to 0.001 пЃ­F. Place this
second capacitor next to each primary decoupling
capacitor. In high-speed circuit designs, consider
implementing a pair of capacitances as close to
the power and ground pins as possible
(e.g., 0.1 пЃ­F in parallel with 0.001 пЃ­F).
• Maximizing performance: On the board layout
from the power supply circuit, run the power and
return traces to the decoupling capacitors first,
and then to the device pins. This ensures that the
decoupling capacitors are first in the power chain.
Equally important is to keep the trace length
between the capacitor and the power pins to a
minimum, thereby reducing PCB trace
inductance.
2.2.2
BULK CAPACITORS
On boards with power traces running longer than
six inches in length, it is suggested to use a tank capacitor for integrated circuits including microcontrollers to
supply a local power source. The value of the tank
capacitor should be determined based on the trace
resistance that connects the power supply source to
the device, and the maximum current drawn by the
device in the application. In other words, select the tank
capacitor so that it meets the acceptable voltage sag at
the device. Typical values range from 4.7 пЃ­F to 47 пЃ­F.
DS30009312C-page 34
2.3
Master Clear (MCLR) Pin
The MCLR pin provides two specific device functions:
device Reset, and device programming and debugging. If programming and debugging are not required
in the end application, a direct connection to VDD may
be all that is required. The addition of other components, to help increase the application’s resistance to
spurious Resets from voltage sags, may be beneficial.
A typical configuration is shown in Figure 2-1. Other
circuit designs may be implemented, depending on the
application’s requirements.
During programming and debugging, the resistance
and capacitance that can be added to the pin must
be considered. Device programmers and debuggers
drive the MCLR pin. Consequently, specific voltage
levels (VIH and VIL) and fast signal transitions must
not be adversely affected. Therefore, specific values
of R1 and C1 will need to be adjusted based on the
application and PCB requirements. For example, it is
recommended that the capacitor, C1, be isolated
from the MCLR pin during programming and debugging operations by using a jumper (Figure 2-2). The
jumper is replaced for normal run-time operations.
Any components associated with the MCLR pin
should be placed within 0.25 inch (6 mm) of the pin.

CONSIDERATIONS FOR CERAMIC
CAPACITORS
In recent years, large value, low-voltage, surface-mount
ceramic capacitors have become very cost effective in
sizes up to a few tens of microfarad. The low-ESR, small
physical size and other properties make ceramic
capacitors very attractive in many types of applications.
Ceramic capacitors are suitable for use with the internal voltage regulator of this microcontroller. However,
some care is needed in selecting the capacitor to
ensure that it maintains sufficient capacitance over the
intended operating range of the application.
Typical low-cost, 10 пЃ­F ceramic capacitors are available
in X5R, X7R and Y5V dielectric ratings (other types are
also available, but are less common). The initial tolerance specifications for these types of capacitors are
often specified as В±10% to В±20% (X5R and X7R) or
-20%/+80% (Y5V). However, the effective capacitance
that these capacitors provide in an application circuit will
also vary based on additional factors, such as the
applied DC bias voltage and the temperature. The total
in-circuit tolerance is, therefore, much wider than the
initial tolerance specification.
The X5R and X7R capacitors typically exhibit satisfactory temperature stability (ex: В±15% over a wide
temperature range, but consult the manufacturer’s data
sheets for exact specifications). However, Y5V capacitors typically have extreme temperature tolerance
specifications of +22%/-82%. Due to the extreme
temperature tolerance, a 10 пЃ­F nominal rated Y5V type
capacitor may not deliver enough total capacitance to
meet minimum internal voltage regulator stability and
transient response requirements. Therefore, Y5V
capacitors are not recommended for use with the
internal regulator.
In addition to temperature tolerance, the effective
capacitance of large value ceramic capacitors can vary
substantially, based on the amount of DC voltage
applied to the capacitor. This effect can be very significant, but is often overlooked or is not always
documented.
Typical DC bias voltage vs. capacitance graph for X7R
type capacitors is shown in Figure 2-4.

DC Bias Voltage (VDC)
When selecting a ceramic capacitor to be used with the
internal voltage regulator, it is suggested to select a
high-voltage rating, so that the operating voltage is a
small percentage of the maximum rated capacitor
voltage. The minimum DC rating for the ceramic
capacitor on VCAP is 16V. Suggested capacitors are
shown in Table 2-1.
2.5
ICSP Pins
The PGECx and PGEDx pins are used for In-Circuit
Serial Programming (ICSP) and debugging purposes.
It is recommended to keep the trace length between
the ICSP connector and the ICSP pins on the device as
short as possible. If the ICSP connector is expected to
experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of
ohms, not to exceed 100Ω.
Pull-up resistors, series diodes and capacitors on the
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communications to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective
device Flash programming specification for information
on capacitive loading limits and pin Voltage Input High
(VIH) and Voltage Input Low (VIL) requirements.
For device emulation, ensure that the “Communication
Channel Select” (i.e., PGECx/PGEDx pins), programmed
into the device, matches the physical connections for the
ICSP to the Microchip debugger/emulator tool.
The MCLR connection from the ICSP header should connect directly to the MCLR pin on the device. A capacitor to
ground (C1 in Figure 2-2) is optional, but if used, may
interfere with ICSP operation if the value exceeds 0.01 пЃ­F.
In most cases, this capacitor is not required.
For more information on available Microchip
development tools connection requirements, refer to
Section 35.0 “Development Support”.

External Oscillator Pins
FIGURE 2-5:
Many microcontrollers have options for at least two
oscillators: a high-frequency primary oscillator and a
low-frequency secondary oscillator (refer to Section 9.0
“Oscillator Configuration” for details).
The oscillator circuit should be placed on the same
side of the board as the device. Place the oscillator
circuit close to the respective oscillator pins with no
more than 0.5 inch (12 mm) between the circuit
components and the pins. The load capacitors should
be placed next to the oscillator itself, on the same side
of the board.
Use a grounded copper pour around the oscillator
circuit to isolate it from surrounding circuits. The
grounded copper pour should be routed directly to the
MCU ground. Do not run any signal traces or power
traces inside the ground pour. Also, if using a two-sided
board, avoid any traces on the other side of the board
where the crystal is placed.
Layout suggestions are shown in Figure 2-5. In-line
packages may be handled with a single-sided layout
that completely encompasses the oscillator pins. With
fine-pitch packages, it is not always possible to completely surround the pins and components. A suitable
solution is to tie the broken guard sections to a mirrored
ground layer. In all cases, the guard trace(s) must be
returned to ground.
In planning the application’s routing and I/O assignments, ensure that adjacent port pins, and other
signals in close proximity to the oscillator, are benign
(i.e., free of high frequencies, short rise and fall times
and other similar noise).

oscillator circuits, please refer to these Microchip

Configuration of Analog and
Digital Pins During ICSP
Operations
If an ICSP compliant emulator is selected as a debugger, it automatically initializes all of the A/D input pins
(ANx) as “digital” pins. Depending on the particular
device, this is done by setting all bits in the ADxPCFG
register(s) or clearing all bits in the ANSx registers.
All PIC24F devices will have either one or more
ADxPCFG registers or several ANSx registers (one for
each port); no device will have both. Refer to
Section 11.2 “Configuring Analog Port Pins
(ANSx)” for more specific information.
The bits in these registers that correspond to the A/D
pins that initialized the emulator must not be
changed by the user application firmware; otherwise,
communication errors will result between the debugger
and the device.
If your application needs to use certain A/D pins as
analog input pins during the debug session, the user
application must modify the appropriate bits during
initialization of the A/D module, as follows:
• For devices with an ADxPCFG register, clear the
bits corresponding to the pin(s) to be configured
as analog. Do not change any other bits, particularly those corresponding to the PGECx/PGEDx
pair, at any time.
• For devices with ANSx registers, set the bits
corresponding to the pin(s) to be configured as
analog. Do not change any other bits, particularly
those corresponding to the PGECx/PGEDx pair,
at any time.
When a Microchip debugger/emulator is used as a
programmer, the user application firmware must
correctly configure the ADxPCFG or ANSx registers.
Automatic initialization of these registers is only done
during debugger operation. Failure to correctly configure
the register(s) will result in all A/D pins being recognized
as analog input pins, resulting in the port value being
read as a logic �0’, which may affect user application
functionality.
DS30009312C-page 38

Sigma-Delta A/D Connections
The Sigma-Delta A/D Converter has input and power
connections that are independent from the rest of the
microcontroller. These connections are required to use
the converter, and are in addition to the connection and
layout connections provided in Section 2.1 “Basic
Connection Requirements” and Section 2.2 “Power
Supply Pins”.
2.8.1
VOLTAGE AND GROUND
CONNECTIONS
To minimize noise interference, the Sigma-Delta A/D
Converter has independent voltage pins. Converter circuits are supplied through the SVDD pin. Independent
ground return is provided through the SVSS pin.
As with the microcontroller’s VDD/VSS and AVDD/AVSS
pins, bypass capacitors are required on SVDD and SVSS.
Requirements for these capacitors are identical to those
for the VDD/VSS and AVDD/AVSS pins.
It is recommended that designs using the Sigma-Delta
A/D Converter incorporate a separate ground return
path for analog circuits. The analog and digital grounds
may be tied to a single point at the power source.
Analog pins that require grounding should be tied to
this analog return. SVSS can be tied to the digital
ground, along with VSS and AVSS.
2.8.2
ANALOG INPUTS
The analog signals to be converted are connected to the
pins of CH0 and/or CH1. Each channel has inverting and
non-inverting inputs (CHx- and CHx+, respectively), and
is fully differential.
If not used for conversion, CH1+ and CH1- can be used
to supply an external voltage reference to the converter. If an external reference is not used and CH1 is
not needed as a conversion input, both pins should be
connected to the analog ground return.
2.9
Unused I/Os
Unused I/O pins should be configured as outputs and
driven to a logic low state. Alternatively, connect a 1 kΩ
to 10 kΩ resistor to VSS on unused pins and drive the
output to logic low.

Note:
CPU
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “CPU with Extended Data Space
(EDS)” (DS39732). The information in this
data sheet supersedes the information in
the FRM.
The PIC24F CPU has a 16-bit (data) modified, Harvard
architecture with an enhanced instruction set and a
24-bit instruction word with a variable length opcode
field. The Program Counter (PC) is 23 bits wide and
addresses up to 4M instructions of user program
memory space. A single-cycle instruction prefetch
mechanism is used to help maintain throughput and
provides predictable execution. All instructions execute
in a single cycle, with the exception of instructions that
change the program flow, the double-word move
(MOV.D) instruction and the table instructions.
Overhead-free program loop constructs are supported
using the REPEAT instructions, which are interruptible
at any point.
PIC24F devices have sixteen, 16-bit Working registers
in the programmer’s model. Each of the Working
registers can act as a data, address or address offset
register. The 16th Working register (W15) operates as
a Software Stack Pointer for interrupts and calls.
The lower 32 Kbytes of the Data Space (DS) can be
accessed linearly. The upper 32 Kbytes of the Data
Space are referred to as Extended Data Space to which
the extended data RAM, EPMP memory space or
program memory can be mapped.
The Instruction Set Architecture (ISA) has been
significantly enhanced beyond that of the PIC18, but
maintains an acceptable level of backward compatibility. All PIC18 instructions and addressing modes are
supported, either directly, or through simple macros.
Many of the ISA enhancements have been driven by
compiler efficiency needs.
пѓЈ 2012-2014 Microchip Technology Inc.
The core supports Inherent (no operand), Relative,
Literal and Memory Direct Addressing modes, along
with three groups of addressing modes. All modes support Register Direct and various Register Indirect
modes. Each group offers up to seven addressing
modes. Instructions are associated with predefined
addressing modes, depending upon their functional
requirements.
For most instructions, the core is capable of executing
a data (or program data) memory read, a Working register (data) read, a data memory write and a program
(instruction) memory read per instruction cycle. As a
result, three parameter instructions can be supported,
allowing trinary operations (that is, A + B = C) to be
executed in a single cycle.
A high-speed, 17-bit x 17-bit multiplier has been
included to significantly enhance the core arithmetic
capability and throughput. The multiplier supports
Signed, Unsigned and Mixed mode, 16-bit x 16-bit or
8-bit x 8-bit, integer multiplication. All multiply
instructions execute in a single cycle.
The 16-bit ALU has been enhanced with integer divide
assist hardware that supports an iterative non-restoring
divide algorithm. It operates in conjunction with the
REPEAT instruction looping mechanism and a selection
of iterative divide instructions to support 32-bit (or
16-bit), divided by 16-bit, integer signed and unsigned
division. All divide operations require 19 cycles to
complete but are interruptible at any cycle boundary.
The PIC24F has a vectored exception scheme, with up to
8 sources of non-maskable traps and up to 118 interrupt
sources. Each interrupt source can be assigned to one of
seven priority levels.
A block diagram of the CPU is shown in Figure 3-1.
3.1
Programmer’s Model
The programmer’s model for the PIC24F is shown in
Figure 3-2. All registers in the programmer’s model are
memory-mapped and can be manipulated directly by
instructions. A description of each register is provided
in Table 3-1. All registers associated with the
programmer’s model are memory-mapped.

3.3
Arithmetic Logic Unit (ALU)
The PIC24F ALU is 16 bits wide and is capable of addition, subtraction, bit shifts and logic operations. Unless
otherwise mentioned, arithmetic operations are 2’s
complement in nature. Depending on the operation, the
ALU may affect the values of the Carry (C), Zero (Z),
Negative (N), Overflow (OV) and Digit Carry (DC)
Status bits in the SR register. The C and DC Status bits
operate as Borrow and Digit Borrow bits, respectively,
for subtraction operations.
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array, or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.
The PIC24F CPU incorporates hardware support for
both multiplication and division. This includes a
dedicated hardware multiplier and support hardware
for 16-bit divisor division.
3.3.1
MULTIPLIER
The ALU contains a high-speed, 17-bit x 17-bit
multiplier. It supports unsigned, signed or mixed sign
operation in several multiplication modes:
1.
2.
3.
4.
5.
6.
7.
16-bit x 16-bit signed
16-bit x 16-bit unsigned
16-bit signed x 5-bit (literal) unsigned
16-bit unsigned x 16-bit unsigned
16-bit unsigned x 5-bit (literal) unsigned
16-bit unsigned x 16-bit signed
8-bit unsigned x 8-bit unsigned
TABLE 3-2:
3.3.2
DIVIDER
The divide block supports signed and unsigned integer
divide operations with the following data sizes:
1.
2.
3.
4.
32-bit signed/16-bit signed divide
32-bit unsigned/16-bit unsigned divide
16-bit signed/16-bit signed divide
16-bit unsigned/16-bit unsigned divide
The quotient for all divide instructions ends up in W0
and the remainder in W1. Sixteen-bit signed and
unsigned DIV instructions can specify any W register
for both the 16-bit divisor (Wn), and any W register
(aligned) pair (W(m + 1):Wm) for the 32-bit dividend.
The divide algorithm takes one cycle per bit of divisor,
so both 32-bit/16-bit and 16-bit/16-bit instructions take
the same number of cycles to execute.
3.3.3
MULTIBIT SHIFT SUPPORT
The PIC24F ALU supports both single bit and
single-cycle, multibit arithmetic and logic shifts. Multibit
shifts are implemented using a shifter block, capable of
performing up to a 15-bit arithmetic right shift, or up to
a 15-bit left shift, in a single cycle. All multibit shift
instructions only support Register Direct Addressing for
both the operand source and result destination.
A full summary of instructions that use the shift
operation is provided in Table 3-2.

MEMORY ORGANIZATION
As Harvard architecture devices, PIC24F microcontrollers feature separate program and data memory
spaces and buses. This architecture also allows direct
access of program memory from the Data Space (DS)
during code execution.
4.1
Program Memory Space
The program address memory space of the
PIC24FJ128GC010 family devices is 4M instructions.
The space is addressable by a 24-bit value derived
FIGURE 4-1:
User access to the program memory space is restricted
to the lower half of the address range (000000h to
7FFFFFh). The exception is the use of TBLRD/TBLWT
operations, which use TBLPAG<7> to permit access to
the Configuration bits and Device ID sections of the
configuration memory space.
Memory maps for the PIC24FJ128GC010 family of

PROGRAM MEMORY
ORGANIZATION
4.1.3
In PIC24FJ128GC010 family devices, the top four words
of on-chip program memory are reserved for configuration information. On device Reset, the configuration
information is copied into the appropriate Configuration
register. The addresses of the Flash Configuration Word
for devices in the PIC24FJ128GC010 family are shown
in Table 4-1. Their location in the memory map is shown
with the other memory vectors in Figure 4-1.
The program memory space is organized in
word-addressable blocks. Although it is treated as
24 bits wide, it is more appropriate to think of each
address of the program memory as a lower and upper
word, with the upper byte of the upper word being
unimplemented. The lower word always has an even
address, while the upper word has an odd address
(Figure 4-2).
The Configuration Words in program memory are a
compact format. The actual Configuration bits are
mapped in several different registers in the configuration
memory space. Their order in the Flash Configuration
Words does not reflect a corresponding arrangement in
the configuration space. Additional details on the device
Configuration Words are provided in Section 34.0
“Special Features”.
Program memory addresses are always word-aligned
on the lower word and addresses are incremented or
decremented by two during code execution. This
arrangement also provides compatibility with data
memory space addressing and makes it possible to
access data in the program memory space.
4.1.2

Note:
The upper half of data memory address space (8000h to
FFFFh) is used as a window into the Extended Data
Space (EDS). This allows the microcontroller to directly
access a greater range of data beyond the standard
16-bit address range. EDS is discussed in detail in
Section 4.2.5 “Extended Data Space (EDS)”.
Data Memory Space
This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive reference source. For more information, refer
to the “dsPIC33/PIC24 Family Reference
Manual”, “Data Memory with Extended
Data Space (EDS)” (DS39733). The
information in this data sheet supersedes
the information in the FRM.
The lower half of DS is compatible with previous PIC24F
microcontrollers without EDS. All PIC24FJ128GC010
family devices implement 8 Kbytes of data RAM in the
lower half of the DS, from 0800h to 27FFh.
4.2.1
The PIC24F core has a 16-bit wide data memory space,
addressable as a single linear range. The Data Space
(DS) is accessed using two Address Generation Units
(AGUs), one each for read and write operations. The
Data Space memory map is shown in Figure 4-3.
The 16-bit wide data addresses in the data memory
space point to bytes within the Data Space. This gives a
DS address range of 64 Kbytes or 32K words. The lower
half (0000h to 7FFFh) is used for implemented (on-chip)
memory addresses.
FIGURE 4-3:
The data memory space is organized in
byte-addressable, 16-bit wide blocks. Data is aligned in
data memory and registers as 16-bit words, but all Data
Space Effective Addresses (EAs) resolve to bytes. The
Least Significant Bytes (LSBs) of each word have even
addresses, while the Most Significant Bytes (MSBs)
have odd addresses.

4.2.2
DATA MEMORY ORGANIZATION
AND ALIGNMENT
A Sign-Extend (SE) instruction is provided to allow users
to translate 8-bit signed data to 16-bit signed values.
Alternatively, for 16-bit unsigned data, users can clear
the MSB of any W register by executing a Zero-Extend
(ZE) instruction on the appropriate address.
To maintain backward compatibility with PICВ® MCUs and
improve Data Space memory usage efficiency, the
PIC24F instruction set supports both word and byte
operations. As a consequence of byte accessibility, all
EA calculations are internally scaled to step through
word-aligned memory. For example, the core recognizes
that Post-Modified Register Indirect Addressing mode
[Ws++] will result in a value of Ws + 1 for byte operations
and Ws + 2 for word operations.
Although most instructions are capable of operating on
word or byte data sizes, it should be noted that some
instructions operate only on words.
4.2.3
The 8-Kbyte area between 0000h and 1FFFh is
referred to as the Near Data Space. Locations in this
space are directly addressable via a 13-bit absolute
address field within all memory direct instructions. The
remainder of the Data Space is addressable indirectly.
Additionally, the whole Data Space is addressable
using MOV instructions, which support Memory Direct
Addressing with a 16-bit address field.
Data byte reads will read the complete word, which
contains the byte, using the LSB of any EA to determine which byte to select. The selected byte is placed
onto the LSB of the data path. That is, data memory
and registers are organized as two parallel, byte-wide
entities with shared (word) address decode but
separate write lines. Data byte writes only write to the
corresponding side of the array or register which
matches the byte address.
4.2.4
All word accesses must be aligned to an even address.
Misaligned word data fetches are not supported, so
care must be taken when mixing byte and word
operations or translating from 8-bit MCU code. If a
misaligned read or write is attempted, an address error
trap will be generated. If the error occurred on a read,
the instruction underway is completed; if it occurred on
a write, the instruction will be executed but the write will
not occur. In either case, a trap is then executed, allowing the system and/or user to examine the machine
state prior to execution of the address Fault.
SPECIAL FUNCTION REGISTER
(SFR) SPACE
The first 2 Kbytes of the Near Data Space, from 0000h
to 07FFh, are primarily occupied with Special Function
Registers (SFRs). These are used by the PIC24F core
and peripheral modules for controlling the operation of
the device.
SFRs are distributed among the modules that they control and are generally grouped together by module. Much
of the SFR space contains unused addresses; these are
read as �0’. A diagram of the SFR space, showing where
the SFRs are actually implemented, is shown in
Table 4-2. Each implemented area indicates a 32-byte
region where at least one address is implemented as an
SFR. A complete list of implemented SFRs, including
their addresses, is shown in Tables 4-3 through 4-39.
All byte loads into any W register are loaded into the
LSB. The Most Significant Byte (MSB) is not modified.

EXTENDED DATA SPACE (EDS)
The Extended Data Space (EDS) allows PIC24F
devices to address a much larger range of data than
would otherwise be possible with a 16-bit address
range. EDS includes any additional internal data memory not directly accessible by the lower 32-Kbyte data
address space and any external memory through the
Enhanced Parallel Master Port (EPMP).
In addition, EDS also allows read access to the
program memory space. This feature is called Program
Space Visibility (PSV) and is discussed in detail in
Section 4.3.3 “Reading Data from Program Memory
Using EDS”.
Figure 4-4 displays the entire EDS space. The EDS is
organized as pages, called EDS pages, with one page
equal to the size of the EDS window (32 Kbytes). A
particular EDS page is selected through the Data
Space Read register (DSRPAG) or Data Space Write
register (DSWPAG). For PSV, only the DSRPAG register is used. The combination of the DSRPAG register
value and the 16-bit wide data address forms a 24-bit
Effective Address (EA).
FIGURE 4-4:
Special
Function
Registers
The data addressing range of PIC24FJ128GC010 family
devices depends on the version of the Enhanced
Parallel Master Port (EPMP) implemented on a particular device; this is, in turn, a function of the device pin
count. Table 4-40 lists the total memory accessible
by each of the devices in this family. For more details
on accessing external memory using EPMP, refer to
the “dsPIC33/PIC24 Family Reference Manual”,
“Enhanced Parallel Master Port (EPMP)” (DS39730).

Data Read from EDS
In order to read the data from the EDS space, first, an
Address Pointer is set up by loading the required EDS
page number into the DSRPAG register and assigning
the offset address to one of the W registers. Once the
above assignment is done, the EDS window is enabled
by setting bit 15 of the Working register, assigned with
the offset address; then, the contents of the pointed
EDS location can be read.
Example 4-1 shows how to read a byte, word and
double-word from EDS.
Note:
Figure 4-5 illustrates how the EDS space address is
generated for read operations.
All read operations from EDS space have
an overhead of one instruction cycle.
Therefore, a minimum of two instruction
cycles is required to complete an EDS
read. EDS reads under the REPEAT
instruction: the first two accesses take
three cycles and the subsequent
accesses take one cycle.
When the Most Significant bit (MSb) of EA is �1’ and
DSRPAG<9> = 0, the lower 9 bits of DSRPAG are concatenated to the lower 15 bits of the EA to form a 24-bit
EDS space address for read operations.

Data Write into EDS
In order to write data to EDS space, such as in EDS
reads, an Address Pointer is set up by loading the
required EDS page number into the DSWPAG register
and assigning the offset address to one of the W registers. Once the above assignment is done, then the
EDS window is enabled by setting bit 15 of the Working
register, assigned with the offset address, and the
accessed location can be written.
0x8000. While developing code in assembly, care must
be taken to update the Data Space Page registers when
an Address Pointer crosses the page boundary. The �C’
compiler keeps track of the addressing, and increments
or decrements the Page registers accordingly, while
accessing contiguous data memory locations.
Note 1: All write operations to EDS are executed
in a single cycle.
2: Use of Read/Modify/Write operation on
any EDS location under a REPEAT
instruction is not supported. For example,
BCLR, BSW, BTG, RLC f, RLNC f, RRC f,
RRNC f, ADD f, SUB f, SUBR f, AND f,
IOR f, XOR f, ASR f, ASL f.
Figure 4-6 illustrates how the EDS space address is
generated for write operations.
When the MSb of EA is �1’, the lower 9 bits of DSWPAG
are concatenated to the lower 15 bits of EA to form a
24-bit EDS address for write operations. Example 4-2
shows how to write a byte, word and double-word to
EDS.
3: Use the DSRPAG register while
performing Read/Modify/Write operations.
The Data Space Page registers (DSRPAG/DSWPAG)
do not update automatically while crossing a page
boundary when the rollover happens from 0xFFFF to

Address Error Trap(3)
If the source/destination address is below 8000h, the DSRPAG and DSWPAG registers are not considered.
This Data Space can also be accessed by Direct Addressing.
When the source/destination address is above 8000h and DSRPAG/DSWPAG are �0’, an address error
trap will occur.
SOFTWARE STACK
Apart from its use as a Working register, the W15
register in PIC24F devices is also used as a Software
Stack Pointer (SSP). The pointer always points to the
first available free word and grows from lower to higher
addresses. It predecrements for stack pops and postincrements for stack pushes, as shown in Figure 4-7.
Note that for a PC push during any CALL instruction,
the MSB of the PC is zero-extended before the push,
ensuring that the MSB is always clear.
Note:
Comment
Near Data Space(2)
Invalid Address
A PC push during exception processing
will concatenate the SR register to the
MSB of the PC prior to the push.
The Stack Pointer Limit Value register (SPLIM), associated with the Stack Pointer, sets an upper address
boundary for the stack. SPLIM is uninitialized at Reset.
As is the case for the Software Stack Pointer,
SPLIM<0> is forced to �0’ as all stack operations must
be word-aligned. Whenever an EA is generated using
W15 as a source or destination pointer, the resulting
address is compared with the value in SPLIM. If the
contents of the Stack Pointer (W15) and the SPLIM register are equal, and a push operation is performed, a
stack error trap will not occur. The stack error trap will
occur on a subsequent push operation. Thus, for
пѓЈ 2012-2014 Microchip Technology Inc.
example, if it is desirable to cause a stack error trap
when the stack grows beyond address, 2000h in RAM,
initialize the SPLIM with the value, 1FFEh.
Similarly, a Software Stack Pointer underflow (stack
error) trap is generated when the Stack Pointer address
is found to be less than 0800h. This prevents the stack
from interfering with the SFR space.
A write to the SPLIM register should not be immediately
followed by an indirect read operation using W15.

4.3.1
Interfacing Program and Data
Memory Spaces
ADDRESSING PROGRAM SPACE
Since the address ranges for the data and program
spaces are 16 and 24 bits, respectively, a method is
needed to create a 23-bit or 24-bit program address
from 16-bit data registers. The solution depends on the
interface method to be used.
The PIC24F architecture uses a 24-bit wide program
space and 16-bit wide Data Space. The architecture is
also a modified Harvard scheme, meaning that data
can also be present in the program space. To use this
data successfully, it must be accessed in a way that
preserves the alignment of information in both spaces.
For table operations, the 8-bit Table Memory Page
Address register (TBLPAG) is used to define a 32K word
region within the program space. This is concatenated
with a 16-bit EA to arrive at a full 24-bit program space
address. In this format, the MSBs of TBLPAG are
used to determine if the operation occurs in the user
memory (TBLPAG<7> = 0) or the configuration memory
(TBLPAG<7> = 1).
Aside from normal execution, the PIC24F architecture
provides two methods by which program space can be
accessed during operation:
• Using table instructions to access individual bytes
or words anywhere in the program space
• Remapping a portion of the program space into
the Data Space (Program Space Visibility)
For remapping operations, the 10-bit Extended Data
Space Read register (DSRPAG) is used to define a
16K word page in the program space. When the Most
Significant bit (MSb) of the EA is �1’, and the MSb (bit 9)
of DSRPAG is �1’, the lower 8 bits of DSRPAG are concatenated with the lower 15 bits of the EA to form a
23-bit program space address. The DSRPAG<8> bit
decides whether the lower word (when the bit is �0’) or
the higher word (when the bit is �1’) of program memory
is mapped. Unlike table operations, this strictly limits
remapping operations to the user memory area.
Table instructions allow an application to read or write
to small areas of the program memory. This makes the
method ideal for accessing data tables that need to be
updated from time to time. It also allows access to all
bytes of the program word. The remapping method
allows an application to access a large block of data on
a read-only basis, which is ideal for look-ups from a
large table of static data. It can only access the least
significant word of the program word.
Table 4-42 and Figure 4-8 show how the program EA is
created for table operations, and remapping accesses
from the data EA. Here, P<23:0> refer to a program
space word, whereas D<15:0> refer to a Data Space
word.

DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
The TBLRDL and TBLWTL instructions offer a direct
method of reading or writing the lower word of any
address within the program space without going through
Data Space. The TBLRDH and TBLWTH instructions are
the only method to read or write the upper 8 bits of a
program space word as data.
The PC is incremented by two for each successive
24-bit program word. This allows program memory
addresses to directly map to Data Space addresses.
Program memory can thus be regarded as two, 16-bit
word-wide address spaces, residing side by side, each
with the same address range. TBLRDL and TBLWTL
access the space which contains the least significant
data word, and TBLRDH and TBLWTH access the space
which contains the upper data byte.
Two table instructions are provided to move byte or
word-sized (16-bit) data to and from program space.
Both function as either byte or word operations.
1.
TBLRDL (Table Read Low): In Word mode, it
maps the lower word of the program space
location (P<15:0>) to a data address (D<15:0>).
In Byte mode, either the upper or lower byte of
the lower program word is mapped to the lower
byte of a data address. The upper byte is
selected when byte select is �1’; the lower byte
is selected when it is �0’.
FIGURE 4-9:
2.
TBLRDH (Table Read High): In Word mode, it
maps the entire upper word of a program address
(P<23:16>) to a data address. Note that
D<15:8>, the �phantom’ byte, will always be �0’.
In Byte mode, it maps the upper or lower byte of
the program word to D<7:0> of the data
address, as above. Note that the data will
always be �0’ when the upper �phantom’ byte is
selected (Byte Select = 1).
In a similar fashion, two table instructions, TBLWTH
and TBLWTL, are used to write individual bytes or
words to a program space address. The details of
their operation are described in Section 6.0 “Flash
Program Memory”.
For all table operations, the area of program memory
space to be accessed is determined by the Table
Memory Page Address register (TBLPAG). TBLPAG
covers the entire program memory space of the
device, including user and configuration spaces. When
TBLPAG<7> = 0, the table page is located in the user
memory space. When TBLPAG<7> = 1, the page is
located in configuration space.
Note:
Only Table Read operations will execute
in the configuration memory space where
Device IDs are located. Table Write
operations are not allowed.

READING DATA FROM PROGRAM
MEMORY USING EDS
The upper 32 Kbytes of Data Space may optionally be
mapped into any 16K word page of the program space.
This provides transparent access of stored constant
data from the Data Space without the need to use
special instructions (i.e., TBLRDL/H).
Program space access through the Data Space occurs
when the MSb of EA is �1’ and the DSRPAG<9> is also
�1’. The lower 8 bits of DSRPAG are concatenated to the
Wn<14:0> bits to form a 23-bit EA to access program
memory. The DSRPAG<8> bit decides which word
should be addressed; when the bit is �0’, the lower word
and when �1’, the upper word of the program memory is
accessed.
The entire program memory is divided into 512 EDS
pages, from 200h to 3FFh, each consisting of 16K words
of data. Pages, 200h to 2FFh, correspond to the lower
words of the program memory, while 300h to 3FFh
correspond to the upper words of the program memory.
Using this EDS technique, the entire program memory
can be accessed. Previously, the access to the upper
word of the program memory was not supported.

For operations that use PSV and are executed outside
a REPEAT loop, the MOV and MOV.D instructions will
require one instruction cycle in addition to the specified
execution time. All other instructions will require two
instruction cycles in addition to the specified execution
time.
For operations that use PSV, which are executed inside
a REPEAT loop, there will be some instances that
require two instruction cycles in addition to the
specified execution time of the instruction:
• Execution in the first iteration
• Execution in the last iteration
• Execution prior to exiting the loop due to an
interrupt
• Execution upon re-entering the loop after an
interrupt is serviced
Any other iteration of the REPEAT loop will allow the
instruction accessing data, using PSV, to execute in a
single cycle.

DIRECT MEMORY ACCESS
CONTROLLER (DMA)
This data sheet summarizes the features of
the PIC24FJ128GC010 family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Direct Memory Access Controller
(DMA)” (DS39742). The information in this
data sheet supersedes the information in
the FRM.
Note:
The Direct Memory Access (DMA) controller is
designed to service high data throughput peripherals
operating on the SFR bus, allowing them to access
data memory directly and alleviating the need for CPU
intensive management. By allowing these data-intensive peripherals to share their own data path, the main
data bus is also deloaded, resulting in additional power
savings.
The DMA controller functions both as a peripheral and
a direct extension of the CPU. It is located on the
microcontroller data bus, between the CPU and DMA
controller-enabled peripherals, with direct access to
SRAM. This partitions the SFR bus into two buses,
allowing the DMA controller access to the DMA
capable peripherals located on the new DMA SFR bus.
The controller serves as a master device on the DMA
SFR bus, controlling data flow from DMA capable
peripherals.
FIGURE 5-1:
The controller also monitors CPU instruction processing directly, allowing it to be aware of when the CPU
requires access to peripherals on the DMA bus, and
automatically relinquishing control to the CPU as
needed. The use of DMA increases the time the
processor can execute code while the DMA is
transferring data.
The DMA controller includes these features:
• Six multiple independent and independently
programmable channels
• Concurrent operation with the CPU (no DMA
caused Wait states)
• DMA bus arbitration
• Five Programmable Address modes
• Four Programmable Transfer modes
• Four Flexible Internal Data Transfer modes
• Byte or word support for data transfer
• 16-Bit Source and Destination Address register
for each channel, dynamically updated and
reloadable
• 16-Bit Transaction Count register, dynamically
updated and reloadable
• Upper and Lower Address Limit registers
• Counter half-full level interrupt
• Software triggered transfer
• Null Write mode for symmetric buffer operations
A simplified block diagram of the DMA controller is
shown if Figure 5-1.

5.1
Summary of DMA Operations
The DMA controller is capable of moving data between
addresses according to a number of different parameters. Each of these parameters can be independently
configured for any transaction. In addition, any or all of
the DMA channels can independently perform a different
transaction at the same time. Transactions are classified
by these parameters:
•
•
•
•
Source and destination (SFRs and data RAM)
Data size (byte or word)
Trigger source
Transfer mode (One-Shot, Repeated or
Continuous)
• Addressing modes (Fixed Address or Address
Blocks, with or without Address Increment/
Decrement)
In addition, the DMA controller provides channel priority
arbitration for all channels.
5.1.1
SOURCE AND DESTINATION
Using the DMA controller, data may be moved between
any two addresses in the Data Space. The SFR space
(0000h to 07FFh), or the data RAM space (0800h to
FFFFh) can serve as either the source or the destination. Data can be moved between these areas in either
direction, or between addresses in either area. The four
different combinations are shown in Figure 5-2.
If it is necessary to protect areas of data RAM, the DMA
controller allows the user to set upper and lower address
boundaries for operations in the Data Space above the
SFR space. The boundaries are set by the DMAH and
DMAL Limit registers. If a DMA channel attempts an
operation outside of the address boundaries, the
transaction is terminated and an interrupt is generated.
5.1.2
DATA SIZE
The DMA controller can handle both 8-bit and 16-bit
transactions. Size is user-selectable using the SIZE bit
(DMACHn<1>). By default, each channel is configured
for word-size transactions. When byte-size transactions are chosen, the LSb of the source and/or
destination address determines if the data represents
the upper or lower byte of the data RAM location.
5.1.3
Since the source and destination addresses for any
transaction can be programmed independently of the
trigger source, the DMA controller can use any trigger
to perform an operation on any peripheral. This also
allows DMA channels to be cascaded to perform more
complex transfer operations.
5.1.4
TRANSFER MODE
The DMA controller supports four types of data
transfers, based on the volume of data to be moved for
each trigger.
• One-Shot: A single transaction occurs for each
trigger.
• Continuous: A series of back-to-back transactions
occur for each trigger. The number of transactions
is determined by the DMACNTn Transaction
Counter register.
• Repeated One-Shot: A single transaction is performed repeatedly, once per trigger, until the DMA
channel is disabled.
• Repeated Continuous: A series of transactions
are performed repeatedly, one cycle per trigger,
until the DMA channel is disabled.
All transfer modes allow the option to have the source
and destination addresses, and counter value automatically reloaded after the completion of a transaction.
Repeated mode transfers do this automatically.
5.1.5
ADDRESSING MODES
The DMA controller also supports transfers between
single addresses or address ranges. The four basic
options are:
• Fixed-to-Fixed: Between two constant addresses
• Fixed-to-Block: From a constant source address
to a range of destination addresses
• Block-to-Fixed: From a range of source
addresses to a single, constant destination
address
• Block-to-Block: From a range to source
addresses to a range of destination addresses
The option to select auto-increment or auto-decrement
of source and/or destination addresses is available for
Block Addressing modes.
TRIGGER SOURCE
The DMA controller can use 63 of the device’s interrupt
sources to initiate a transaction. The DMA trigger
sources occur in reverse order of their natural interrupt
priority and are shown in Table 5-1.
These sources cannot be used as DMA triggers:
• Input Capture 8 and 9
• Output Compare 7, 8 and 9
• USB

5.1.6
CHANNEL PRIORITY
Each DMA channel functions independently of the
others, but also competes with the others for access to
the data and DMA buses. When access collisions
occur, the DMA controller arbitrates between the
channels using a user-selectable priority scheme. Two
schemes are available:
• Round Robin: When two or more channels
collide, the lower numbered channel receives
priority on the first collision. On subsequent collisions, the higher numbered channels each
receive priority based on their channel number.
• Fixed: When two or more channels collide, the
lowest numbered channel always receives
priority, regardless of past history.
5.2
Typical Setup
To set up a DMA channel for a basic data transfer:
1.
Enable the DMA controller (DMAEN = 1) and
select an appropriate channel priority scheme
by setting or clearing PRSSEL.
2. Program DMAH and DMAL with appropriate
upper and lower address boundaries for data
RAM operations.
3. Select the DMA channel to be used and disable
its operation (CHEN = 0).
4. Program the appropriate source and destination
addresses for the transaction into the channel’s
DMASRCn and DMADSTn registers. For PIA
Mode Addressing, use the base address value.
5. Program the DMACNTn register for the number
of triggers per transfer (One-Shot or Continuous
modes) or the number of words (bytes) to be
transferred (Repeated modes).
6. Set or clear the SIZE bit to select the data size.
7. Program the TRMODE<1:0> bits to select the
Data Transfer mode.
8. Program the SAMODE<1:0> and DAMODE<1:0>
bits to select the addressing mode.
9. Enable the DMA channel by setting CHEN.
10. Enable the trigger source interrupt.
DS30009312C-page 86
5.3
Peripheral Module Disable
Unlike other peripheral modules, the channels of the
DMA controller cannot be individually powered down
using the Peripheral Module Disable x (PMDx) registers. Instead, the channels are controlled as two
groups. The DMA0MD bit (PMD7<4>) selectively
controls DMACH0 through DMACH3. The DMA1MD bit
(PMD7<5>) controls DMACH4 and DMACH5. Setting
both bits effectively disables the DMA controller.
5.4
Registers
The DMA controller uses a number of registers to control
its operation. The number of registers depends on the
number of channels implemented for a particular device.
There are always four module-level registers (one
control and three buffer/address registers):
• DMACON: DMA Engine Control Register
(Register 5-1)
• DMAH and DMAL: DMA High and Low Address
Limit Registers
• DMABUF: DMA Data Buffer Register
Each of the DMA channels implements five registers
(two control and three buffer/address registers):
• DMACHn: DMA Channel n Control Register
(Register 5-2)
• DMAINTn: DMA Channel n Interrupt Register
(Register 5-3)
• DMASRCn: DMA Data Source Address Pointer
for Channel n Register
• DMADSTn: DMA Data Destination Source for
Channel n Register
• DMACNTn: DMA Transaction Counter for
Channel n Register
For PIC24FJ128GC010 family devices, there are a
total of 34 DMA registers.

Note:
RTSP is accomplished using TBLRD (Table Read) and
TBLWT (Table Write) instructions. With RTSP, the user
may write program memory data in blocks of 64 instructions (192 bytes) at a time and erase program memory
in blocks of 512 instructions (1536 bytes) at a time.
FLASH PROGRAM MEMORY
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “Program Memory” (DS39715).
The information in this data sheet
supersedes the information in the FRM.
6.1
Regardless of the method used, all programming of
Flash memory is done with the Table Read and Write
instructions. These allow direct read and write access to
the program memory space from the data memory while
the device is in normal operating mode. The 24-bit target
address in the program memory is formed using the
TBLPAG<7:0> bits and the Effective Address (EA) from
a W register, specified in the table instruction, as shown
in Figure 6-1.
The PIC24FJ128GC010 family of devices contains
internal Flash program memory for storing and executing application code. The program memory is readable,
writable and erasable. The Flash can be programmed
in three ways:
• In-Circuit Serial Programming™ (ICSP™)
• Run-Time Self-Programming (RTSP)
• Enhanced In-Circuit Serial Programming
(Enhanced ICSP)
The TBLRDL and the TBLWTL instructions are used to
read or write to bits<15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
ICSP allows a PIC24FJ128GC010 family device to be
serially programmed while in the end application circuit.
This is simply done with two lines for the programming
clock and programming data (named PGECx and
PGEDx, respectively), and three other lines for power
(VDD), ground (VSS) and Master Clear (MCLR). This
allows customers to manufacture boards with
unprogrammed devices and then program the
microcontroller just before shipping the product. This
also allows the most recent firmware or a custom
firmware to be programmed.

The TBLRDH and TBLWTH instructions are used to read

6.2
RTSP Operation
The PIC24F Flash program memory array is organized
into rows of 64 instructions or 192 bytes. RTSP allows
the user to erase blocks of eight rows (512 instructions)
at a time and to program one row at a time. It is also
possible to program single words.
The 8-row erase blocks and single row write blocks are
edge-aligned, from the beginning of program memory, on
boundaries of 1536 bytes and 192 bytes, respectively.
When data is written to program memory using TBLWT
instructions, the data is not written directly to memory.
Instead, data written using Table Writes is stored in
holding latches until the programming sequence is
executed.
Any number of TBLWT instructions can be executed
and a write will be successfully performed. However,
64 TBLWT instructions are required to write the full row
of memory.
To ensure that no data is corrupted during a write,
any unused address should be programmed with
FFFFFFh. This is because the holding latches reset to
an unknown state, so if the addresses are left in the
Reset state, they may overwrite the locations on rows
which were not rewritten.
6.3
Enhanced In-Circuit Serial
Programming
Enhanced In-Circuit Serial Programming uses an
on-board bootloader, known as the Program Executive
(PE), to manage the programming process. Using an
SPI data frame format, the Program Executive can
erase, program and verify program memory. For more
information on Enhanced ICSP, see the device
programming specification.
6.4
Control Registers
There are two SFRs used to read and write the
program Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 6-1) controls which
blocks are to be erased, which memory type is to be
programmed and when the programming cycle starts.
NVMKEY is a write-only register that is used for write
protection. To start a programming or erase sequence,
the user must consecutively write 55h and AAh to the
NVMKEY register. Refer to Section 6.5 “Programming
Operations” for further details.
The basic sequence for RTSP programming is to set up
a Table Pointer, then do a series of TBLWT instructions
to load the buffers. Programming is performed by
setting the control bits in the NVMCON register.
Data can be loaded in any order and the holding registers can be written to multiple times before performing
a write operation. Subsequent writes, however, will
wipe out any previous writes.
Note:
Writing to a location multiple times without
erasing is not recommended.
All of the Table Write operations are single-word writes
(2 instruction cycles), because only the buffers are written. A programming cycle is required for programming
each row.

Programming Operations
4.
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. During a programming or erase operation, the
processor stalls (Waits) until the operation is finished.
Setting the WR bit (NVMCON<15>) starts the operation and the WR bit is automatically cleared when the
operation is finished.
6.5.1
5.
PROGRAMMING ALGORITHM FOR
FLASH PROGRAM MEMORY
The user can program one row of Flash program memory
at a time. To do this, it is necessary to erase the 8-row
erase block containing the desired row. The general
process is:
1.
2.
3.
6.
Read eight rows of program memory
(512 instructions) and store in data RAM.
Update the program data in RAM with the
desired new data.
Erase the block (see Example 6-1):
a) Set the NVMOPx bits (NVMCON<3:0>) to
�0010’ to configure for the block erase. Set
the ERASE (NVMCON<6>) and WREN
(NVMCON<14>) bits.
b) Write the starting address of the block to be
erased into the TBLPAG and W registers.
c) Write 55h to NVMKEY.
d) Write AAh to NVMKEY.
e) Set the WR bit (NVMCON<15>). The erase
cycle begins and the CPU stalls for the duration of the erase cycle. When the erase is
EXAMPLE 6-1:
#0x55, W0
W0, NVMKEY
#0xAA, W1
W1, NVMKEY
NVMCON, #WR
DS30009312C-page 94
For protection against accidental operations, the write
initiate sequence for NVMKEY must be used to allow
any erase or program operation to proceed. After the
programming command has been executed, the user
must wait for the programming time until programming
is complete. The two instructions following the start of
the programming sequence should be NOPs, as shown
in Example 6-4.

done, the WR bit is cleared automatically.
Write the first 64 instructions from data RAM into
the program memory buffers (see Example 6-3).
Write the program block to Flash memory:
a) Set the NVMOPx bits to �0001’ to configure
for row programming. Clear the ERASE bit
and set the WREN bit.
b) Write 55h to NVMKEY.
c) Write AAh to NVMKEY.
d) Set the WR bit. The programming cycle
begins and the CPU stalls for the duration
of the write cycle. When the write to Flash
memory is done, the WR bit is cleared
automatically.
Repeat Steps 4 and 5, using the next available
64 instructions from the block in data RAM by
incrementing the value in TBLPAG, until all
512 instructions are written back to Flash
memory.

PROGRAMMING A SINGLE WORD
OF FLASH PROGRAM MEMORY
If a Flash location has been erased, it can be programmed using Table Write instructions to write an
instruction word (24-bit) into the write latch. The
TBLPAG register is loaded with the 8 Most Significant
Bytes (MSBs) of the Flash address. The TBLWTL and
TBLWTH instructions write the desired data into the
EXAMPLE 6-5:
write latches and specify the lower 16 bits of the
program memory address to write to. To configure the
NVMCON register for a word write, set the NVMOPx
bits (NVMCON<3:0>) to �0011’. The write is performed
by executing the unlock sequence and setting the WR
bit (see Example 6-5). An equivalent procedure in �C’
compiler, using the MPLABВ® XC compiler and built-in
hardware functions, is shown in Example 6-6.

RESETS
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “Reset” (DS39712). The information in this data sheet supersedes the
information in the FRM.
The Reset module combines all Reset sources and
controls the device Master Reset Signal, SYSRST. The
following is a list of device Reset sources:
•
•
•
•
•
•
•
•
•
POR: Power-on Reset
MCLR: Pin Reset
SWR: RESET Instruction
WDT: Watchdog Timer Reset
BOR: Brown-out Reset
CM: Configuration Mismatch Reset
TRAPR: Trap Conflict Reset
IOPUWR: Illegal Opcode Reset
UWR: Uninitialized W Register Reset
Any active source of Reset will make the SYSRST
signal active. Many registers associated with the CPU
and peripherals are forced to a known Reset state.
Most registers are unaffected by a Reset; their status is
unknown on POR and unchanged by all other Resets.
Note:
A device Reset will set a corresponding status bit in the
RCON register to indicate the type of Reset (see
Register 7-1). In addition, Reset events occurring while
an extreme power-saving feature is in use (such as
VBAT) will set one or more status bits in the RCON2
register (Register 7-2). A POR will clear all bits, except
for the BOR and POR (RCON<1:0>) bits, which are
set. The user may set or clear any bit at any time during
code execution. The RCON bits only serve as status
bits. Setting a particular Reset status bit in software will
not cause a device Reset to occur.
The RCON register also has other bits associated with
the Watchdog Timer and device power-saving states.
The function of these bits is discussed in other sections
of this data sheet.
A simplified block diagram of the Reset module is
shown in Figure 7-1.
FIGURE 7-1:
Refer to the specific peripheral or CPU
section of this manual for register Reset
states.
Note:
The status bits in the RCON registers
should be cleared after they are read so
that the next RCON register values after a
device Reset will be meaningful.

7.1
Special Function Register Reset
States
Most of the Special Function Registers (SFRs) associated with the PIC24F CPU and peripherals are reset to a
particular value at a device Reset. The SFRs are
grouped by their peripheral or CPU function and their
Reset values are specified in each section of this manual.
The Reset value for each SFR does not depend on the
type of Reset, with the exception of four registers. The
Reset value for the Reset Control register, RCON, will
depend on the type of device Reset. The Reset value
for the Oscillator Control register, OSCCON, will
depend on the type of Reset and the programmed
values of the FNOSCx bits in Flash Configuration
Word 2 (CW2) (see Table 7-2). The RCFGCAL and
NVMCON registers are only affected by a POR.
7.2
Device Reset Times
The Reset times for various types of device Reset are
summarized in Table 7-3. Note that the Master Reset
Signal, SYSRST, is released after the POR delay time
expires.
The time at which the device actually begins to execute
code will also depend on the system oscillator delays,
which include the Oscillator Start-up Timer (OST) and
the PLL lock time. The OST and PLL lock times occur
in parallel with the applicable SYSRST delay times.
The Fail-Safe Clock Monitor (FSCM) delay determines
the time at which the FSCM begins to monitor the
system clock source after the SYSRST signal is
released.
пѓЈ 2012-2014 Microchip Technology Inc.
7.3
Brown-out Reset (BOR)
PIC24FJ128GC010 family devices implement a BOR
circuit that provides the user with several configuration
and power-saving options. The BOR is controlled by
the BOREN (CW3<12>) Configuration bit.
When BOR is enabled, any drop of VDD below the BOR
threshold results in a device BOR. Threshold levels are
described in Section 37.1 “DC Characteristics”
(Parameter DC17b).
7.4
Clock Source Selection at Reset
If clock switching is enabled, the system clock source at
device Reset is chosen, as shown in Table 7-2. If clock
switching is disabled, the system clock source is always
selected according to the Oscillator Configuration bits.
Refer to the “dsPIC33/PIC24 Family Reference Manual”,
“Oscillator” (DS39700) for further details.

7.4.1
TPOR = Power-on Reset delay (10 пЃ­s nominal).
TSTARTUP = TVREG.
TRST = Internal State Reset time (2 пЃ­s nominal).
TOST = Oscillator Start-up Timer (OST). A 10-bit counter counts 1024 oscillator periods before releasing
the oscillator clock to the system.
TLOCK = PLL lock time.
TFRC and TLPRC = RC Oscillator start-up times.
If Two-Speed Start-up is enabled, regardless of the primary oscillator selected, the device starts with FRC,
so the system clock delay is just TFRC, and in such cases, FRC start-up time is valid. It switches to the
primary oscillator after its respective clock delay.
POR AND LONG OSCILLATOR
START-UP TIMES
The oscillator start-up circuitry and its associated delay
timers are not linked to the device Reset delays that
occur at power-up. Some crystal circuits (especially
low-frequency crystals) will have a relatively long
start-up time. Therefore, one or more of the following
conditions is possible after SYSRST is released:
• The oscillator circuit has not begun to oscillate.
• The Oscillator Start-up Timer has not expired (if a
crystal oscillator is used).
• The PLL has not achieved a lock (if PLL is used).
DS30009312C-page 102
The device will not begin to execute code until a valid
clock source has been released to the system. Therefore, the oscillator and PLL start-up delays must be
considered when the Reset delay time must be known.
7.4.2
FAIL-SAFE CLOCK MONITOR
(FSCM) AND DEVICE RESETS
If the FSCM is enabled, it will begin to monitor the
system clock source when SYSRST is released. If a
valid clock source is not available at this time, the
device will automatically switch to the FRC Oscillator
and the user can switch to the desired crystal oscillator
in the Trap Service Routine (TSR).

Note:
INTERRUPT CONTROLLER
This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “Interrupts” (DS70000600). The
information in this data sheet supersedes
the information in the FRM.
The PIC24F interrupt controller reduces the numerous
peripheral interrupt request signals to a single interrupt
request signal to the PIC24F CPU. It has the following
features:
•
•
•
•
Up to 8 processor exceptions and software traps
Seven user-selectable priority levels
Interrupt Vector Table (IVT) with up to 118 vectors
Unique vector for each interrupt or exception
source
• Fixed priority within a specified user priority level
• Alternate Interrupt Vector Table (AIVT) for debug
support
• Fixed interrupt entry and return latencies
8.1
Interrupt Vector Table
The Interrupt Vector Table (IVT) is shown in Figure 8-1.
The IVT resides in program memory, starting at location,
000004h. The IVT contains 126 vectors, consisting of
8 non-maskable trap vectors, plus up to 118 source
interrupts. In general, each interrupt source has its own
vector. Each interrupt vector contains a 24-bit wide
address. The value programmed into each interrupt vector location is the starting address of the associated
Interrupt Service Routine (ISR).
8.1.1
ALTERNATE INTERRUPT VECTOR
TABLE
The Alternate Interrupt Vector Table (AIVT) is located
after the IVT, as shown in Figure 8-1. The ALTIVT
(INTCON2<15>) control bit provides access to the
AIVT. If the ALTIVT bit is set, all interrupt and exception
processes will use the alternate vectors instead of the
default vectors. The alternate vectors are organized in
the same manner as the default vectors.
The AIVT supports emulation and debugging efforts by
providing a means to switch between an application,
and a support environment, without requiring the interrupt vectors to be reprogrammed. This feature also
enables switching between applications for evaluation
of different software algorithms at run time. If the AIVT
is not needed, the AIVT should be programmed with
the same addresses used in the IVT.
8.2
Reset Sequence
A device Reset is not a true exception because the
interrupt controller is not involved in the Reset process.
The PIC24F devices clear their registers in response to
a Reset, which forces the PC to zero. The microcontroller then begins program execution at location,
000000h. The user programs a GOTO instruction at the
Reset address, which redirects program execution to
the appropriate start-up routine.
Note:
Any unimplemented or unused vector
locations in the IVT and AIVT should be
programmed with the address of a default
interrupt handler routine that contains a
RESET instruction.
Interrupt vectors are prioritized in terms of their natural
priority; this is linked to their position in the vector table.
All other things being equal, lower addresses have a
higher natural priority. For example, the interrupt associated with Vector 0 will take priority over interrupts at
any other vector address.

Interrupt Control and Status
Registers
The PIC24FJ128GC010 family of devices implements
a total of 44 registers for the interrupt controller:
•
•
•
•
•
INTCON1
INTCON2
IFS0 through IFS7
IEC0 through IEC7
IPC0 through IPC13, ICP15, ICP16, ICP18
through ICP23, ICP25, ICP26 and ICP29
• INTTREG
Global interrupt control functions are controlled from
INTCON1 and INTCON2. INTCON1 contains the Interrupt Nesting Disable (NSTDIS) bit, as well as the
control and status flags for the processor trap sources.
The INTCON2 register controls the external interrupt
request signal behavior and the use of the Alternate
Interrupt Vector Table (AIVT).
The IFSx registers maintain all of the interrupt request
flags. Each source of interrupt has a status bit, which is
set by the respective peripherals or an external signal
and is cleared via software.
The IECx registers maintain all of the interrupt enable
bits. These control bits are used to individually enable
interrupts from the peripherals or external signals.
The IPCx registers are used to set the Interrupt Priority
Level (IPL) for each source of interrupt. Each user
interrupt source can be assigned to one of eight priority
levels.
The interrupt sources are assigned to the IFSx, IECx
and IPCx registers in the order of their vector numbers,
as shown in Table 8-2. For example, the INT0 (External
Interrupt 0) is shown as having a vector number and a
natural order priority of 0. Thus, the INT0IF status bit is
found in IFS0<0>, the INT0IE enable bit in IEC0<0>
and the INT0IP<2:0> priority bits in the first position of
IPC0 (IPC0<2:0>).
Although they are not specifically part of the interrupt
control hardware, two of the CPU Control registers contain bits that control interrupt functionality. The ALU
STATUS Register (SR) contains the IPL<2:0> bits
(SR<7:5>). These indicate the current CPU Interrupt
Priority Level. The user can change the current CPU
priority level by writing to the IPLx bits.
The CORCON register contains the IPL3 bit, which
together with the IPL<2:0> bits, indicates the current
CPU priority level. IPL3 is a read-only bit so that trap
events cannot be masked by the user software.
The interrupt controller has the Interrupt Controller Test
register, INTTREG, which displays the status of the
interrupt controller. When an interrupt request occurs,
its associated vector number and the new Interrupt Priority Level are latched into INTTREG. This information
can be used to determine a specific interrupt source if
a generic ISR is used for multiple vectors (such as
when ISR remapping is used in bootloader applications) or to check if another interrupt is pending while in
an ISR.
All Interrupt registers are described in Register 8-1
through Register 8-46 in the succeeding pages.
The INTTREG register contains the associated
interrupt vector number and the new CPU Interrupt
Priority Level, which are latched into the Vector
Number (VECNUM<6:0>) and the Interrupt Level
(ILR<3:0>) bit fields in the INTTREG register. The new
Interrupt Priority Level is the priority of the pending
interrupt.

See Register 3-1 for the description of the remaining bits (bits 8, 4, 3, 2, 1 and 0) that are not dedicated to
interrupt control functions.
The IPLx bits are concatenated with the IPL3 (CORCON<3>) bit to form the CPU Interrupt Priority Level.
The value in parentheses indicates the Interrupt Priority Level if IPL3 = 1.
The IPLx Status bits are read-only when NSTDIS (INTCON1<15>) = 1.

Interrupt Setup Procedures
8.4.1
INITIALIZATION
To configure an interrupt source:
1.
2.
Set the NSTDIS (INTCON1<15>) control bit if
nested interrupts are not desired.
Select the user-assigned priority level for the
interrupt source by writing the control bits in the
appropriate IPCx register. The priority level will
depend on the specific application and type of
interrupt source. If multiple priority levels are not
desired, the IPCx register control bits for all
enabled interrupt sources may be programmed
to the same non-zero value.
Note:
3.
4.
At a device Reset, the IPCx registers are
initialized such that all user interrupt
sources are Priority Level 4.
Clear the interrupt flag status bit associated with
the peripheral in the associated IFSx register.
Enable the interrupt source by setting the
interrupt enable control bit associated with the
source in the appropriate IECx register.
8.4.2
8.4.3
TRAP SERVICE ROUTINE (TSR)
A Trap Service Routine (TSR) is coded like an ISR,
except that the appropriate trap status flag in the
INTCON1 register must be cleared to avoid re-entry
into the TSR.
8.4.4
INTERRUPT DISABLE
All user interrupts can be disabled using the following
procedure:
1.
2.
Push the current SR value onto the software
stack using the PUSH instruction.
Force the CPU to Priority Level 7 by inclusive
ORing the value, 0Eh, with SR.
To enable user interrupts, the POP instruction may be
used to restore the previous SR value.
Note that only user interrupts with a priority level of 7 or
less can be disabled. Trap sources (Levels 8-15) cannot
be disabled.
The DISI instruction provides a convenient way to
disable interrupts of Priority Levels 1-6 for a fixed
period of time. Level 7 interrupt sources are not
disabled by the DISI instruction.
INTERRUPT SERVICE ROUTINE
(ISR)
The method that is used to declare an Interrupt Service
Routine (ISR) and initialize the IVT with the correct vector address will depend on the programming language
(i.e., �C’ or assembler), and the language development
toolsuite that is used to develop the application. In
general, the user must clear the interrupt flag in the
appropriate IFSx register for the source of the interrupt
that the ISR handles; otherwise, the ISR will be
re-entered immediately after exiting the routine. If the
ISR is coded in assembly language, it must be terminated using a RETFIE instruction to unstack the saved
PC value, SR value and old CPU priority level.

Note:
This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive reference source. For more information, refer
to the “dsPIC33/PIC24 Family Reference
Manual”, “Oscillator” (DS39700).
The oscillator system for the PIC24FJ128GC010 family
devices has the following features:
• A total of four external and internal oscillator options
as clock sources, providing 11 different Clock modes

CPU Clocking Scheme
9.2
The system clock source can be provided by one of
four sources:
• Primary Oscillator (POSC) on the OSCI and
OSCO pins
• Secondary Oscillator (SOSC) on the SOSCI and
SOSCO pins
• Fast Internal RC (FRC) Oscillator
• Low-Power Internal RC (LPRC) Oscillator
The Primary Oscillator and FRC sources have the
option of using the internal USB PLL block, which
generates both the USB module clock and a separate
system clock from the 96 MHZ PLL. Refer to
Section 9.6 “Oscillator Modes and USB Operation”
for additional information.
The internal FRC provides an 8 MHz clock source. It
can optionally be reduced by the programmable clock
divider to provide a range of system clock frequencies.
The selected clock source generates the processor
and peripheral clock sources. The processor clock
source is divided by two to produce the internal instruction cycle clock, FCY. In this document, the instruction
cycle clock is also denoted by FOSC/2. The internal
instruction cycle clock, FOSC/2, can be provided on the
OSCO I/O pin for some operating modes of the Primary
Oscillator.
TABLE 9-1:
Initial Configuration on POR
The oscillator source (and operating mode) that is used
at a device Power-on Reset event is selected using
Configuration bit settings. The Oscillator Configuration
bit settings are located in the Configuration registers in
the program memory (refer to Section 34.1 “Configuration Bits” for further details). The Primary Oscillator

Word 2<1:0>), and the Initial Oscillator Select Configuration bits, FNOSC<2:0> (Configuration Word 2<10:8>),
select the oscillator source that is used at a Power-on
Reset. The FRC Primary Oscillator with Postscaler
(FRCDIV) is the default (unprogrammed) selection.
The Secondary Oscillator (SOSC), or one of the internal oscillators, may be chosen by programming these
bit locations.
The Configuration bits allow users to choose between
the various clock modes, shown in Table 9-1.

CLOCK SWITCHING MODE
CONFIGURATION BITS
The FCKSM<1:0> Configuration bits (Configuration
Word 2<7:6>) are used to jointly configure device clock
switching and the Fail-Safe Clock Monitor (FSCM).
Clock switching is enabled only when FCKSM1 is
programmed (�0’). The FSCM is enabled only when
FCKSM<1:0> are both programmed (�00’).

Control Registers
The operation of the oscillator is controlled by three
Special Function Registers:
• OSCCON
• CLKDIV
• OSCTUN
The OSCCON register (Register 9-1) is the main control register for the oscillator. It controls clock source
switching and allows the monitoring of clock sources.
REGISTER 9-1:
OSCCON is protected by a write lock to prevent
inadvertent clock switches. See Section 9.4 “Clock
Switching Operation” for more information.
The CLKDIV register (Register 9-2) controls the
features associated with Doze mode, as well as the
postscaler for the FRC Oscillator.
The OSCTUN register (Register 9-3) allows the user to
fine-tune the FRC Oscillator over a range of approximately В±1.5%. It also controls the FRC self-tuning
features, described in Section 9.5 “FRC Active Clock
Tuning”.

9.4
Clock Switching Operation
With few limitations, applications are free to switch
between any of the four clock sources (POSC, SOSC,
FRC and LPRC) under software control and at any
time. To limit the possible side effects that could result
from this flexibility, PIC24F devices have a safeguard
lock built into the switching process.
Note:
9.4.1
The Primary Oscillator mode has three
different submodes (XT, HS and EC)
which are determined by the POSCMDx
Configuration bits. While an application
can switch to and from Primary Oscillator
mode in software, it cannot switch
between the different primary submodes
without reprogramming the device.
ENABLING CLOCK SWITCHING
To enable clock switching, the FCKSM1 Configuration
bit in CW2 must be programmed to �0’. (Refer to
Section 34.1 “Configuration Bits” for further details.)
If the FCKSM1 Configuration bit is unprogrammed (�1’),
the clock switching function and Fail-Safe Clock
Monitor function are disabled; this is the default setting.
The NOSCx control bits (OSCCON<10:8>) do not control
the clock selection when clock switching is disabled.
However, the COSC<2:0> bits (OSCCON<14:12>) will
reflect the clock source selected by the FNOSCx
Configuration bits.
The OSWEN control bit (OSCCON<0>) has no effect
when clock switching is disabled; it is held at �0’ at all
times.
9.4.2
OSCILLATOR SWITCHING
SEQUENCE
At a minimum, performing a clock switch requires this
basic sequence:
1.
2.
3.
4.
5.
If
desired,
read
the
COSCx
bits
(OSCCON<14:12>) to determine the current
oscillator source.
Perform the unlock sequence to allow a write to
the OSCCON register high byte.
Write the appropriate value to the NOSCx bits
(OSCCON<10:8>) for the new oscillator source.
Perform the unlock sequence to allow a write to
the OSCCON register low byte.
Set the OSWEN bit to initiate the oscillator
switch.
пѓЈ 2012-2014 Microchip Technology Inc.
Once the basic sequence is completed, the system
clock hardware responds automatically as follows:
1.
2.
3.
4.
5.
6.
The clock switching hardware compares the
COSCx bits with the new value of the NOSCx
bits. If they are the same, then the clock switch
is a redundant operation. In this case, the
OSWEN bit is cleared automatically and the
clock switch is aborted.
If a valid clock switch has been initiated, the
LOCK (OSCCON<5>) and CF (OSCCON<3>)
bits are cleared.
The new oscillator is turned on by the hardware
if it is not currently running. If a crystal oscillator
must be turned on, the hardware will wait until
the OST expires. If the new source is using the
PLL, then the hardware waits until a PLL lock is
detected (LOCK = 1).
The hardware waits for 10 clock cycles from the
new clock source and then performs the clock
switch.
The hardware clears the OSWEN bit to indicate a
successful clock transition. In addition, the
NOSCx bit values are transferred to the COSCx
bits.
The old clock source is turned off at this time,
with the exception of LPRC (if WDT or FSCM is
enabled) or SOSC (if SOSCEN remains set).
Note 1: The processor will continue to execute
code throughout the clock switching
sequence. Timing-sensitive code should
not be executed during this time.
2: Direct clock switches between any
Primary Oscillator mode with PLL and
FRCPLL mode are not permitted. This
applies to clock switches in either direction. In these instances, the application
must switch to FRC mode as a transitional clock source between the two PLL
modes.
DS30009312C-page 165
PIC24FJ128GC010 FAMILY
A recommended code sequence for a clock switch
includes the following:
1.
2.
3.
4.
5.
6.
7.
8.
Disable interrupts during the OSCCON register
unlock and write sequence.
Execute the unlock sequence for the OSCCON
high byte by writing 78h and 9Ah to
OSCCON<15:8> in two back-to-back instructions.
Write the new oscillator source to the NOSCx
bits in the instruction immediately following the
unlock sequence.
Execute the unlock sequence for the OSCCON
low byte by writing 46h and 57h to
OSCCON<7:0> in two back-to-back instructions.
Set the OSWEN bit in the instruction immediately
following the unlock sequence.
Continue to execute code that is not clock-sensitive
(optional).
Invoke an appropriate amount of software delay
(cycle counting) to allow the selected oscillator
and/or PLL to start and stabilize.
Check to see if OSWEN is �0’. If it is, the switch
was successful. If OSWEN is still set, then
check the LOCK bit to determine the cause of
the failure.
The core sequence for unlocking the OSCCON register
and initiating a clock switch is shown in Example 9-1.

FRC Active Clock Tuning
PIC24FJ128GC010 family devices include an automatic
mechanism to calibrate the FRC during run time. This
system uses active clock tuning from a source of known
accuracy to maintain the FRC within a very narrow
margin of its nominal 8 MHz frequency. This allows for a
frequency accuracy that is well within the requirements
of the “USB 2.0 Specification”, regarding full-speed USB
devices.
Note:
The self-tune feature maintains sufficient
accuracy for operation in USB Device
mode. For applications that function as a
USB host, a high-accuracy clock source
(В±0.05%) is still required.
The self-tune system is controlled by the bits in the
upper half of the OSCTUN register. Setting the STEN
bit (OSCTUN<15>) enables the self-tuning feature,
allowing the hardware to calibrate to a source selected
by the STSRC bit (OSCTUN<12>). When STSRC = 1,
the system uses the Start-of-Frame (SOF) packets
from an external USB host for its source. When
STSRC = 0, the system uses the crystal controlled
SOSC for its calibration source. Regardless of the
source, the system uses the TUN<5:0> bits
(OSCTUN<5:0>) to change the FRC Oscillator’s frequency. Frequency monitoring and adjustment is
dynamic, occurring continuously during run time. While
the system is active, the TUNx bits cannot be written to
by software.
Note:
To use the USB as a reference clock
tuning source (STSRC = 1), the microcontroller must be configured for USB
device operation and connected to a
non-suspended USB host or hub port.
If the SOSC is to be used as the reference
clock tuning source (STSRC = 0), the
SOSC must also be enabled for clock
tuning to occur.
The self-tune system can generate a hardware
interrupt, FSTIF. This interrupt can result from a drift
of the FRC from the reference by greater than 0.2% in
either direction, or whenever the frequency deviation
is beyond the ability of the TUNx bits to correct (i.e.,
greater than 1.5%). The STLOCK and STOR status
bits (OSCTUN<11,9>) are used to indicate these
conditions.
The STLPOL and STORPOL bits (OSCTUN<10,8>)
configure the FSTIF interrupt to occur in the presence
or the absence of these conditions. It is the user’s
responsibility to monitor both the STLOCK and STOR
bits to determine the exact cause of the interrupt.
Note:
DS30009312C-page 166
The STLPOL and STORPOL bits should
be ignored when the self-tune system is
disabled (STEN = 0).

TABLE 9-2:
Oscillator Modes and USB
Operation
Because of the timing requirements imposed by USB,
an internal clock of 48 MHz is required at all times while
the USB module is enabled and not in a suspended
operating state. Since this is well beyond the maximum
CPU clock speed, a method is provided to internally
generate both the USB and system clocks from a single
oscillator source. PIC24FJ128GC010 family devices
use the same clock structure as most other PIC24FJ
devices, but include a two-branch PLL system to
generate the two clock signals.
The USB PLL block is shown in Figure 9-2. In this
system, the input from the Primary Oscillator is divided
down by a PLL prescaler to generate a 4 MHz output.
This is used to drive an on-chip, 96 MHz PLL frequency
multiplier to drive the two clock branches. One branch
uses a fixed, divide-by-2 frequency divider to generate
the 48 MHz USB clock. The other branch uses a fixed,
divide-by-3 frequency divider and configurable PLL
prescaler/divider to generate a range of system clock
frequencies. The CPDIV<1:0> bits select the system
clock speed; available clock options are listed in
Table 9-2.
The USB PLL prescaler does not automatically sense
the incoming oscillator frequency. The user must manually configure the PLL divider to generate the required
4 MHz output, using the PLLDIV<3:0> Configuration
bits. This limits the choices for Primary Oscillator
frequency to a total of 8 possibilities, shown in
Table 9-3.

CONSIDERATIONS FOR USB
OPERATION
When using the USB On-The-Go module in
PIC24FJ128GC010 family devices, users must always
observe these rules in configuring the system clock:
• The oscillator modes listed in Table 9-3 are the
only oscillator configurations that permit USB operation. There is no provision to provide a separate
external clock source to the USB module.
• For USB operation, the selected clock source
(EC, HS or XT) must meet the USB clock
tolerance requirements.
• When the FRCPLL Oscillator mode is used for
USB applications, the FRC self-tune system
should be used as well. While the FRC is accurate, the only two ways to ensure the level of
accuracy required by the “USB 2.0 Specification”,
throughout the application’s operating range, are
either the self-tune system or manually changing
the TUN<5:0> bits.
• The user must always ensure that the FRC
source is configured to provide a frequency of
4 MHz or 8 MHz (RCDIV<2:0> = 001 or 000) and
that the USB PLL prescaler is configured
appropriately.
• All other oscillator modes are available; however,
USB operation is not possible when these modes
are selected. They may still be useful in cases
where other power levels of operation are
desirable and the USB module is not needed
(e.g., the application is Sleeping and waiting for
a bus attachment).
9.7
Reference Clock Output
In addition to the CLKO output (FOSC/2) available in
certain oscillator modes, the device clock in the
PIC24FJ128GC010 family devices can also be configured to provide a reference clock output signal to a port
pin. This feature is available in all oscillator configurations and allows the user to select a greater range of
clock submultiples to drive external devices in the
application.
This reference clock output is controlled by the
REFOCON register (Register 9-4). Setting the ROEN bit
(REFOCON<15>) makes the clock signal available on
the REFO pin. The RODIV<3:0> bits (REFOCON<11:8>)
enable the selection of 16 different clock divider options.
The ROSSLP and ROSEL bits (REFOCON<13:12>)
control the availability of the reference output during
Sleep mode. The ROSEL bit determines if the oscillator
on OSC1 and OSC2, or the current system clock
source, is used for the reference clock output. The
ROSSLP bit determines if the reference source is
available on REFO when the device is in Sleep mode.
DS30009312C-page 168
To use the reference clock output in Sleep mode, both
the ROSSLP and ROSEL bits must be set. The device
clock must also be configured for one of the Primary
modes (EC, HS or XT); otherwise, if the POSCEN bit is
not also set, the oscillator on OSC1 and OSC2 will be
powered down when the device enters Sleep mode.
Clearing the ROSEL bit allows the reference output
frequency to change as the system clock changes
during any clock switches.
9.8
9.8.1
Secondary Oscillator
BASIC SOSC OPERATION
PIC24FJ128GC010 family devices do not have to set
the SOSCEN bit to use the Secondary Oscillator. Any
module requiring the SOSC (such as RTCC, Timer1 or
DSWDT) will automatically turn on the SOSC when the
clock signal is needed. The SOSC, however, has a long
start-up time (as long as 1 second).To avoid delays for
peripheral start-up, the SOSC can be manually started
using the SOSCEN bit.
To use the Secondary Oscillator, the SOSCSEL bit
(CW3<8>) must be set to �1’. Programming the
SOSCSEL bit to �0’ configures the SOSC pins for Digital
mode, enabling digital I/O functionality on the pins.
9.8.2
CRYSTAL SELECTION
The 32.768 kHz crystal used for the SOSC must have
the following specifications in order to properly start up
and run at the correct frequency:
• 12.5 pF loading capacitance
• 1.0 pF shunt capacitance
• A typical ESR of 50K; 70K maximum
In addition, the two external crystal loading capacitors
should be in the range of 22-27 pF, which will be based
on the PC board layout. The capacitors should be C0G,
5% tolerance and rated 25V or greater.
The accuracy and duty cycle of the SOSC can be
measured on the REFO pin and is recommended to be
in the range of 40-60% and accurate to В±0.65Hz.
Note:
Do not enable the LCD Segment pin,
SEG17, on RD0 when using the 64-pin
package if the SOSC is used for timesensitive applications. Avoid high-frequency
traces adjacent to the SOSCO and SOSCI
pins as this can cause errors in the SOSC
frequency and/or duty cycle.

POWER-SAVING FEATURES
This data sheet summarizes the features
of this group of PIC24 devices. It is not
intended to be a comprehensive
reference source. For more information,
refer to the “dsPIC33/PIC24 Family
Reference Manual”, “Power-Saving
Features with Deep Sleep” (DS39727).
Note:
The PIC24FJ128GC010 family of devices provides the
ability to manage power consumption by selectively managing clocking to the CPU and the peripherals. In general,
a lower clock frequency and a reduction in the number of
circuits being clocked reduces consumed power.
PIC24FJ128GC010 family devices manage power
consumption with five strategies:
•
•
•
•
•
Instruction-Based Power Reduction Modes
Hardware-Based Power Reduction Features
Clock Frequency Control
Software Controlled Doze Mode
Selective Peripheral Control in Software
10.1
Overview of Power-Saving Modes
In addition to full-power operation, otherwise known as
Run mode, the PIC24FJ128GC010 family of devices
offers three instruction-based power-saving modes and
one hardware-based mode:
•
•
•
•
Idle/Doze
Sleep (Sleep and Low-Voltage Sleep)
Deep Sleep (with and without retention)
VBAT (with and without RTCC)
These four power modes offer different current consumption levels and have different degrees of
functionality. Table 10-1 lists all of the operating modes
in order of increasing power savings. Table 10-2 summarizes how the microcontroller exits the different
modes. Specific information is provided in the following
sections.
Combinations of these methods can be used to
selectively tailor an application’s power consumption,
while still maintaining critical application features, such
as timing-sensitive communications.

10.1.1
INSTRUCTION-BASED
POWER-SAVING MODES
These built-in functions are equivalent to the PWRSAV
assembly instructions.
Three of the power-saving modes are entered through
the execution of the PWRSAV instruction. Sleep mode
stops clock operation and halts all code execution. Idle
mode halts the CPU and code execution, but allows
peripheral modules to continue operation. Deep Sleep
mode stops clock operation, code execution and all
peripherals, except RTCC and DSWDT. It also freezes
I/O states and removes power to Flash memory, and
may remove power to SRAM.
The features enabled with the low-voltage/retention
regulator result in some changes to the way that Sleep
and Deep Sleep modes behave. See Section 10.3
“Sleep Mode” and Section 10.4 “Deep Sleep Mode”
for additional information.
The assembly syntax of the PWRSAV instruction is shown
in Example 10-1. Sleep and Idle modes are entered
directly with a single assembler command. Deep Sleep
requires an additional sequence to unlock and enable
the entry into Deep Sleep, which is described in
Section 10.4.2 “Entering Deep Sleep Mode”.
Note:
SLEEP_MODE and IDLE_MODE are
constants defined in the assembler
include file for the selected device.
Sleep and Idle modes can be exited as a result of an
enabled interrupt, WDT time-out or a device Reset. When
the device exits these modes, it is said to “wake-up”.
When using the MPLABВ® C compilers, there are two
special power-saving instructions:
10.1.1.1
Interrupts Coincident with
Power Save Instructions
Any interrupt that coincides with the execution of a
PWRSAV instruction will be held off until entry into Sleep
or Idle mode has completed. The device will then
wake-up from Sleep or Idle mode.
For Deep Sleep mode, interrupts that coincide with the
execution of the PWRSAV instruction may be lost. If the
low-voltage/retention regulator is not enabled, the
microcontroller resets on leaving Deep Sleep and the
interrupt will be lost. If the low-voltage/retention regulator is enabled, the microcontroller will exit Deep Sleep
and the interrupt will then be handled.
Interrupts that occur during the Deep Sleep unlock
sequence will interrupt the mandatory five-instruction
cycle sequence timing and cause a failure to enter Deep
Sleep. For this reason, it is recommended to disable all
interrupts during the Deep Sleep unlock sequence.
• Sleep();
• Idle();

PIC24FJ128GC010 FAMILY
10.1.2
HARDWARE-BASED
POWER-SAVING MODE
The hardware-based VBAT mode does not require any
action by the user during code development. Instead, it
is a hardware design feature that allows the microcontroller to retain critical data (using the DSGPRx
registers) and maintain the RTCC when VDD is removed
from the application. This is accomplished by supplying
a backup power source to a specific power pin. VBAT
mode is described in more detail in Section 10.5 “VBAT
Mode”.
10.1.3
LOW-VOLTAGE/RETENTION
REGULATOR
PIC24FJ128GC010 family devices incorporate a
second on-chip voltage regulator, designed to provide
power to select microcontroller features at 1.2V nominal. This regulator allows features, such as data RAM
and the WDT, to be maintained in power-saving modes
where they would otherwise be inactive, or maintain
them at a lower power than would otherwise be the
case.
The low-voltage/retention regulator is only available
when Sleep or Deep Sleep modes are invoked. It is
controlled by the LPCFG Configuration bit (CW1<10>)
and in firmware by the RETEN bit (RCON<12>).
LPCFG must be programmed (= 0) and the RETEN bit
must be set (= 1) for the regulator to be enabled.
10.2
Idle Mode
Idle mode provides these features:
• The CPU will stop executing instructions.
• The WDT is automatically cleared.
• The system clock source remains active. By
default, all peripheral modules continue to operate
normally from the system clock source, but can
also be selectively disabled (see Section 10.8
“Selective Peripheral Module Control”).
• If the WDT or FSCM is enabled, the LPRC will
also remain active.
The device will wake from Idle mode on any of these
events:
• Any interrupt that is individually enabled
• Any device Reset
• A WDT time-out
On wake-up from Idle, the clock is reapplied to the CPU
and instruction execution begins immediately, starting
with the instruction following the PWRSAV instruction or
the first instruction in the Interrupt Service Routine
(ISR).
DS30009312C-page 174
10.3
Sleep Mode
Sleep mode includes these features:
• The system clock source is shut down. If an
on-chip oscillator is used, it is turned off.
• The device current consumption will be reduced
to a minimum provided that no I/O pin is sourcing
current.
• The I/O pin directions and states are frozen.
• The Fail-Safe Clock Monitor does not operate
during Sleep mode since the system clock source
is disabled.
• The LPRC clock will continue to run in Sleep
mode if the WDT or RTCC, with LPRC as the
clock source, is enabled.
• The WDT, if enabled, is automatically cleared
prior to entering Sleep mode.
• Some device features or peripherals may
continue to operate in Sleep mode. This includes
items, such as the Input Change Notification
(ICN) on the I/O ports or peripherals that use an
external clock input. Any peripheral that requires
the system clock source for its operation will be
disabled in Sleep mode.
The device will wake-up from Sleep mode on any of
these events:
• On any interrupt source that is individually
enabled
• On any form of device Reset
• On a WDT time-out
On wake-up from Sleep, the processor will restart with
the same clock source that was active when Sleep
mode was entered.
10.3.1
LOW-VOLTAGE/RETENTION SLEEP
MODE
Low-Voltage/Retention Sleep mode functions as Sleep
mode, with the same features and wake-up triggers.
The difference is that the low-voltage/retention regulator allows Core Digital Logic Voltage (VCORE) to drop to
1.2V nominal. This permits an incremental reduction of
power consumption over what would be required if
VCORE was maintained at a 1.8V (minimum) level.
Low-Voltage Sleep mode requires a longer wake-up
time than Sleep mode due to the additional time
required to bring VCORE back to 1.8V (known as TREG).
In addition, the use of the low-voltage/retention regulator limits the amount of current that can be sourced to
any active peripherals, such as the RTCC, LCD, etc.
пѓЈ 2012-2014 Microchip Technology Inc.
PIC24FJ128GC010 FAMILY
10.4
Deep Sleep Mode
Deep Sleep mode provides the lowest levels of power
consumption available from the instruction-based
modes. PIC24FJ128GC010 family devices have two
Deep Sleep modes: Legacy Deep Sleep, found in other
PIC24F devices, and Retention Deep Sleep, described
below.
Deep Sleep modes have these features:
• The system clock source is shut down. If an
on-chip oscillator is used, it is turned off.
• The device current consumption will be reduced
to a minimum.
• The I/O pin directions and states are frozen.
• The Fail-Safe Clock Monitor does not operate
during Sleep mode since the system clock source
is disabled.
• The LPRC clock will continue to run in Deep
Sleep mode if the WDT, or RTCC with LPRC as
the clock source, is enabled.
• The dedicated Deep Sleep WDT and BOR
systems, if enabled, are used.
• The RTCC and its clock source continue to run if
enabled. All other peripherals are disabled.
10.4.2
Deep Sleep mode is entered by setting the DSEN bit in
the DSCON register and then executing a Sleep
command (PWRSAV #SLEEP_MODE) within one instruction cycle to minimize the chance that Deep Sleep will
be spuriously entered. If the low-voltage/retention
regulator is already enabled prior to setting the DSEN
bit, the device will enter Retention Deep Sleep.
If the PWRSAV command is not given within one
instruction cycle, the DSEN bit will be cleared by the
hardware and must be set again by the software before
entering Deep Sleep mode. The DSEN bit is also
automatically cleared when exiting Deep Sleep mode.

10.4.1
RETENTION DEEP SLEEP
5.
Unlike Deep Sleep mode, Retention Deep Sleep mode
represents an incremental increase in power consumption. Although it also allows the device to operate at a
VCORE of 1.2V, the low-voltage/retention regulator is
used in this mode to maintain the contents of the data
RAM, which slightly increases current consumption.
Maintaining data RAM (including the SFRs) has several effects that make Retention Deep Sleep different
form Deep Sleep:
• The wake-up sources are the same as those for
Deep Sleep mode.
• Wake-up from Retention Deep Sleep allows the
device to resume its previous state and start code
execution where it left off, instead of restarting at
the Reset vector (as with Deep Sleep).
пѓЈ 2012-2014 Microchip Technology Inc.
To re-enter Deep Sleep after a Deep Sleep
wake-up, allow a delay of at least 3 TCY
after clearing the RELEASE bit.
The sequence to enter Deep Sleep mode is:
Entry into Deep Sleep mode is completely under
software control. Exit from the Deep Sleep modes can
be triggered from any of the following events:
POR event
MCLR event
RTCC alarm (if the RTCC is present)
External Interrupt 0
Deep Sleep Watchdog Timer (DSWDT) time-out
ENTERING DEEP SLEEP MODE
If the application requires the Deep Sleep WDT,
enable it and configure its clock source. For
more information on Deep Sleep WDT, see
Section 10.4.6 “Deep Sleep WDT”.
If the application requires Deep Sleep BOR,
enable it by programming the DSBOREN
Configuration bit (CW4<6>).
If the application requires wake-up from Deep
Sleep on RTCC alarm, enable and configure the
RTCC module. For more information on RTCC,
see Section 23.0 “Real-Time Clock and
Calendar (RTCC)”.
If needed, save any critical application context
data by writing it to the DSGPR0 and DSGPR1
registers (optional).
Enable Deep Sleep mode by setting the DSEN
bit (DSCON<15>) twice.
Note:
6.
A repeat sequence is required to set the
DSEN bit. The repeat sequence (repeating
the instruction twice) is required to write to
any of the Deep Sleep registers (DSCON,
DSWAKE, DSGPR0, DSGPR1). This is
required to prevent the user from entering
Deep Sleep by mistake. Any write to these
registers has to be done twice to actually
complete the write (see Example 10-2).
Enter Deep Sleep mode by issuing a PWRSAV #0
instruction.
DS30009312C-page 175
PIC24FJ128GC010 FAMILY
Any time the DSEN bit is set, all bits in the DSWAKE
register will be automatically cleared.

10.4.3
EXITING DEEP SLEEP MODES
Deep Sleep modes exit on any one of the following events:
• POR event on VDD supply. If there is no DSBOR
circuit to re-arm the VDD supply POR circuit, the
external VDD supply must be lowered to the
natural arming voltage of the POR circuit.
• DSWDT time-out. When the DSWDT timer times
out, the device exits Deep Sleep.
• RTCC alarm (if RTCEN = 1).
• Assertion (�0’) of the MCLR pin.
• Assertion of the INT0 pin (if the interrupt was
enabled before Deep Sleep mode was entered).
The polarity configuration is used to determine the
assertion level (�0’ or �1’) of the pin that will cause
an exit from Deep Sleep mode. Exiting from Deep
Sleep mode requires a change on the INT0 pin
while in Deep Sleep mode.
Note:
Any interrupt pending when entering
Deep Sleep mode is cleared.
Exiting Deep Sleep generally does not retain the state
of the device and is equivalent to a Power-on Reset
(POR) of the device. Exceptions to this include the
RTCC (if present), which remains operational through
the wake-up, the DSGPRx registers and DSWDT.
Wake-up events that occur from the time Deep Sleep
exits until the time the POR sequence completes are
not ignored. The DSWAKE register will capture ALL
wake-up events, from setting DSEN to clearing
RELEASE.
DS30009312C-page 176
3.
4.
5.
6.
After a wake-up event, the device exits Deep
Sleep and performs a POR. If Retention Deep
Sleep is enabled, execution starts at the next
address for all sources but MCLR. An assertion
of MCLR will always start execution at the Reset
vector. The DSEN bit is cleared automatically.
To determine if the device exited Deep Sleep,
read the Deep Sleep bit, DPSLP (RCON<10>).
This bit will be set if there was an exit from Deep
Sleep mode. If the bit is set, clear it.
Determine the wake-up source by reading the
DSWAKE register.
Determine if a DSBOR event occurred during
Deep Sleep mode by reading the DSBOR bit
(DSCON<1>).
If application context data has been saved, read
it back from the DSGPR0 and DSGPR1 registers.
Clear the RELEASE bit (DSCON<0>).
10.4.4
SAVING CONTEXT DATA WITH THE
DSGPRx REGISTERS
As exiting Deep Sleep mode causes a POR, most
Special Function Registers reset to their default POR
values. In addition, because VCORE power is not supplied in Deep Sleep mode, information in data RAM
may be lost when exiting this mode.
Applications which require critical data to be saved,
prior to Deep Sleep, may use the Deep Sleep General
Purpose registers, DSGPR0 and DSGPR1, or data
EEPROM (if available). Unlike other SFRs, the contents of these registers are preserved while the device
is in Deep Sleep mode. After exiting Deep Sleep,
software can restore the data by reading the registers
and clearing the RELEASE bit (DSCON<0>).
10.4.5
I/O PINS IN DEEP SLEEP MODES
During Deep Sleep, the general purpose I/O pins retain
their previous states and the Secondary Oscillator
(SOSC) will remain running if enabled. Pins that are
configured as inputs (TRISx bit is set) prior to entry into
Deep Sleep remain high-impedance during Deep Sleep.
Pins that are configured as outputs (TRISx bit is clear)
prior to entry into Deep Sleep remain as output pins
during Deep Sleep. While in this mode, they continue to
drive the output level determined by their corresponding
LATx bit at the time of entry into Deep Sleep.
пѓЈ 2012-2014 Microchip Technology Inc.
PIC24FJ128GC010 FAMILY
Once the device wakes back up, all I/O pins continue to
maintain their previous states, even after the device
has finished the POR sequence and is executing
application code again. Pins configured as inputs
during Deep Sleep remain high-impedance and pins
configured as outputs continue to drive their previous
value. After waking up, the TRISx and LATx registers,
and the SOSCEN bit (OSCCON<1>), are reset. If
firmware modifies any of these bits or registers, the I/O
will not immediately go to the newly configured states.
Once the firmware clears the RELEASE bit
(DSCON<0>), the I/O pins are “released”. This causes
the I/O pins to take the states configured by their
respective TRISx and LATx bit values.
This means that keeping the SOSC running after
waking up requires the SOSCEN bit to be set before
clearing RELEASE.
If the Deep Sleep BOR (DSBOR) is enabled and a
DSBOR or a true POR event occurs during Deep
Sleep, the I/O pins will be immediately released, similar
to clearing the RELEASE bit. All previous state
information will be lost, including the general purpose
DSGPR0 and DSGPR1 contents.
If a MCLR Reset event occurs during Deep Sleep, the
DSGPRx, DSCON and DSWAKE registers will remain
valid, and the RELEASE bit will remain set. The state
of the SOSC will also be retained. The I/O pins,
however, will be reset to their MCLR Reset state. Since
RELEASE is still set, changes to the SOSCEN bit
(OSCCON<1>) cannot take effect until the RELEASE
bit is cleared.
In all other Deep Sleep wake-up cases, application
firmware must clear the RELEASE bit in order to
reconfigure the I/O pins.
10.4.6
DEEP SLEEP WDT
To enable the DSWDT in Deep Sleep mode, program
the Configuration bit, DSWDTEN (CW4<7>). The
device WDT need not be enabled for the DSWDT to
function. Entry into Deep Sleep modes automatically
resets the DSWDT.
The DSWDT clock source is selected by the
DSWDTOSC Configuration bit (CW4<5>). The postscaler
options are programmed by the DSWDPS<4:0> Configuration bits (CW4<4:0>). The minimum time-out period that
can be achieved is 1 ms and the maximum is 25.7 days.
For more details on DSWDT configuration options, refer
to Section 34.0 “Special Features”.

Both the RTCC and the DSWDT may run from either
SOSC or the LPRC clock source. This allows both the
RTCC and DSWDT to run without requiring both the
LPRC and SOSC to be enabled together, reducing
power consumption.
Running the RTCC from LPRC will result in a loss of
accuracy in the RTCC, of approximately 5 to 10%. If a
more accurate RTCC is required, it must be run from the
SOSC clock source. The RTCC clock source is selected
with the RTCLK<1:0> bits (RTCPWC<11:10>).
Under certain circumstances, it is possible for the
DSWDT clock source to be off when entering Deep
Sleep mode. In this case, the clock source is turned on
automatically (if DSWDT is enabled) without the need
for software intervention. However, this can cause a
delay in the start of the DSWDT counters. In order to
avoid this delay when using SOSC as a clock source,
the application can activate SOSC prior to entering
Deep Sleep mode.
10.4.7
CHECKING AND CLEARING THE
STATUS OF DEEP SLEEP
Upon entry into Deep Sleep mode, the status bit,
DPSLP (RCON<10>), becomes set and must be
cleared by the software.
On power-up, the software should read this status bit to
determine if the Reset was due to an exit from Deep
Sleep mode and clear the bit if it is set. Of the four
possible combinations of DPSLP and POR bit states,
three cases can be considered:
• Both the DPSLP and POR bits are cleared. In this
case, the Reset was due to some event other
than a Deep Sleep mode exit.
• The DPSLP bit is clear, but the POR bit is set; this
is a normal POR.
• Both the DPSLP and POR bits are set. This
means that Deep Sleep mode was entered, the
device was powered down and Deep Sleep mode
was exited.
10.4.8
POWER-ON RESETS (PORs)
VDD voltage is monitored to produce PORs. Since
exiting from Deep Sleep mode functionally looks like a
POR, the technique described in Section 10.4.7
“Checking and Clearing the Status of Deep Sleep”
should be used to distinguish between Deep Sleep and
a true POR event. When a true POR occurs, the entire
device, including all Deep Sleep logic (Deep Sleep
registers, RTCC, DSWDT, etc.), is reset.

10.5
VBAT Mode
This mode represents the lowest power state that the
microcontroller can achieve and still resume operation.
VBAT mode is automatically triggered when the microcontroller’s main power supply on VDD fails. When this
happens, the microcontroller’s on-chip power switch
connects to a backup power source, such as a battery
supplied to the VBAT pin. This maintains a few key
systems at an extremely low-power draw until VDD is
restored.
The power supplied on VBAT only runs two systems:
the RTCC and the Deep Sleep Semaphore Data
registers (DSGPR0 and DSGPR1). To maintain these
systems during a sudden loss of VDD, it is essential to
connect a power source, other than VDD or AVDD, to the
VBAT pin.
When the RTCC is enabled, it continues to operate with
the same clock source (SOSC or LPRC) that was
selected prior to entering VBAT mode. There is no provision to switch to a lower power clock source after the
mode switch.
To differentiate a wake-up from VBAT mode from other
POR states, check the VBAT status bit (RCON2<0>). If
this bit is set while the device is starting to execute the
code from the Reset vector, it indicates that there has
been an exit from VBAT mode. The application must
clear the VBAT bit to ensure that future VBAT wake-up
events are captured.
If a POR occurs without a power source connected to
the VBAT pin, the VBPOR bit (RCON2<1>) is set. If this
bit is set on a POR, it indicates that a battery needs to
be connected to the VBAT pin.
In addition, if the VBAT power source falls below the
level needed for Deep Sleep semaphore operation
while in VBAT mode (e.g., the battery has been
drained), the VBPOR bit will be set. VBPOR is also set
when the microcontroller is powered up the very first
time, even if power is supplied to VBAT.
10.5.3
I/O PINS DURING VBAT MODES
Since the loss of VDD is usually an unforeseen event, it
is recommended that the contents of the Deep Sleep
Semaphore Data registers be loaded with the data to
be retained at an early point in code execution.
All I/O pins switch to Input mode during VBAT mode.
The only exceptions are the SOSCI and SOSCO pins,
which maintain their states if the Secondary Oscillator
is being used as the RTCC clock source. It is the user’s
responsibility to restore the I/O pins to their proper
states using the TRISx and LATx bits once VDD has
been restored.
10.5.1
10.5.4
VBAT MODE WITH NO RTCC
By disabling RTCC operation during VBAT mode,
power consumption is reduced to the lowest of all
power-saving modes. This is done by programming the
RTCBAT Configuration bit (CW4<9>) to �0’. In this
mode, only the Deep Sleep Semaphore Data registers
are maintained.
10.5.2
WAKE-UP FROM VBAT MODES
When VDD is restored to a device in VBAT mode, it automatically wakes. Wake-up occurs with a POR, after
which, the device starts executing code from the Reset
vector. All SFRs, except the Deep Sleep Semaphore
Data registers, are reset to their POR values. If the
RTCC was not configured to run during VBAT mode, it
will remain disabled and RTCC will not run. Wake-up
timing is similar to that for a normal POR.
DS30009312C-page 178
SAVING CONTEXT DATA WITH THE
DSGPRx REGISTERS
As with Deep Sleep mode (i.e., without the
low-voltage/retention regulator), all SFRs are reset to
their POR values after VDD has been restored. Only the
Deep Sleep Semaphore Data registers are preserved.
Applications which require critical data to be saved
should save it in DSGPR0 and DSGPR1.
Note:
If the VBAT mode is not used, it is
recommended to connect the VBAT pin
to VDD.
The POR should be enabled for the reliable operation
of the VBAT.

10.6
Clock Frequency and Clock
Switching
In Run and Idle modes, all PIC24F devices allow for a
wide range of clock frequencies to be selected under
application control. If the system clock configuration
is not locked, users can choose low-power or
high-precision oscillators by simply changing the
NOSCx bits. The process of changing a system clock
during operation, as well as limitations to the process,
are discussed in more detail in Section 9.0 “Oscillator
Configuration”.
10.7
Doze Mode
Generally, changing clock speed and invoking one of
the power-saving modes are the preferred strategies
for reducing power consumption. There may be circumstances, however, where this is not practical. For
example, it may be necessary for an application to
maintain uninterrupted synchronous communication,
even while it is doing nothing else. Reducing system
clock speed may introduce communication errors,
while using a power-saving mode may stop
communications completely.
Doze mode is a simple and effective alternative method
to reduce power consumption while the device is still
executing code. Peripheral modules continue to be
clocked at the same speed, while the CPU clock speed
is reduced. Synchronization between the two clock
domains is maintained, allowing the peripherals to
access the SFRs while the CPU executes code at a
slower rate.
Doze mode is enabled by setting the DOZEN bit
(CLKDIV<11>). The ratio between peripheral and
core clock speed is determined by the DOZE<2:0>
bits (CLKDIV<14:12>). There are eight possible
configurations, from 1:1 to 1:128, with 1:8 being the
default. A ratio setting of 1:8 means the CPU is running
at 1/8th the frequency of the peripherals.
It is also possible to use Doze mode to selectively reduce
power consumption in event driven applications. This
allows clock-sensitive functions, such as synchronous
communications, to continue without interruption while
the CPU Idles, waiting for something to invoke an interrupt routine. Enabling the automatic return to full-speed
CPU operation on interrupts is enabled by setting the
ROI bit (CLKDIV<15>). By default, interrupt events have
no effect on Doze mode operation.
DS30009312C-page 182
Operations that immediately follow any manipulations
of the DOZE<2:0> or DOZEN bits (CLKDIV<14:11>)
should not perform any SFR or data RAM reads or
writes as it can result in incorrect results. As a result,
any time the DOZEx or DOZEN bits are modified, a
NOP instruction should be manually inserted before and
after the instructions modifying these bits, as shown in
Example 10-3.
EXAMPLE 10-3:
ENTERING/EXITING DOZE
Entering Doze Mode:
NOP();
OSCCONbits.DOZEN = 1;
NOP();
Exiting Doze Mode:
NOP();
OSCCONbits.DOZEN = 0;
NOP();
10.8
Selective Peripheral Module
Control
Idle and Doze modes allow users to substantially
reduce power consumption by slowing the CPU clock.
Even so, peripheral modules still remain clocked, and
thus, consume power. Setting the disable bit in a
peripheral module will still cause that peripheral to draw
some quiescent current. Since most applications do not
need every peripheral in the chip, there is a mechanism
for physically shutting the clocks off to every selected
peripheral, thereby reducing the overall current drain of
the chip.
PIC24F devices address this requirement by allowing
peripheral modules to be selectively disabled, reducing
or eliminating their power consumption. This can be
done with two control bits:
• The Peripheral Enable bit, generically named,
“XXXEN”, located in the module’s main control
SFR.
• The Peripheral Module Disable (PMD) bit,
generically named, “XXXMD”, located in one of
the PMDx Control registers (XXXMD bits are in
the PMDx registers shown in Table 4-39).
пѓЈ 2012-2014 Microchip Technology Inc.
PIC24FJ128GC010 FAMILY
Both bits have similar functions in enabling or disabling
its associated module. Setting the PMDx bit for a module
disables all clock sources to that module, reducing its
power consumption to an absolute minimum. In this
state, the control and status registers associated with the
peripheral will also be disabled, so writes to those
registers will have no effect and read values will be
invalid. Most peripheral modules have a corresponding
PMDx bit.
The POR default sets all PMDx bits to �0’ so that every
peripheral is clocked. This means the chip will POR to
the maximum power consumption. If the application
does not use some peripherals, setting unused peripheral PMDx bits will reduce the overall power
consumption. Note that there is a small delay time (on
the order of 10 ВµS) for the peripheral to initialize after
being disabled, then enabled by clearing the PMDx bit.
Application software must take this delay into account
so that the peripheral has time to initialize before use.
пѓЈ 2012-2014 Microchip Technology Inc.
In contrast, disabling a module by clearing its XXXEN
bit disables its functionality, but leaves its registers
available to be read and written to. Power consumption
is reduced, but not by as much as when the PMDx bits
are used. Most peripheral modules have an enable bit;
exceptions include capture, compare and RTCC.
To achieve more selective power savings, peripheral
modules can also be selectively disabled when the
device enters Idle mode. This is done through the control
bit of the generic name format, “XXXIDL”. By default, all
modules that can operate during Idle mode will do so.
Using the disable on Idle feature disables the module
while in Idle mode, allowing further reduction of power
consumption during Idle mode, enhancing power
savings for extremely critical power applications.

Note:
I/O PORTS
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “I/O Ports with Peripheral Pin
Select (PPS)” (DS39711). The information
in this data sheet supersedes the information in the FRM.
All of the device pins (except VDD, VSS, MCLR and
OSCI/CLKI) are shared between the peripherals and
the Parallel I/O ports. All I/O input ports feature Schmitt
Trigger (ST) inputs for improved noise immunity.
11.1
Parallel I/O (PIO) Ports
A Parallel I/O port that shares a pin with a peripheral is,
in general, subservient to the peripheral. The peripheral’s output buffer data and control signals are
provided to a pair of multiplexers. The multiplexers
select whether the peripheral or the associated port
has ownership of the output data and control signals of
the I/O pin. The logic also prevents “loop through”, in
which a port’s digital output can drive the input of a
peripheral that shares the same pin. Figure 11-1 shows
how ports are shared with other peripherals and the
associated I/O pin to which they are connected.
FIGURE 11-1:
When a peripheral is enabled and the peripheral is
actively driving an associated pin, the use of the pin as
a general purpose output pin is disabled. The I/O pin
may be read, but the output driver for the parallel port
bit will be disabled. If a peripheral is enabled, but the
peripheral is not actively driving a pin, that pin may be
driven by a port.
All port pins have three registers directly associated
with their operation as digital I/O and one register associated with their operation as analog inputs. The Data
Direction register (TRISx) determines whether the pin
is an input or an output. If the data direction bit is a �1’,
then the pin is an input. All port pins are defined as
inputs after a Reset. Reads from the Output Latch register (LATx), read the latch; writes to the latch, write the
latch. Reads from the port (PORTx), read the port pins;
writes to the port pins, write the latch.
Any bit and its associated data and control registers
that are not valid for a particular device will be
disabled. That means the corresponding LATx and
TRISx registers, and the port pin will read as zeros.
When a pin is shared with another peripheral or function that is defined as an input only, it is regarded as a
dedicated port because there is no other competing
source of inputs. RC13 and RC14 can be input ports
only; they cannot be configured as outputs.

11.1.1
I/O PORT WRITE/READ TIMING
11.2
One instruction cycle is required between a port direction
change or port write operation and a read operation of
the same port. Typically, this instruction would be a NOP.
11.1.2
OPEN-DRAIN CONFIGURATION
In addition to the PORTx, LATx and TRISx registers for
data control, each port pin can also be individually
configured for either a digital or open-drain output. This
is controlled by the Open-Drain Control register, ODCx,
associated with each port. Setting any of the bits
configures the corresponding pin to act as an
open-drain output.
The open-drain feature allows the generation of
outputs higher than VDD (e.g., 5V) on any desired
digital only pins by using external pull-up resistors. The
maximum open-drain voltage allowed is the same as
the maximum VIH specification.
11.1.3
GPIO FUNCTIONS ON THE USB PINS
When the USB module is enabled, the USB module
controls the RG2/RG3/RF7 port pins. General purpose
input/output and related interrupt-on-change functionality can be made available on the RG2/RG3/RF7 pins
when the USB module is disabled and the UTRDIS
(U1CNFG2<0>) bit is set. Additionally, for general
purpose digital input function on RF7/VBUS, the ANSF7
bit must be cleared.
TABLE 11-1:
Configuring Analog Port Pins
(ANSx)
The ANSx and TRISx registers control the operation of
the pins with analog function. Each port pin with analog
function is associated with one of the ANSx bits (see
Register 11-1 through Register 11-7), which decides if
the pin function should be analog or digital. Refer to
Table 11-1 for detailed behavior of the pin for different
ANSx and TRISx bit settings.
When reading the PORTx register, all pins configured as
analog input channels will read as cleared (a low level).
11.2.1
ANALOG INPUT PINS AND
VOLTAGE CONSIDERATIONS
The voltage tolerance of pins used as device inputs is
dependent on the pin’s input function. Most input pins are
able to handle DC voltages of up to 5.5V, a level typical
for digital logic circuits. However, several pins can only
tolerate voltages up to VDD. Voltage excursions beyond
VDD on these pins should always be avoided.
Table 11-2 summarizes the different voltage tolerances.

Input Change Notification (ICN)
The Input Change Notification function of the I/O ports
allows the PIC24FJ128GC010 family of devices to generate interrupt requests to the processor in response to
a Change-of-State (COS) on selected input pins. This
feature is capable of detecting input Change-of-States,
even in Sleep mode, when the clocks are disabled.
Depending on the device pin count, there are up to
82 external inputs that may be selected (enabled) for
generating an interrupt request on a Change-of-State.
Registers, CNEN1 through CNEN6, contain the interrupt
enable control bits for each of the Change Notification
(CN) input pins. Setting any of these bits enables a CN
interrupt for the corresponding pins.
Each CN pin has both a weak pull-up and a weak
pull-down connected to it. The pull-ups act as a current
source that is connected to the pin, while the pull-downs
act as a current sink that is connected to the pin. These
eliminate the need for external resistors when push button or keypad devices are connected. The pull-ups and
pull-downs are separately enabled using the CNPU1
through CNPU6 registers (for pull-ups) and the CNPD1
through CNPD6 registers (for pull-downs). Each CN pin
has individual control bits for its pull-up and pull-down.
Setting a control bit enables the weak pull-up or
pull-down for the corresponding pin.
When the internal pull-up is selected, the pin pulls up to
VDD – 1.1V (typical). When the internal pull-down is
selected, the pin pulls down to VSS.

11.4
Peripheral Pin Select (PPS)
A major challenge in general purpose devices is providing the largest possible set of peripheral features while
minimizing the conflict of features on I/O pins. In an
application that needs to use more than one peripheral
multiplexed on a single pin, inconvenient work arounds
in application code, or a complete redesign, may be the
only option.
The Peripheral Pin Select (PPS) feature provides an
alternative to these choices by enabling the user’s
peripheral set selection and its placement on a wide
range of I/O pins. By increasing the pinout options
available on a particular device, users can better tailor
the microcontroller to their entire application, rather
than trimming the application to fit the device.
The Peripheral Pin Select feature operates over a fixed
subset of digital I/O pins. Users may independently
map the input and/or output of any one of many digital
peripherals to any one of these I/O pins. PPS is performed in software and generally does not require the
device to be reprogrammed. Hardware safeguards are
included that prevent accidental or spurious changes to
the peripheral mapping once it has been established.
11.4.1
AVAILABLE PINS
The PPS feature is used with a range of up to 44 pins,
depending on the particular device and its pin count.
Pins that support the Peripheral Pin Select feature
include the designation, “RPn” or “RPIn”, in their full pin
designation, where “n” is the remappable pin number.
“RP” is used to designate pins that support both remappable input and output functions, while “RPI” indicates
pins that support remappable input functions only.
PIC24FJ128GC010 family devices support a larger
number of remappable input only pins than remappable
input/output pins. In this device family, there are up to
32 remappable input/output pins, depending on the pin
count of the particular device selected. These pins are
numbered, RP0 through RP31. Remappable input only
pins are numbered above this range, from RPI32 to
RPI43 (or the upper limit for that particular device).
See Table 1-3 for a summary of pinout options in each
package offering.
11.4.2
AVAILABLE PERIPHERALS
The peripherals managed by the PPS are all digital
only peripherals. These include general serial communications (UART and SPI), general purpose timer clock
inputs, timer related peripherals (input capture and
output compare) and external interrupt inputs. Also
included are the outputs of the comparator module,
since these are discrete digital signals.

A key difference between pin select and non-pin select
peripherals is that pin select peripherals are not associated with a default I/O pin. The peripheral must
always be assigned to a specific I/O pin before it can be
used. In contrast, non-pin select peripherals are always
available on a default pin, assuming that the peripheral
is active and not conflicting with another peripheral.
11.4.2.1
Peripheral Pin Select Function
Priority
Pin-selectable peripheral outputs (e.g., OC, UART
transmit) will take priority over general purpose digital
functions on a pin, such as EPMP and port I/O. Specialized digital outputs (e.g., USB on USB-enabled devices)
will take priority over PPS outputs on the same pin. The
pin diagrams list peripheral outputs in the order of priority. Refer to them for priority concerns on a particular
pin.
Unlike PIC24F devices with fixed peripherals,
pin-selectable peripheral inputs will never take ownership of a pin. The pin’s output buffer will be controlled
by the TRISx setting or by a fixed peripheral on the pin.
If the pin is configured in Digital mode, then the PPS
input will operate correctly. If an analog function is
enabled on the pin, the PPS input will be disabled.
11.4.3
CONTROLLING PERIPHERAL PIN
SELECT
PPS features are controlled through two sets of Special
Function Registers (SFRs): one to map peripheral
inputs and one to map the outputs. Because they are
separately controlled, a particular peripheral’s input
and output (if the peripheral has both) can be placed on
any selectable function pin without constraint.
The association of a peripheral to a peripheral-selectable
pin is handled in two different ways, depending on if an
input or an output is being mapped.

11.4.3.1
Input Mapping
The inputs of the Peripheral Pin Select options are
mapped on the basis of the peripheral; that is, a control
register associated with a peripheral dictates the pin it
will be mapped to. The RPINRx registers are used to
configure peripheral input mapping (see Register 11-9
through Register 11-27).
TABLE 11-3:
Each register contains two sets of 6-bit fields, with each
set associated with one of the pin-selectable peripherals. Programming a given peripheral’s bit field with an
appropriate 6-bit value maps the RPn/RPIn pin with
that value to that peripheral. For any given device, the
valid range of values for any of the bit fields corresponds to the maximum number of Peripheral Pin
Selections supported by the device.

Output Mapping
corresponds to one of the peripherals and that
peripheral’s output is mapped to the pin (see
Table 11-4).
In contrast to inputs, the outputs of the Peripheral Pin
Select options are mapped on the basis of the pin. In
this case, a control register associated with a particular
pin dictates the peripheral output to be mapped. The
RPORx registers are used to control output mapping.
Each register contains two 6-bit fields, with each field
being associated with one RPn pin (see Register 11-28
through Register 11-43). The value of the bit field
TABLE 11-4:
Because of the mapping technique, the list of peripherals for output mapping also includes a null value of
�000000’. This permits any given pin to remain disconnected from the output of any of the pin-selectable
peripherals.

Mapping Limitations
• Configuration bit remapping lock
The control schema of the Peripheral Pin Select is
extremely flexible. Other than systematic blocks that
prevent signal contention, caused by two physical pins
being configured as the same functional input or two
functional outputs configured as the same pin, there
are no hardware enforced lockouts. The flexibility
extends to the point of allowing a single input to drive
multiple peripherals or a single functional output to
drive multiple output pins.
11.4.4.1
11.4.3.4

To change the PPS registers, they must be unlocked in
hardware. The register lock is controlled by the
IOLOCK bit (OSCCON<6>). Setting IOLOCK prevents
writes to the control registers; clearing IOLOCK allows
writes. The POR state of the PPS registers is unlocked.
To set or clear IOLOCK, a specific command sequence
must be executed:
Mapping Exceptions for
PIC24FJ128GC010 Family Devices
Although the PPS registers theoretically allow for up to
64 remappable I/O pins, not all of these are implemented in all devices. For PIC24FJ128GC010 family
devices, the maximum number of remappable pins
available is 44, which includes 12 input only pins. In
addition, some pins in the RP and RPI sequences are
unimplemented in lower pin count devices. The
differences in available remappable pins are
summarized in Table 11-5.
11.4.4.2
Continuous State Monitoring
In addition to being protected from direct writes while
locked, the contents of the RPINRx and RPORx registers are constantly monitored in hardware by shadow
registers. If an unexpected change in any of the registers occurs (such as cell disturbances caused by ESD
or other external events), a Configuration Mismatch
Reset will be triggered.
• For the RPINRx registers, bit combinations corresponding to an unimplemented pin for a particular
device are treated as invalid; the corresponding
module will not have an input mapped to it. For all
PIC24FJ128GC010 family devices, this includes
all values greater than 43 (�101011’).
• For RPORx registers, the bit fields corresponding
to an unimplemented pin will also be
unimplemented. Writing to these fields will have
no effect.
11.4.4.3
Configuration Bit Pin Select Lock
As an additional level of safety, the device can be configured to prevent more than one write session to the
RPINRx and RPORx registers. The IOL1WAY Configuration bit (CW4<15>) blocks the IOLOCK bit from being
cleared after it has been set once. If IOLOCK remains
set, the register unlock procedure will not execute and
the Peripheral Pin Select Control registers cannot be
written to. The only way to clear the bit and re-enable
peripheral remapping is to perform a device Reset.
CONTROLLING CONFIGURATION
CHANGES
Because peripheral remapping can be changed during
run time, some restrictions on peripheral remapping
are needed to prevent accidental configuration
changes. PIC24F devices include three features to
prevent alterations to the peripheral map:
In the default (unprogrammed) state, IOL1WAY is set,
restricting users to one write session. Programming
IOL1WAY allows users unlimited access (with the
proper use of the unlock sequence) to the Peripheral
Pin Select registers.
• Control register lock sequence
• Continuous state monitoring
TABLE 11-5:
Write 46h to OSCCON<7:0>.
Write 57h to OSCCON<7:0>.
Clear (or set) IOLOCK as a single operation.
Unlike the similar sequence with the oscillator’s LOCK
bit, IOLOCK remains in one state until changed. This
allows all of the Peripheral Pin Selects to be configured
with a single unlock sequence, followed by an update
to all control registers, then locked with a second lock
sequence.
When developing applications that use remappable
pins, users should also keep these things in mind:

CONSIDERATIONS FOR
PERIPHERAL PIN SELECTION
The ability to control Peripheral Pin Selection introduces several considerations into application design
that could be overlooked. This is particularly true for
several common peripherals that are available only as
remappable peripherals.
The main consideration is that the Peripheral Pin Selects
are not available on default pins in the device’s default
(Reset) state. Since all RPINRx registers reset to
�111111’, and all RPORx registers reset to �000000’, all
Peripheral Pin Select inputs are tied to VSS and all
Peripheral Pin Select outputs are disconnected.
Note:
In tying Peripheral Pin Select inputs to
RP63, the RP63 pin need not exist on a
device for the registers to be reset to it.
This situation requires the user to initialize the device
with the proper peripheral configuration before any
other application code is executed. Since the IOLOCK
bit resets in the unlocked state, it is not necessary to
execute the unlock sequence after the device has
come out of Reset. For application safety, however, it is
best to set IOLOCK and lock the configuration after
writing to the control registers.
Because the unlock sequence is timing-critical, it must
be executed as an assembly language routine in the
same manner as changes to the oscillator configuration. If the bulk of the application is written in �C’, or
another high-level language, the unlock sequence
should be performed by writing in-line assembly.
Choosing the configuration requires a review of all
Peripheral Pin Selects and their pin assignments,
especially those that will not be used in the application.
In all cases, unused pin-selectable peripherals should
be disabled completely. Unused peripherals should
have their inputs assigned to an unused RPn/RPIn pin
function. I/O pins with unused RPn functions should be
configured with the null peripheral output.
The assignment of a peripheral to a particular pin does
not automatically perform any other configuration of the
pin’s I/O circuitry. In theory, this means adding a
pin-selectable output to a pin may mean inadvertently
driving an existing peripheral input when the output is
driven. Users must be familiar with the behavior of
other fixed peripherals that share a remappable pin and
know when to enable or disable them. To be safe, fixed
digital peripherals that share the same pin should be
disabled when not in use.
Along these lines, configuring a remappable pin for a
specific peripheral does not automatically turn that
feature on. The peripheral must be specifically configured for operation and enabled as if it were tied to a
fixed pin. Where this happens in the application code
(immediately following a device Reset and peripheral
configuration or inside the main application routine)
depends on the peripheral and its use in the
application.
A final consideration is that Peripheral Pin Select functions neither override analog inputs nor reconfigure
pins with analog functions for digital I/O. If a pin is
configured as an analog input on device Reset, it must
be explicitly reconfigured as digital I/O when used with
a Peripheral Pin Select.
Example 11-3 shows a configuration for bidirectional
communication with flow control using UART1. The
following input and output functions are used:
• Input Functions: U1RX, U1CTS
• Output Functions: U1TX, U1RTS

2.
3.
4.
The Timer1 module is a 16-bit timer, which can serve
as the time counter for the Real-Time Clock (RTC) or
operate as a free-running, interval timer/counter.
Timer1 can operate in three modes:
• 16-Bit Timer
• 16-Bit Synchronous Counter
• 16-Bit Asynchronous Counter
5.
6.
Set the TON bit (= 1).
Select the timer prescaler ratio using the
TCKPS<1:0> bits.
Set the Clock and Gating modes using the TCS,
TIECS<1:0> and TGATE bits.
Set or clear the TSYNC bit to configure
synchronous or asynchronous operation.
Load the timer period value into the PR1
register.
If interrupts are required, set the Timer1 Interrupt
Enable bit, T1IE. Use the Timer1 Interrupt Priority
bits, T1IP<2:0>, to set the interrupt priority.
Timer1 also supports these features:
•
•
•
•
Timer Gate Operation
Selectable Prescaler Settings
Timer Operation During CPU Idle and Sleep modes

TIMER2/3 AND TIMER4/5
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “Timers” (DS39704). The information in this data sheet supersedes the
information in the FRM.
The Timer2/3 and Timer4/5 modules are 32-bit timers,
which can also be configured as four independent, 16-bit
timers with selectable operating modes.
To configure Timer2/3 or Timer4/5 for 32-bit operation:
1.
2.
3.
4.
As 32-bit timers, Timer2/3 and Timer4/5 can each
operate in three modes:
• Two Independent 16-Bit Timers with All 16-Bit
Operating modes (except Asynchronous Counter
mode)
• Single 32-Bit Timer
• Single 32-Bit Synchronous Counter
They also support these features:
•
•
•
•
•
Timer Gate Operation
Selectable Prescaler Settings
Timer Operation During Idle and Sleep modes
Interrupt on a 32-Bit Period Register Match
A/D Event Trigger (only on Timer2/3 in 32-bit
mode and Timer3 in 16-bit mode)
Individually, all four of the 16-bit timers can function as
synchronous timers or counters. They also offer the
features listed above, except for the A/D Event Trigger.
This trigger is implemented only on Timer2/3 in 32-bit
mode and Timer3 in 16-bit mode. The operating modes
and enabled features are determined by setting the
appropriate bit(s) in the T2CON, T3CON, T4CON and
T5CON registers. T2CON and T4CON are shown in
generic form in Register 13-1; T3CON and T5CON are
shown in Register 13-2.
For 32-bit timer/counter operation, Timer2 and Timer4
are the least significant word; Timer3 and Timer5 are
the most significant word of the 32-bit timers.
Note:
5.
6.
Set the T32 or T45 bit (T2CON<3> or
T4CON<3> = 1).
Select the prescaler ratio for Timer2 or Timer4
using the TCKPS<1:0> bits.
Set the Clock and Gating modes using the TCS
and TGATE bits. If TCS is set to an external
clock, RPINRx (TxCK) must be configured to
an available RPn/RPIn pin. For more information, see Section 11.4 “Peripheral Pin Select
(PPS)”.
Load the timer period value. PR3 (or PR5) will
contain the most significant word (msw) of the
value, while PR2 (or PR4) contains the least
significant word (lsw).
If interrupts are required, set the interrupt enable
bit, T3IE or T5IE. Use the priority bits, T3IP<2:0>
or T5IP<2:0>, to set the interrupt priority. Note
that while Timer2 or Timer4 controls the timer, the
interrupt appears as a Timer3 or Timer5 interrupt.
Set the TON bit (= 1).
The timer value, at any point, is stored in the register
pair, TMR<3:2> (or TMR<5:4>). TMR3 (TMR5) always
contains the most significant word of the count while
TMR2 (TMR4) contains the least significant word.
To configure any of the timers for individual 16-bit
operation:
1.
2.
3.
4.
5.
6.
Clear the T32 bit corresponding to that timer
(T2CON<3> for Timer2 and Timer3 or
T4CON<3> (T45) for Timer4 and Timer5).
Select the timer prescaler ratio using the
TCKPS<1:0> bits.
Set the Clock and Gating modes using the TCS
and TGATE bits. See Section 11.4 “Peripheral
Pin Select (PPS)” for more information.
Load the timer period value into the PRx register.
If interrupts are required, set the interrupt enable
bit, TxIE. Use the priority bits, TxIP<2:0>, to set
the interrupt priority.
Set the TON (TxCON<15> = 1) bit.
For 32-bit operation, the T3CON and
T5CON control bits are ignored. Only the
T2CON and T4CON control bits are used
for setup and control. Timer2 and Timer4
clock and gate inputs are utilized for the
32-bit timer modules, but an interrupt is
generated with the Timer3 or Timer5
interrupt flags.

INPUT CAPTURE WITH
DEDICATED TIMERS
Note:
14.1
14.1.1
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Input Capture with Dedicated
Timer” (DS39722). The information in this
data sheet supersedes the information in
the FRM.
Devices in the PIC24FJ128GC010 family contain
seven independent input capture modules. Each of the
modules offers a wide range of configuration and
operating options for capturing external pulse events
and generating interrupts.
Key features of the input capture module include:
• Hardware-configurable for 32-bit operation in all
modes by cascading two adjacent modules
• Synchronous and Trigger modes of output
compare operation, with up to 30 user-selectable
sync/trigger sources available
• A 4-level FIFO buffer for capturing and holding
timer values for several events
• Configurable interrupt generation
• Up to 6 clock sources available for each module,
driving a separate internal 16-bit counter
The module is controlled through two registers: ICxCON1
(Register 14-1) and ICxCON2 (Register 14-2). A general
block diagram of the module is shown in Figure 14-1.
FIGURE 14-1:
SYNCHRONOUS AND TRIGGER
MODES
When the input capture module operates in a
Free-Running mode, the internal 16-bit counter,
ICxTMR, counts up continuously, wrapping around
from FFFFh to 0000h on each overflow. Its period is
synchronized to the selected external clock source.
When a capture event occurs, the current 16-bit value
of the internal counter is written to the FIFO buffer.
In Synchronous mode, the module begins capturing
events on the ICx pin as soon as its selected clock
source is enabled. Whenever an event occurs on the
selected sync source, the internal counter is reset. In
Trigger mode, the module waits for a sync event from
another internal module to occur before allowing the
internal counter to run.
Standard, free-running operation is selected by setting
the SYNCSEL<4:0> bits (ICxCON2<4:0>) to �00000’
and clearing the ICTRIG bit (ICxCON2<7>). Synchronous and Trigger modes are selected any time the
SYNCSELx bits are set to any value except �00000’.
The ICTRIG bit selects either Synchronous or Trigger
mode; setting the bit selects Trigger mode operation. In
both modes, the SYNCSEL<4:0> bits determine the
sync/trigger source.
When the SYNCSELx bits are set to �00000’ and
ICTRIG is set, the module operates in Software Trigger
mode. In this case, capture operations are started by
manually setting the TRIGSTAT bit (ICxCON2<6>).

CASCADED (32-BIT) MODE
By default, each module operates independently with
its own 16-bit timer. To increase resolution, adjacent
even and odd modules can be configured to function as
a single 32-bit module. (For example, Modules 1 and 2
are paired, as are Modules 3 and 4, and so on.) The
odd numbered module (ICx) provides the Least Significant 16 bits of the 32-bit register pairs and the even
module (ICy) provides the Most Significant 16 bits.
Wrap-arounds of the ICx registers cause an increment
of their corresponding ICy registers.
Cascaded operation is configured in hardware by
setting the IC32 bits (ICxCON2<8>) for both modules.
14.2
Capture Operations
The input capture module can be configured to capture
timer values and generate interrupts on rising edges on
ICx or all transitions on ICx. Captures can be configured to occur on all rising edges or just some (every 4th
or 16th). Interrupts can be independently configured to
generate on each event or a subset of events.
For 32-bit cascaded operations, the setup procedure is
slightly different:
1.
2.
3.
4.
5.
Note:
To set up the module for capture operations:

2.

7.
8.
9.
Configure the ICx input for one of the available
Peripheral Pin Select pins.
If Synchronous mode is to be used, disable the
sync source before proceeding.
Make sure that any previous data has been
removed from the FIFO by reading ICxBUF until
the ICBNE bit (ICxCON1<3>) is cleared.
Set the SYNCSEL<4:0> bits (ICxCON2<4:0>)
to the desired sync/trigger source.
Set the ICTSEL<2:0> bits (ICxCON1<12:10>)
for the desired clock source.
Set the ICI<1:0> bits (ICxCON1<6:5>) to the
desired interrupt frequency
Select Synchronous or Trigger mode operation:
a) Check that the SYNCSELx bits are not set
to �00000’.
b) For Synchronous mode, clear the ICTRIG
bit (ICxCON2<7>).
c) For Trigger mode, set ICTRIG and clear the
TRIGSTAT bit (ICxCON2<6>).
Set the ICM<2:0> bits (ICxCON1<2:0>) to the
desired operational mode.
Enable the selected sync/trigger source.
DS30009312C-page 226
Set the IC32 bits for both modules (ICyCON2<8>
and ICxCON2<8>), enabling the even numbered
module first. This ensures that the modules will
start functioning in unison.
Set the ICTSELx and SYNCSELx bits for both
modules to select the same sync/trigger and time
base source. Set the even module first, then the
odd module. Both modules must use the same
ICTSELx and SYNCSELx bits settings.
Clear the ICTRIG bit of the even module
(ICyCON2<7>). This forces the module to run in
Synchronous mode with the odd module,
regardless of its trigger setting.
Use the odd module’s ICIx bits (ICxCON1<6:5>)
to set the desired interrupt frequency.
Use the ICTRIG bit of the odd module
(ICxCON2<7>) to configure Trigger or
Synchronous mode operation.
6.
For Synchronous mode operation, enable
the sync source as the last step. Both
input capture modules are held in Reset
until the sync source is enabled.
Use the ICMx bits of the odd module
(ICxCON1<2:0>) to set the desired Capture
mode.
The module is ready to capture events when the time
base and the sync/trigger source are enabled. When
the ICBNE bit (ICxCON1<3>) becomes set, at least
one capture value is available in the FIFO. Read input
capture values from the FIFO until the ICBNE clears
to �0’.
For 32-bit operation, read both the ICxBUF and
ICyBUF for the full 32-bit timer value (ICxBUF for the
lsw, ICyBUF for the msw). At least one capture value is
available in the FIFO buffer when the odd module’s
ICBNE bit (ICxCON1<3>) becomes set. Continue to
read the buffer registers until ICBNE is cleared
(performed automatically by hardware).

OUTPUT COMPARE WITH
DEDICATED TIMERS
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Output Compare with Dedicated
Timer” (DS70005159). The information in
this data sheet supersedes the information
in the FRM.
Devices in the PIC24FJ128GC010 family all feature
seven independent output compare modules. Each of
these modules offers a wide range of configuration and
operating options for generating pulse trains on internal
device events, and can produce Pulse-Width Modulated
(PWM) waveforms for driving power applications.
Key features of the output compare module include:
• Hardware-configurable for 32-bit operation in all
modes by cascading two adjacent modules
• Synchronous and Trigger modes of output
compare operation, with up to 31 user-selectable
trigger/sync sources available
• Two separate Period registers (a main register,
OCxR, and a secondary register, OCxRS) for
greater flexibility in generating pulses of varying
widths
• Configurable for single pulse or continuous pulse
generation on an output event, or continuous
PWM waveform generation
• Up to 6 clock sources available for each module,
driving a separate internal 16-bit counter
15.1
15.1.1
In Synchronous mode, the module begins performing
its compare or PWM operation as soon as its selected
clock source is enabled. Whenever an event occurs on
the selected sync source, the module’s internal counter
is reset. In Trigger mode, the module waits for a sync
event from another internal module to occur before
allowing the counter to run.
Free-Running mode is selected by default or any time
that the SYNCSEL<4:0> bits (OCxCON2<4:0>) are set
to �00000’. Synchronous or Trigger modes are selected
any time the SYNCSELx bits are set to any value except
�00000’. The OCTRIG bit (OCxCON2<7>) selects either
Synchronous or Trigger mode; setting the bit selects
Trigger mode operation. In both modes, the SYNCSELx
bits determine the sync/trigger source.
15.1.2
CASCADED (32-BIT) MODE
By default, each module operates independently with
its own set of 16-bit Timer and Duty Cycle registers. To
increase resolution, adjacent even and odd modules
can be configured to function as a single 32-bit module.
(For example, Modules 1 and 2 are paired, as are
Modules 3 and 4, and so on.) The odd numbered
module (OCx) provides the Least Significant 16 bits of
the 32-bit register pairs and the even numbered
module (OCy) provides the Most Significant 16 bits.
Wrap-arounds of the OCx registers cause an increment
of their corresponding OCy registers.
Cascaded operation is configured in hardware by setting the OC32 bit (OCxCON2<8>) for both modules.
For more details on cascading, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Output
Compare with Dedicated Timer” (DS70005159).
General Operating Modes
SYNCHRONOUS AND TRIGGER
MODES
When the output compare module operates in a
Free-Running mode, the internal 16-bit counter,
OCxTMR, runs counts up continuously, wrapping
around from 0xFFFF to 0x0000 on each overflow. Its
period is synchronized to the selected external clock
source. Compare or PWM events are generated each
time a match between the internal counter and one of
the Period registers occurs.

15.2
Compare Operations
In Compare mode (Figure 15-1), the output compare
module can be configured for single-shot or continuous
pulse generation. It can also repeatedly toggle an
output pin on each timer event.
To set up the module for compare operations:
1.
2.
Configure the OCx output for one of the
available Peripheral Pin Select pins.
Calculate the required values for the OCxR and
(for Double Compare modes) OCxRS Duty
Cycle registers:
a) Determine the instruction clock cycle time.
Take into account the frequency of the
external clock to the timer source (if one is
used) and the timer prescaler settings.
b) Calculate time to the rising edge of the
output pulse relative to the timer start value
(0000h).
c) Calculate the time to the falling edge of the
pulse based on the desired pulse width and
the time to the rising edge of the pulse.
DS30009312C-page 230
3.
4.
5.
6.
7.
8.
Write the rising edge value to OCxR and the
falling edge value to OCxRS.
Set the Timer Period register, PRy, to a value
equal to or greater than the value in OCxRS.
Set the OCM<2:0> bits for the appropriate
compare operation (= 0xx).
For Trigger mode operations, set OCTRIG to
enable Trigger mode. Set or clear TRIGMODE
to configure trigger operation and TRIGSTAT to
select a hardware or software trigger. For
Synchronous mode, clear OCTRIG.
Set the SYNCSEL<4:0> bits to configure the
trigger or synchronization source. If free-running
timer operation is required, set the SYNCSELx
bits to �00000’ (no sync/trigger source).
Select the time base source with the
OCTSEL<2:0> bits. If necessary, set the TON bit
for the selected timer, which enables the compare time base to count. Synchronous mode
operation starts as soon as the time base is
enabled; Trigger mode operation starts after a
trigger source event occurs.
пѓЈ 2012-2014 Microchip Technology Inc.
PIC24FJ128GC010 FAMILY
For 32-bit cascaded operation, these steps are also
necessary:
1.
2.
3.
4.
5.
6.
Set the OC32 bits for both registers
(OCyCON2<8>) and (OCxCON2<8>). Enable
the even numbered module first to ensure the
modules will start functioning in unison.
Clear the OCTRIG bit of the even module
(OCyCON2<7>), so the module will run in
Synchronous mode.
Configure the desired output and Fault settings
for OCy.
Force the output pin for OCx to the output state
by clearing the OCTRIS bit.
If Trigger mode operation is required, configure
the trigger options in OCx by using the OCTRIG
(OCxCON2<7>), TRIGMODE (OCxCON1<3>)
and SYNCSELx (OCxCON2<4:0>) bits.
Configure the desired Compare or PWM mode
of operation (OCM<2:0>) for OCy first, then for
OCx.
15.3
In PWM mode, the output compare module can be
configured for edge-aligned or center-aligned pulse
waveform generation. All PWM operations are
double-buffered (buffer registers are internal to the
module and are not mapped into SFR space).
To configure the output compare module for PWM
operation:
1.
2.
3.
4.
Depending on the output mode selected, the module
holds the OCx pin in its default state and forces a transition to the opposite state when OCxR matches the
timer. In Double Compare modes, OCx is forced back
to its default state when a match with OCxRS occurs.
The OCxIF interrupt flag is set after an OCxR match in
Single Compare modes and after each OCxRS match
in Double Compare modes.
5.
Single-shot pulse events only occur once, but may be
repeated by simply rewriting the value of the
OCxCON1 register. Continuous pulse events continue
indefinitely until terminated.
8.
6.
7.
9.
Configure the OCx output for one of the
available Peripheral Pin Select pins.
Calculate the desired duty cycles and load them
into the OCxR register.
Calculate the desired period and load it into the
OCxRS register.
Select the current OCx as the synchronization
source by writing 0x1F to the SYNCSEL<4:0>
bits (OCxCON2<4:0>) and �0’ to the OCTRIG bit
(OCxCON2<7>).
Select a clock source by writing to the
OCTSEL<2:0> bits (OCxCON1<12:10>).
Enable interrupts, if required, for the timer and
output compare modules. The output compare
interrupt is required for PWM Fault pin
utilization.
Select the desired PWM mode in the OCM<2:0>
bits (OCxCON1<2:0>).
Appropriate Fault inputs may be enabled by
using the ENFLT<2:0> bits, as described in
Register 15-1.
If a timer is selected as a clock source, set the
selected timer prescale value. The selected
timer’s prescaler output is used as the clock
input for the OCx timer and not the selected
timer output.

15.3.1
PWM PERIOD
The PWM period is specified by writing to PRy, the
Timer Period register. The PWM period can be
calculated using Equation 15-1.
CALCULATING THE PWM PERIOD(1)
EQUATION 15-1:
PWM Period = [(PRy) + 1 • TCY • (Timer Prescale Value)
Where:
PWM Frequency = 1/[PWM Period]
Note 1:
Note:
Based on TCY = TOSC * 2; Doze mode and PLL are disabled.
A PRy value of N will produce a PWM period of N + 1 time base count cycles. For example, a value of 7,
written into the PRy register, will yield a period consisting of 8 time base cycles.

15.3.2
PWM DUTY CYCLE
Some important boundary parameters of the PWM duty
cycle include:
The PWM duty cycle is specified by writing to the
OCxRS and OCxR registers. The OCxRS and OCxR
registers can be written to at any time, but the duty
cycle value is not latched until a match between PRy
and TMRy occurs (i.e., the period is complete). This
provides a double buffer for the PWM duty cycle and is
essential for glitchless PWM operation.

Table 15-1 and Table 15-2 show example PWM
frequencies and resolutions for a device operating at
4 MIPS and 10 MIPS, respectively.
CALCULATION FOR MAXIMUM PWM RESOLUTION(1)
EQUATION 15-2:
Note 1:
• If OCxR, OCxRS and PRy are all loaded with
0000h, the OCx pin will remain low (0% duty cycle).
• If OCxRS is greater than PRy, the pin will remain
high (100% duty cycle).
PWM PERIOD AND DUTY CYCLE CALCULATIONS(1)
Find the Timer Period register value for a desired PWM frequency of 52.08 kHz, where FOSC = 8 MHz with
PLL (32 MHz device clock rate) and a Timer2 prescaler setting of 1:1.
TCY = 2 * TOSC = 62.5 ns
PWM Period = 1/PWM Frequency = 1/52.08 kHz = 19.2 ms
PWM Period = (PR2 + 1) • TCY • (Timer2 Prescale Value)
19.2 ms = (PR2 + 1) • 62.5 ns • 1
PR2 = 306
2.
Find the maximum resolution of the duty cycle that can be used with a 52.08 kHz frequency and a 32 MHz
device clock rate:
PWM Resolution = log10 (FCY/FPWM)/log102) bits
= (log10 (16 MHz/52.08 kHz)/log102) bits
= 8.3 bits

SERIAL PERIPHERAL
INTERFACE (SPI)
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Serial Peripheral Interface (SPI)”
(DS70005185). The information in this
data sheet supersedes the information in
the FRM.
The Serial Peripheral Interface (SPI) module is a
synchronous serial interface useful for communicating
with other peripheral or microcontroller devices. These
peripheral devices may be serial EEPROMs, shift
registers, display drivers, A/D Converters, etc. The SPI
module is compatible with the MotorolaВ® SPI and SIOP
interfaces. All devices of the PIC24FJ128GC010 family
include two SPI modules.
The modules support operation in two buffer modes. In
Standard Buffer mode, data is shifted through a single
serial buffer. In Enhanced Buffer mode, data is shifted
through an 8-level FIFO buffer.
Note:
The module also supports a basic framed SPI protocol
while operating in either Master or Slave mode. A total
of four framed SPI configurations are supported.
The SPI serial interface consists of four pins:
•
•
•
•
SDIx: Serial Data Input
SDOx: Serial Data Output
SCKx: Shift Clock Input or Output
SSx: Active-Low Slave Select or Frame
Synchronization I/O Pulse
The SPIx module can be configured to operate using 2,
3 or 4 pins. In the 3-pin mode, SSx is not used; in the
2-pin mode, both SDOx and SSx are not used.
Block diagrams of the module in Standard and
Enhanced modes are shown in Figure 16-1 and
Figure 16-2.
Note:
In this section, the SPI modules are
referred to together as SPIx, or separately
as SPI1 or SPI2. Special Function Registers will follow a similar notation. For
example, SPIxCON1 and SPIxCON2
refer to the control registers for any of the
two SPI modules.
Do not perform Read/Modify/Write operations (such as bit-oriented instructions) on
the SPIxBUF register in either Standard or
Enhanced Buffer mode.

Setting Baud Rate When
Operating as a Bus Master
17.3
The I2CxMSK register (Register 17-3) designates
address bit positions as “don’t care” for both 7-Bit and
10-Bit Addressing modes. Setting a particular bit location (= 1) in the I2CxMSK register causes the slave
module to respond, whether the corresponding
address bit value is a �0’ or a �1’. For example, when
I2CxMSK is set to �00100000’, the slave module will
detect both addresses, �0000000’ and �0100000’.
To compute the Baud Rate Generator reload value, use

The maximum baud rate (BRGH = 1) possible is FCY/4

is FCY/(4 * 65536).
Writing a new value to the UxBRG register causes the
BRG timer to be reset (cleared). This ensures the BRG
does not wait for a timer overflow before generating the
new baud rate.

Set up the UARTx:
a) Write appropriate values for data, parity and
Stop bits.
b) Write appropriate baud rate value to the
UxBRG register.
c) Set up transmit and receive interrupt enable
and priority bits.
Enable the UARTx.
Set the UTXEN bit (causes a transmit interrupt,
two cycles after being set).
Write a data byte to the lower byte of the
UxTXREG word. The value will be immediately
transferred to the Transmit Shift Register (TSR)
and the serial bit stream will start shifting out
with the next rising edge of the baud clock.
Alternatively, the data byte may be transferred
while UTXEN = 0 and then the user may set
UTXEN. This will cause the serial bit stream to
begin immediately because the baud clock will
start from a cleared state.
A transmit interrupt will be generated as per
interrupt control bit, UTXISELx.

A word write to UxTXREG triggers the transfer

A receive interrupt will be generated when one
or more data characters have been received, as

Read the OERR bit to determine if an overrun
error has occurred. The OERR bit must be reset
in software.
Read UxRXREG.
The act of reading the UxRXREG character will move
the next character to the top of the receive FIFO,
including a new set of PERR and FERR values.
18.6
Operation of UxCTS and UxRTS
Control Pins
UARTx Clear-to-Send (UxCTS) and Request-to-Send
(UxRTS) are the two hardware controlled pins that are
associated with the UARTx module. These two pins
allow the UARTx to operate in Simplex and Flow
Control mode. They are implemented to control the
transmission and reception between the Data Terminal
Equipment (DTE). The UEN<1:0> bits in the UxMODE
register configure these pins.
18.7
Infrared Support
The UARTx module provides two types of infrared
UART support: one is the IrDA clock output to support
an external IrDA encoder and decoder device (legacy
module support), and the other is the full implementation of the IrDA encoder and decoder. Note that
because the IrDA modes require a 16x baud clock, they
will only work when the BRGH bit (UxMODE<3>) is �0’.
18.7.1
IrDA CLOCK OUTPUT FOR
EXTERNAL IrDA SUPPORT
To support external IrDA encoder and decoder devices,
the BCLKx pin (same as the UxRTS pin) can be
configured to generate the 16x baud clock. With
UEN<1:0> = 11, the BCLKx pin will output the
16x baud clock if the UARTx module is enabled. It can
be used to support the IrDA codec chip.
18.7.2
BUILT-IN IrDA ENCODER AND
DECODER
The UARTx has full implementation of the IrDA
encoder and decoder as part of the UARTx module.
The built-in IrDA encoder and decoder functionality is
enabled using the IREN bit (UxMODE<12>). When
enabled (IREN = 1), the receive pin (UxRX) acts as the
input from the infrared receiver. The transmit pin
(UxTX) acts as the output to the infrared transmitter.

UNIVERSAL SERIAL BUS WITH
ON-THE-GO SUPPORT (USB
OTG)
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “USB On-The-Go (OTG)”
(DS39721). The information in this data
sheet supersedes the information in the
FRM.
PIC24FJ128GC010 family devices contain a full-speed
and low-speed compatible, On-The-Go (OTG) USB
Serial Interface Engine (SIE). The OTG capability
allows the device to act as either a USB peripheral
device or as a USB embedded host with limited host
capabilities. The OTG capability allows the device to
dynamically switch from device to host operation using
OTG’s Host Negotiation Protocol (HNP).
A simplified block diagram of the USB OTG module is
shown in Figure 19-1.
The USB OTG module can function as a USB peripheral
device or as a USB host, and may dynamically switch
between Device and Host modes under software
control. In either mode, the same data paths and Buffer
Descriptors (BDs) are used for the transmission and
reception of data.
In discussing USB operation, this section will use a
controller-centric nomenclature for describing the direction of the data transfer between the microcontroller and
the USB. RX (Receive) will be used to describe transfers
that move data from the USB to the microcontroller and
TX (Transmit) will be used to describe transfers that
move data from the microcontroller to the USB.
Table 19-1 shows the relationship between data
direction in this nomenclature and the USB tokens
exchanged.
TABLE 19-1:
For more details on OTG operation, refer to the
“On-The-Go Supplement” to the “USB 2.0 Specification”, published by the USB-IF. For more details on
USB operation, refer to the “Universal Serial Bus
Specification”, v2.0.

This chapter presents the most basic operations
needed to implement USB OTG functionality in an
application. A complete and detailed discussion of the
USB protocol and its OTG supplement are beyond the
scope of this data sheet. It is assumed that the user
already has a basic understanding of USB architecture
and the latest version of the protocol.
Not all steps for proper USB operation (such as device
enumeration) are presented here. It is recommended
that application developers use an appropriate device
driver to implement all of the necessary features.
Microchip provides a number of application-specific
resources, such as USB firmware and driver support.

19.1
Hardware Configuration
19.1.1
19.1.1.1
DEVICE MODE
D+ Pull-up Resistor
PIC24FJ128GC010 family devices have a built-in
1.5 kпЃ— resistor on the D+ line that is available when the
microcontroller is operating in Device mode. This is
used to signal an external host that the device is
operating in Full-Speed Device mode. It is engaged by
setting the USBEN bit (U1CON<0>) and powering up
the USB module (USBPWR = 1). If the OTGEN bit
(U1OTGCON<2>) is set, then the D+ pull-up is enabled
through the DPPULUP bit (U1OTGCON<7>).
19.1.1.2
The VBUS Pin
In order to meet the USB 2.0 specification requirement,
relating to the back drive voltage on the D+/D- pins, the
USB module incorporates VBUS-level sensing comparators. When the comparators detect the VBUS level
below the VA_SESS_VLD level, the hardware will automatically disable the D+ pull-up resistor described in
Section 19.1.1.1 “D+ Pull-up Resistor”. This allows
the device to automatically meet the back drive
requirement for D+ and D-, even if the application
firmware does not explicitly monitor the VBUS level.
Therefore, the VBUS microcontroller pin should not be
left floating in USB Device mode application designs
and should normally be connected to the VBUS pin on
the USB connector/cable (either directly or through a
small resistance п‚Ј 100 ohms).
19.1.1.3
To meet compliance specifications, the USB module
(and the D+ or D- pull-up resistor) should not be enabled
until the host actively drives VBUS high. One of the 5.5V
tolerant I/O pins may be used for this purpose.
The application should never source any current onto
the 5V VBUS pin of the USB cable when the USB
module is operated in USB Device mode.
The Dual Power mode with Self-Power Dominance
(Figure 19-4) allows the application to use internal
power primarily, but switch to power from the USB
when no internal power is available. Dual power
devices must also meet all of the special requirements
for inrush current and Suspend mode current previously described, and must not enable the USB module
until VBUS is driven high.

Bus Power Only mode (Figure 19-2) is effectively the
simplest method. All power for the application is drawn
from the USB.
To meet the inrush current requirements of the
“USB 2.0 OTG Specification”, the total effective capacitance, appearing across VBUS and ground, must be no
more than 10 пЃ­F.
In the USB Suspend mode, devices must consume no
more than 2.5 mA from the 5V VBUS line of the USB
cable. During the USB Suspend mode, the D+ or Dpull-up resistor must remain active, which will consume
some of the allowed suspend current.

In Self-Power Only mode (Figure 19-3), the USB

power being pulled from the USB. Note that an attach
indication is added to indicate when the USB has been
connected and the host is actively powering VBUS.

HOST AND OTG MODES
19.1.2.1
19.1.2.2
In Host mode, as well as Host mode in On-The-Go
operation, the “USB 2.0 OTG Specification” requires
that the host application should supply power on VBUS.
Since the microcontroller is running below VBUS, and is
not able to source sufficient current, a separate power
supply must be provided.
D+ and D- Pull-Down Resistors
PIC24FJ128GC010 family devices have a built-in
15 kпЃ— pull-down resistor on the D+ and D- lines. These
are used in tandem to signal to the bus that the microcontroller is operating in Host mode. They are engaged
by setting the HOSTEN bit (U1CON<3>). If the OTGEN
bit (U1OTGCON<2>) is set, then these pull-downs are
enabled by setting the DPPULDWN and DMPULDWN
bits (U1OTGCON<5:4>).
FIGURE 19-5:
Power Configurations
When the application is always operating in Host mode,
a simple circuit can be used to supply VBUS and
regulate current on the bus (Figure 19-5). For OTG
operation, it is necessary to be able to turn VBUS on or
off as needed, as the microcontroller switches between
Device and Host modes. A typical example using an
external charge pump is shown in Figure 19-6.

USING AN EXTERNAL INTERFACE
Some applications may require the USB interface to
be isolated from the rest of the system.
PIC24FJ128GC010 family devices include a complete
interface to communicate with and control an external
USB transceiver, including the control of data line
pull-ups and pull-downs. The VBUS voltage generation
control circuit can also be configured for different VBUS
generation topologies.
Refer to the “dsPIC33/PIC24 Family Reference
Manual”, “USB On-The-Go (OTG)” for information on
using the external interface.
19.1.4
CALCULATING TRANSCEIVER
POWER REQUIREMENTS
The USB transceiver consumes a variable amount of
current depending on the characteristic impedance of
the USB cable, the length of the cable, the VUSB supply
voltage and the actual data patterns moving across the
USB cable. Longer cables have larger capacitances
and consume more total energy when switching output
states. The total transceiver current consumption will
be application-specific. Equation 19-1 can help
estimate how much current actually may be required in
full-speed applications.
Refer to the “dsPIC33/PIC24 Family Reference
Manual”, “USB On-The-Go (OTG)” for a complete
discussion on transceiver power consumption.

USB Buffer Descriptors and the
BDT
Endpoint buffer control is handled through a structure
called the Buffer Descriptor Table (BDT). This provides
a flexible method for users to construct and control
endpoint buffers of various lengths and configurations.
The BDT can be located in any available 512-byte,
aligned block of data RAM. The BDT Pointer
(U1BDTP1) contains the upper address byte of the
BDT and sets the location of the BDT in RAM. The user
must set this pointer to indicate the table’s location.
The BDT is composed of Buffer Descriptors (BDs)
which are used to define and control the actual buffers
in the USB RAM space. Each BD consists of two 16-bit,
“soft” (non-fixed-address) registers, BDnSTAT and
BDnADR, where n represents one of the 64 possible
BDs (range of 0 to 63). BDnSTAT is the status register
for BDn, while BDnADR specifies the starting address
for the buffer associated with BDn.
Note:
Since BDnADR is a 16-bit register, only
the first 64 Kbytes of RAM can be
accessed by the USB module.
FIGURE 19-7:
Depending on the endpoint buffering configuration
used, there are up to 64 sets of Buffer Descriptors, for
a total of 256 bytes. At a minimum, the BDT must be at
least 8 bytes long. This is because the “USB 2.0 OTG
Specification” mandates that every device must have
Endpoint 0 with both input and output for initial setup.
Endpoint mapping in the BDT is dependent on three
variables:
• Endpoint number (0 to 15)
• Endpoint direction (RX or TX)
• Ping-pong settings (U1CNFG1<1:0>)
Figure 19-7 illustrates how these variables are used to
map endpoints in the BDT.
In Host mode, only Endpoint 0 Buffer Descriptors are
used. All transfers utilize the Endpoint 0 Buffer Descriptor and USB Endpoint 0 Control register (U1EP0). For
received packets, the attached device’s source endpoint
is indicated by the value of ENDPT<3:0> in the USB
Status register (U1STAT<7:4>). For transmitted packets,
the attached device’s destination endpoint is indicated
by the value written to the USB Token register (U1TOK).

BDs have a fixed relationship to a particular endpoint,
depending on the buffering configuration. Table 19-2
provides the mapping of BDs to endpoints. This relationship also means that gaps may occur in the BDT if
endpoints are not enabled contiguously. This, theoretically, means that the BDs for disabled endpoints could
be used as buffer space. In practice, users should
avoid using such spaces in the BDT unless a method
of validating BD addresses is implemented.
19.2.1
corresponding data buffer during this time. Note that
the microcontroller core can still read BDnSTAT while
the SIE owns the buffer and vice versa.
The Buffer Descriptors have a different meaning based
on the source of the register update. Register 19-1 and
Register 19-2 show the differences in BDnSTAT
depending on its current “ownership”.
When UOWN is set, the user can no longer depend on
the values that were written to the BDs. From this point,
the USB module updates the BDs as necessary, overwriting the original BD values. The BDnSTAT register is
updated by the SIE with the token PID and the transfer
count is updated.
BUFFER OWNERSHIP
Because the buffers and their BDs are shared between
the CPU and the USB module, a simple semaphore
mechanism is used to distinguish which is allowed to
update the BD and associated buffers in memory. This
is done by using the UOWN bit as a semaphore to
distinguish which is allowed to update the BD and
associated buffers in memory. UOWN is the only bit
that is shared between the two configurations of
BDnSTAT.
19.2.2
The USB OTG module uses a dedicated DMA to
access both the BDT and the endpoint data buffers.
Since part of the address space of the DMA is dedicated to the Buffer Descriptors, a portion of the memory
connected to the DMA must comprise a contiguous
address space, properly mapped for the access by the
module.
When UOWN is clear, the BD entry is “owned” by the
microcontroller core. When the UOWN bit is set, the BD
entry and the buffer memory are “owned” by the USB
peripheral. The core should not modify the BD or its

An interrupt condition in any of these triggers a USB
Error Interrupt Flag (UERRIF) in the top level. Unlike
the device-level interrupt flags in the IFSx registers,
USB interrupt flags in the U1IR registers can only be
cleared by writing a �1’ to the bit position.
USB Interrupts
The USB OTG module has many conditions that can
be configured to cause an interrupt. All interrupt
sources use the same interrupt vector.
Figure 19-8 shows the interrupt logic for the USB
module. There are two layers of interrupt registers in
the USB module. The top level consists of overall USB
status interrupts; these are enabled and flagged in the
U1IE and U1IR registers, respectively. The second
level consists of USB error conditions, which are
enabled and flagged in the U1EIR and U1EIE registers.
FIGURE 19-8:
Interrupts may be used to trap routine events in a USB
transaction. Figure 19-9 provides some common
events within a USB frame and their corresponding
interrupts.

CLEARING USB OTG INTERRUPTS
Note:
Unlike device-level interrupts, the USB OTG interrupt
status flags are not freely writable in software. All USB
OTG flag bits are implemented as hardware settable
only bits. Additionally, these bits can only be cleared in
software by writing a �1’ to their locations (i.e., performing a MOV type instruction). Writing a �0’ to a flag bit (i.e.,
a BCLR instruction) has no effect.
FIGURE 19-9:
Throughout this data sheet, a bit that can
only be cleared by writing a �1’ to its location is referred to as “Write 1 to clear”. In
register descriptions, this function is
indicated by the descriptor, “K”.

ENABLE HOST MODE AND
DISCOVER A CONNECTED DEVICE
1.
Enable Host mode by setting the HOSTEN bit
(U1CON<3>). This causes the Host mode control bits in other USB OTG registers to become
available.
2. Enable the D+ and D- pull-down resistors by
setting the DPPULDWN and DMPULDWN bits

DMPULUP bits (U1OTGCON<7:6>).
3. At this point, SOF generation begins with the
SOF counter loaded with 12,000. Eliminate
noise on the USB by clearing the SOFEN bit
(U1CON<0>) to disable Start-of-Frame (SOF)
packet generation.
4. Enable the device attached interrupt by setting
the ATTACHIE bit (U1IE<6>).
5. Wait for the device attached interrupt
(U1IR<6> = 1). This is signaled by the USB
device changing the state of D+ or D- from �0’
to �1’ (SE0 to J-state). After it occurs, wait
100 ms for the device power to stabilize.
6. Check the state of the JSTATE and SE0 bits in
U1CON. If the JSTATE bit (U1CON<7>) is �0’,
the connecting device is low speed. If the connecting device is low speed, set the LSPDEN
and LSPD bits (U1ADDR<7> and U1EP0<7>) to
enable low-speed operation.
7. Reset the USB device by setting the USBRST
bit (U1CON<4>) for at least 50 ms, sending
Reset signaling on the bus. After 50 ms,
terminate the Reset by clearing USBRST.
8. In order to keep the connected device from
going into suspend, enable the SOF packet
generation by setting the SOFEN bit.
9. Wait 10 ms for the device to recover from Reset.
10. Perform enumeration as described by Chapter 9

COMPLETE A CONTROL
TRANSACTION TO A CONNECTED
DEVICE
Follow the procedure described in Section 19.5.1
“Enable Host Mode and Discover a Connected
Device” to discover a device.
Set up the Endpoint Control 0 register for
bidirectional control transfers by writing 0Dh to
U1EP0 (this sets the EPCONDIS, EPTXEN and
EPHSHK bits).
Place a copy of the device framework setup
command in a memory buffer. See Chapter 9 of
the “USB 2.0 Specification” for information on
the device framework command set.
Initialize the Buffer Descriptor (BD) for the
current (even or odd) TX EP0 to transfer the
eight bytes of command data for a device
framework command (i.e., GET
DEVICE
DESCRIPTOR):
a) Set the BD Data Buffer Address (BD0ADR)
to the starting address of the 8-byte
memory buffer containing the command.
b) Write 8008h to BD0STAT (this sets the
UOWN bit and sets a byte count of 8).
Set the USB device address of the target device
in the address register (U1ADDR<6:0>). After a
USB bus Reset, the device USB address will be
zero. After enumeration, it will be set to another
value between 1 and 127.
Write D0h to U1TOK; this is a SETUP token to
Endpoint 0, the target device’s default control
pipe. This initiates a SETUP token on the bus,
followed by a data packet. The device handshake is returned in the PID field of BD0STAT
after the packets are complete. When the USB
module updates BD0STAT, a Token Complete
Interrupt Flag is asserted (the TRNIF flag is set).
This completes the setup phase of the setup
transaction, as referenced in Chapter 9 of the
“USB 2.0 Specification”.
To initiate the data phase of the setup transaction (i.e., get the data for the GET DEVICE
DESCRIPTOR command), set up a buffer in
memory to store the received data.
8.
Initialize the current (even or odd) RX or TX (RX
for IN, TX for OUT) EP0 BD to transfer the data.
a) Write C040h to BD0STAT. This sets the
UOWN, configures Data Toggle (DTS) to
DATA1 and sets the byte count to the length
of the data buffer (64 or 40h in this case).
b) Set BD0ADR to the starting address of the
data buffer.
9. Write the Token register with the appropriate IN
or OUT token to Endpoint 0, the target device’s
default control pipe (e.g., write 90h to U1TOK for
an IN token for a GET DEVICE DESCRIPTOR
command). This initiates an IN token on the bus,
followed by a data packet from the device to the
host. When the data packet completes, the
BD0STAT is written and a Token Complete Interrupt Flag is asserted (the TRNIF flag is set). For
control transfers with a single packet data
phase, this completes the data phase of the
setup transaction, as referenced in Chapter 9 of
the “USB 2.0 Specification”. If more data needs
to be transferred, return to Step 8.
10. To initiate the status phase of the setup transaction, set up a buffer in memory to receive or send
the zero length status phase data packet.
11. Initialize the current (even or odd) TX EP0 BD to
transfer the status data:
a) Set the BDT buffer address field to the start
address of the data buffer.
b) Write 8000h to BD0STAT (set UOWN bit,
configure DTS to DATA0 and set byte count
to 0).
12. Write the Token register with the appropriate IN
or OUT token to Endpoint 0, the target device’s
default control pipe (e.g., write 01h to U1TOK for
an OUT token for a GET DEVICE DESCRIPTOR
command). This initiates an OUT token on the
bus, followed by a zero length data packet from
the host to the device. When the data packet
completes, the BD is updated with the handshake from the device and a Token Complete
Interrupt Flag is asserted (the TRNIF flag is set).
This completes the status phase of the setup
transaction, as described in Chapter 9 of the
“USB 2.0 Specification”.

SEND A FULL-SPEED BULK DATA
TRANSFER TO A TARGET DEVICE
Follow the procedure described in Section 19.5.1
“Enable Host Mode and Discover a Connected
Device” and Section 19.5.2 “Complete a Control Transaction to a Connected Device” to
discover and configure a device.
To enable transmit and receive transfers with
handshaking enabled, write 1Dh to U1EP0. If
the target device is a low-speed device, also set
the LSPD (U1EP0<7>) bit. If you want the hardware to automatically retry indefinitely if the
target device asserts a NAK on the transfer;
clear the Retry Disable bit, RETRYDIS
(U1EP0<6>).
Set up the BD for the current (even or odd) TX
EP0 to transfer up to 64 bytes.
Set the USB device address of the target device
in the USB Address register (U1ADDR<6:0>).
Write an OUT token to the desired endpoint to
U1TOK. This triggers the module’s transmit
state machines to begin transmitting the token
and the data.
Wait for the Token Complete Interrupt Flag,
TRNIF. This indicates that the BD has been
released back to the microprocessor and the
transfer has completed. If the Retry Disable bit
(RETRYDIS) is set, the handshake (ACK, NAK,
STALL or ERROR (0Fh)) is returned in the BD
PID field. If a STALL interrupt occurs, the
pending packet must be dequeued and the error
condition in the target device cleared. If a detach
interrupt occurs (SE0 for more than 2.5 Вµs), then
the target has detached (U1IR<0> is set).
Once the Token Complete Interrupt Flag occurs
(TRNIF is set), the BD can be examined and the
next data packet queued by returning to Step 2.
Note:
USB speed, transceiver and pull-ups
should only be configured during the
module setup phase. It is not recommended to change these settings while
the module is enabled.

19.6.1
OTG Operation
SESSION REQUEST PROTOCOL
(SRP)
An OTG A-device may decide to power down the VBUS
supply when it is not using the USB link through the
Session Request Protocol (SRP). Software may do this
by configuring a GPIO pin to disable an external power
transistor, or voltage regulator enable signal, which controls the VBUS supply. When the VBUS supply is powered
down, the A-device is said to have ended a USB session.
An OTG A-device or embedded host may repower the
VBUS supply at any time (initiate a new session). An
OTG B-device may also request that the OTG A-device
repower the VBUS supply (initiate a new session). This
is accomplished via Session Request Protocol (SRP).
Prior to requesting a new session, the B-device must first
check that the previous session has definitely ended. To
do this, the B-device must check for two conditions:
1.
2.
VBUS supply is below the session valid voltage.
Both D+ and D- have been low for at least 2 ms.
The B-device will be notified of Condition 1 by the
SESENDIF (U1OTGIR<2>) interrupt. Software will
have to manually check for Condition 2.
Note:
When the A-device powers down the
VBUS supply, the B-device must disconnect its pull-up resistor from power. If the
device is self-powered, it can do this by
clearing DPPULUP (U1OTGCON<7>) and
DMPULUP (U1OTGCON<6>).
The B-device may aid in achieving Condition 1 by discharging the VBUS supply through a resistor. Software
may do this by setting VBUSDIS (U1OTGCON<0>).
After these initial conditions are met, the B-device may
begin requesting the new session. The B-device begins
by pulsing the D+ data line. Software should do this by
setting DPPULUP (U1OTGCON<7>). The data line
should be held high for 5 to 10 ms.
The B-device then proceeds by pulsing the VBUS
supply. Software should do this by setting PUVBUS
(U1CNFG2<4>). When an A-device detects SRP signaling (either via the ATTACHIF (U1IR<6>) interrupt or
via the SESVDIF (U1OTGIR<3>) interrupt), the
A-device must restore the VBUS supply by properly
configuring the general purpose I/O port pin controlling
the external power source.
The B-device should not monitor the state of the VBUS
supply while performing VBUS supply pulsing. When the
B-device does detect that the VBUS supply has been
restored (via the SESVDIF (U1OTGIR<3>) interrupt),
the B-device must reconnect to the USB link by pulling
up D+ or D- (via the DPPULUP or DMPULUP bit).
The A-device must complete the SRP by driving USB
Reset signaling.

19.6.2
HOST NEGOTIATION PROTOCOL
(HNP)
In USB OTG applications, a Dual Role Device (DRD) is
a device that is capable of being either a host or a
peripheral. Any OTG DRD must support Host
Negotiation Protocol (HNP).
HNP allows an OTG B-device to temporarily become
the USB host. The A-device must first enable the
B-device to follow HNP. Refer to the “On-The-Go
Supplement” to the “USB 2.0 Specification” for more
information regarding HNP. HNP may only be initiated
at full speed.
After being enabled for HNP by the A-device, the
B-device requests being the host any time that the USB
link is in suspend state, by simply indicating a disconnect. This can be done in software by clearing
DPPULUP and DMPULUP. When the A-device detects
the disconnect condition (via the URSTIF (U1IR<0>)
interrupt), the A-device may allow the B-device to take
over as host. The A-device does this by signaling connect as a full-speed function. Software may accomplish
this by setting DPPULUP.
When the B-device has finished in its role as host, it
stops all bus activity and turns on its D+ pull-up resistor
by setting DPPULUP. When the A-device detects a
suspend condition (Idle for 3 ms), the A-device turns off
its D+ pull-up. The A-device may also power down the
VBUS supply to end the session. When the A-device
detects the connect condition (via ATTACHIF), the
A-device resumes host operation and drives Reset
signaling.
19.6.3
EXTERNAL VBUS COMPARATORS
The external VBUS comparator option is enabled by setting the UVCMPDIS bit (U1CNFG2<1>). This disables
the internal VBUS comparators, removing the need to
attach VBUS to the microcontroller’s VBUS pin.
The external comparator interface uses either the
VCMPST1 and VCMPST2 pins, or the VBUSVLD,
SESSVLD and SESSEND pins, based upon the setting
of the UVCMPSEL bit (U1CNFG2<5>). These pins are
digital inputs and should be set in the following patterns
(see Table 19-3), based on the current level of the VBUS
voltage.
If the A-device responds instead with resume signaling,
the A-device remains as host. When the B-device
detects the connect condition (via ATTACHIF
(U1IR<6>), the B-device becomes host. The B-device
drives Reset signaling prior to using the bus.

USB OTG Module Registers
There are a total of 37 memory-mapped registers associated with the USB OTG module. They can be divided
into four general categories:
•
•
•
•
USB OTG Module Control (12)
USB Interrupt (7)
USB Endpoint Management (16)
USB VBUS Power Control (2)
This total does not include the (up to) 128 BD registers
in the BDT. Their prototypes, described in Register 19-1
and Register 19-2, are shown separately in
Section 19.2 “USB Buffer Descriptors and the BDT”.
DS30009312C-page 282
All USB OTG registers are implemented in the Least
Significant Byte (LSB) of the register. Bits in the upper
byte are unimplemented and have no function. Note
that some registers are instantiated only in Host mode,
while other registers have different bit instantiations
and functions in Device and Host modes.
The registers described in the following sections are
those that have bits with specific control and configuration features. The following registers are used for data
or address values only:
• U1BDTP1: Specifies the 256-word page in data
RAM used for the BDT; 8-bit value with bit 0 fixed
as �0’ for boundary alignment.
• U1FRML and U1FRMH: Contain the 11-bit byte
counter for the current data frame.

modulator signals and then it is provided to the MDOUT
pin. Using this method, the DSM can generate the
following types of key modulation schemes:

• Frequency Shift Keying (FSK)
• Phase-Shift Keying (PSK)
• On-Off Keying (OOK)
Figure 20-1 shows a simplified block diagram of the
Data Signal Modulator peripheral.
The Data Signal Modulator (DSM) allows the user to
mix a digital data stream (the “modulator signal”) with a
carrier signal to produce a modulated output. Both the
carrier and the modulator signals are supplied to the
DSM module, either internally from the output of a
peripheral, or externally through an input pin.

ENHANCED PARALLEL
MASTER PORT (EPMP)
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Enhanced Parallel Master Port
(EPMP)” (DS39730). The information in
this data sheet supersedes the information
in the FRM.
The Enhanced Parallel Master Port (EPMP) module provides a parallel, 4-bit (Master mode only), 8-bit (Master
and Slave modes) or 16-bit (Master mode only) data bus
interface to communicate with off-chip modules, such as
memories, FIFOs, LCD controllers and other microcontrollers. This module can serve as either the master or
the slave on the communication bus.
21.1
While all PIC24FJ128GC010 family devices implement
the EPMP, I/O pin constraints place some limits on
16-Bit Master mode operations in some package types.
This is reflected in the number of dedicated Chip Select
pins implemented and the number of dedicated
address lines that are available. The differences are
summarized in Table 21-1. All available EPMP pin
functions are summarized in Table 21-2.
For EPMP Master modes, all external addresses are
mapped into the internal Extended Data Space (EDS).
This is done by allocating a region of the EDS for each
Chip Select (CS) and then assigning each Chip Select
to a particular external resource, such as a memory or
external controller. This region should not be assigned
to another device resource, such as RAM or SFRs. To
perform a write or read on an external resource, the
CPU simply performs a write or read within the address
range assigned for the EPMP.
For 64-pin devices, the dedicated Chip Select pins
(PMCS1 and PMCS2) are not implemented. In addition, only 16 address lines (PMA<15:0>) are available.
If required, PMA14 and PMA15 can be remapped to
function as PMCS1 and PMCS2, respectively.
The memory space addressable by the device
depends on the number of address lines available, as
well as the number of Chip Select signals required for
the application. Devices with lower pin counts are more
affected by Chip Select requirements, as these take
away address lines. Table 21-1 shows the maximum
addressable range for each pin count.
Key features of the EPMP module are:
• Extended Data Space (EDS) Interface Allows
Direct Access from the CPU
• Up to 23 Programmable Address Lines
• Up to 2 Chip Select Lines
• Up to 2 Acknowledgment Lines
(one per Chip Select)
• 4-Bit, 8-Bit or 16-Bit Wide Data Bus

REAL-TIME CLOCK AND
CALENDAR (RTCC)
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the
Real-Time Clock and Calendar, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “RTCC with External Power
Control” (DS39745).
The RTCC provides the user with a Real-Time Clock
and Calendar (RTCC) function that can be calibrated.
Key features of the RTCC module are:
• Operates in Deep Sleep mode
• Selectable clock source
• Provides hours, minutes and seconds using
24-hour format
• Visibility of one half second period
• Provides calendar – weekday, date, month and year
• Alarm-configurable for half a second, one second,
ten seconds, one minute, ten minutes, one hour,
one day, one week, one month or one year
• Alarm repeat with decrementing counter
• Alarm with indefinite repeat chime
• Year 2000 to 2099 leap year correction

RTCC Source Clock
The user can select between the SOSC crystal
oscillator, LPRC internal oscillator or an external
50 Hz/60 Hz power line input as the clock reference for
the RTCC module. This gives the user an option to trade
off system cost, accuracy and power consumption,
based on the overall system needs.

TABLE 23-2:
RTCC Module Registers
The RTCC module registers are organized into three
categories:
• RTCC Control Registers
• RTCC Value Registers
• Alarm Value Registers
23.2.1
00
REGISTER MAPPING
To limit the register interface, the RTCC Timer and
Alarm Time registers are accessed through corresponding register pointers. The RTCC Value register
window (RTCVALH and RTCVALL) uses the
RTCPTR<1:0> bits (RCFGCAL<9:8>) to select the
desired Timer register pair (see Table 23-1).
By writing the RTCVALH byte, the RTCC Pointer value,
the RTCPTR<1:0> bits decrement by one until they
reach �00’. Once they reach �00’, the MINUTES and
SECONDS value will be accessible through RTCVALH
and RTCVALL until the pointer value is manually
changed.

Considering that the 16-bit core does not distinguish
between 8-bit and 16-bit read operations, the user must
be aware that when reading either the ALRMVALH or
ALRMVALL bytes, the ALRMPTR<1:0> value will be
decremented. The same applies to the RTCVALH or
RTCVALL bytes with the RTCPTR<1:0> bits being
decremented.
Note:
23.2.2
This only applies to read operations and
not write operations.
WRITE LOCK
In order to perform a write to any of the RTCC Timer
registers, the RTCWREN bit (RCFGCAL<13>) must be
set (see Example 23-1).
Note:
The Alarm Value register window (ALRMVALH and
ALRMVALL) uses the ALRMPTR<1:0> bits
(ALCFGRPT<9:8>) to select the desired Alarm
register pair (see Table 23-2).
By writing the ALRMVALH byte, the Alarm Pointer
value, ALRMPTR<1:0> bits, decrement by one until
they reach �00’. Once they reach �00’, the ALRMMIN
and ALRMSEC value will be accessible through
ALRMVALH and ALRMVALL until the pointer value is
manually changed.
ALRMVAL REGISTER
MAPPING
23.2.3
To avoid accidental writes to the timer, it is
recommended that the RTCWREN bit
(RCFGCAL<13>) is kept clear at any
other time. For the RTCWREN bit to be
set, there is only one instruction cycle time
window allowed between the 55h/AA
sequence and the setting of RTCWREN;
therefore, it is recommended that code
follow the procedure in Example 23-1.
SELECTING RTCC CLOCK SOURCE
The clock source for the RTCC module can be selected
using the RTCLK<1:0> bits in the RTCPWC register.
When the bits are set to �00’, the Secondary Oscillator
(SOSC) is used as the reference clock and when the bits
are �01’, LPRC is used as the reference clock. When
RTCLK<1:0> = 10 and 11, the external power line
(50 Hz and 60 Hz) is used as the clock source.
SETTING THE RTCWREN BIT

(“push w8”);
(“disi #5”);
(“mov #0x55, w7”);

Calibration
The real-time crystal input can be calibrated using the
periodic auto-adjust feature. When properly calibrated,
the RTCC can provide an error of less than 3 seconds
per month. This is accomplished by finding the number
of error clock pulses and storing the value into the
lower half of the RCFGCAL register. The 8-bit signed
value loaded into the lower half of RCFGCAL is
multiplied by four and will either be added or subtracted
from the RTCC timer, once every minute. Refer to the
steps below for RTCC calibration:
1.
2.
3.
Using another timer resource on the device, the
user must find the error of the 32.768 kHz crystal.
Once the error is known, it must be converted to
the number of error clock pulses per minute.
a) If the oscillator is faster than ideal (negative
result from Step 2), the RCFGCAL register value
must be negative. This causes the specified
number of clock pulses to be subtracted from
the timer counter, once every minute.
b) If the oscillator is slower than ideal (positive
result from Step 2), the RCFGCAL register value
must be positive. This causes the specified
number of clock pulses to be subtracted from
the timer counter, once every minute.
EQUATION 23-1:
(Ideal Frequency†– Measured Frequency) * 60 =
Clocks per Minute
†Ideal Frequency = 32,768 Hz
Writes to the lower half of the RCFGCAL register
should only occur when the timer is turned off, or
immediately after the rising edge of the seconds pulse,
except when SECONDS = 00, 15, 30 or 45. This is due
to the auto-adjust of the RTCC at 15 second intervals.
Note:
23.5
It is up to the user to include, in the error
value, the initial error of the crystal: drift
due to temperature and drift due to crystal
aging.
Alarm
• Configurable from half second to one year
• Enabled using the ALRMEN bit
(ALCFGRPT<15>)
• One-time alarm and repeat alarm options
available
пѓЈ 2012-2014 Microchip Technology Inc.
23.5.1
CONFIGURING THE ALARM
The alarm feature is enabled using the ALRMEN bit.
This bit is cleared when an alarm is issued. Writes to
ALRMVAL should only take place when ALRMEN = 0.
As shown in Figure 23-2, the interval selection of the
alarm is configured through the AMASK<3:0> bits
(ALCFGRPT<13:10>). These bits determine which,
and how many, digits of the alarm must match the clock
value for the alarm to occur.
The alarm can also be configured to repeat based on a
preconfigured interval. The amount of times this
occurs, once the alarm is enabled, is stored in the
ARPT<7:0> bits (ALCFGRPT<7:0>). When the value
of the ARPTx bits equals 00h, and the CHIME bit
(ALCFGRPT<14>) is cleared, the repeat function is
disabled and only a single alarm will occur. The alarm
can be repeated, up to 255 times by loading
ARPT<7:0> with FFh.
After each alarm is issued, the value of the ARPTx bits
is decremented by one. Once the value has reached
00h, the alarm will be issued one last time, after which,
the ALRMEN bit will be cleared automatically and the
alarm will turn off.
Indefinite repetition of the alarm can occur if the
CHIME bit = 1. Instead of the alarm being disabled
when the value of the ARPTx bits reaches 00h, it rolls
over to FFh and continues counting indefinitely while
CHIME is set.
23.5.2
ALARM INTERRUPT
At every alarm event, an interrupt is generated. In
addition, an alarm pulse output is provided that
operates at half the frequency of the alarm. This output
is completely synchronous to the RTCC clock and can
be used as a trigger clock to other peripherals.
Note:
Changing any of the registers, other than
the RCFGCAL and ALCFGRPT registers,
and the CHIME bit, while the alarm is
enabled (ALRMEN = 1), can result in a
false alarm event leading to a false alarm
interrupt. To avoid a false alarm event, the
timer and alarm values should only be
changed while the alarm is disabled
(ALRMEN = 0). It is recommended that
the ALCFGRPT register and CHIME bit be
changed when RTCSYNC = 0.

Power Control
23.7
RTCC VBAT Operation
The RTCC includes a power control feature that allows
the device to periodically wake-up an external device,
wait for the device to be stable before sampling
wake-up events from that device, and then shut down
the external device. This can be done completely
autonomously by the RTCC, without the need to wake
from the current lower power mode (Sleep, Deep
Sleep, etc.).
The RTCC can operate in VBAT mode when there is a
power loss on the VDD pin. The RTCC will continue to
operate if the VBAT pin is powered on (it is usually
connected to the battery).
To use this feature:
The VBAT BOR can be enabled/disabled using the
VBTBOR bit in the CW2 Configuration register
(CW2<14>). If the VBTBOR enable bit is cleared, the
VBAT BOR is always disabled and there will be no
indication of a VBAT BOR. If the VBTBOR bit is set, the
RTCC can receive a Reset and the RTCEN bit will get
cleared; it can happen anywhere between 1.95-1.4V
(typical).
1.
2.
3.
Enable the RTCC (RTCEN = 1).
Set the PWCEN bit (RTCPWC<15>).
Configure the RTCC pin to drive the PWC control
signal (RTCOE = 1 and RTCOUT<1:0> = 11).
The polarity of the PWC control signal may be chosen
using the PWCPOL bit (RTCPWC<14>). An active-low
or active-high signal may be used with the appropriate
external switch to turn on or off the power to one or
more external devices. The active-low setting may also
be used in conjunction with an open-drain setting on
the RTCC pin, in order to drive the ground pin(s) of the
external device directly (with the appropriate external
VDD pull-up device), without the need for external
switches. Finally, the CHIME bit should be set to enable
the PWC periodicity.
DS30009312C-page 338
Note:
It is recommended to connect the VBAT
pin to VDD if the VBAT mode is not used
(not connected to the battery).

User Interface
POLYNOMIAL INTERFACE
The CRC module can be programmed for CRC
polynomials of up to the 32nd order, using up to 32 bits.
Polynomial length, which reflects the highest exponent
in the equation, is selected by the PLEN<4:0> bits
(CRCCON2<4:0>).
The CRCXORL and CRCXORH registers control which
exponent terms are included in the equation. Setting a
particular bit includes that exponent term in the equation. Functionally, this includes an XOR operation on
the corresponding bit in the CRC engine. Clearing the
bit disables the XOR.
For example, consider two CRC polynomials, one a
16-bit and the other a 32-bit equation.
EQUATION 24-1:
DATA INTERFACE
The module incorporates a FIFO that works with a
variable data width. Input data width can be configured
to any value, between 1 and 32 bits, using the
DWIDTH<4:0> bits (CRCCON2<12:8>). When the
data width is greater than 15, the FIFO is 4 words deep.
When the DWIDTHx bits are between 15 and 8, the
FIFO is 8 words deep. When the DWIDTHx bits are
less than 8, the FIFO is 16 words deep.
The data for which the CRC is to be calculated must
first be written into the FIFO. Even if the data width is
less than 8, the smallest data element that can be
written into the FIFO is 1 byte. For example, if the
DWIDTHx bits are 5, then the size of the data is
DWIDTH<4:0> + 1 or 6. The data is written as a whole
byte; the two unused upper bits are ignored by the
module.
Once data is written into the MSb of the CRCDAT registers (that is, the MSb as defined by the data width),
the value of the VWORD<4:0> bits (CRCCON1<12:8>)
increments by one. For example, if the DWIDTHx bits
are 24, the VWORDx bits will increment when bit 7 of
CRCDATH is written. Therefore, CRCDATL must
always be written to before CRCDATH.

and
X32+X26 + X23 + X22 + X16 + X12 + X11 + X10 +
X8 + X7 + X5 + X4 + X2 + X + 1
The CRC engine starts shifting data when the CRCGO
bit is set and the value of the VWORDx bits is greater
than zero.
To program these polynomials into the CRC generator,
set the register bits, as shown in Table 24-1.
Each word is copied out of the FIFO into a buffer register,
which decrements the VWORDx bits. The data is then
shifted out of the buffer. The CRC engine continues shifting at a rate of two bits per instruction cycle, until the
VWORDx bits reach zero. This means that for a given
data width, it takes half that number of instructions for
each word to complete the calculation. For example, it
takes 16 cycles to calculate the CRC for a single word of
32-bit data.
Note that the appropriate positions are set to �1’ to indicate that they are used in the equation (for example,
X26 and X23). The �0’ bit required by the equation is
always XORed; thus, X0 is a don’t care. For a polynomial of length 32, it is assumed that the 32nd bit will
be used. Therefore, the X<31:1> bits do not have the
32nd bit.
When the VWORDx bits reach the maximum value for
the configured value of the DWIDTHx bits (4, 8 or 16),
the CRCFUL bit becomes set. When the VWORDx bits
reach zero, the CRCMPT bit becomes set. The FIFO is
emptied and the VWORD<4:0> bits are set to �00000’
whenever CRCEN is �0’.
At least one instruction cycle must pass after a write to
CRCWDAT before a read of the VWORDx bits is done.

24.1.3
DATA SHIFT DIRECTION
The LENDIAN bit (CRCCON1<3>) is used to control
the shift direction. By default, the CRC will shift data
through the engine, MSb first. Setting LENDIAN (= 1)
causes the CRC to shift data, LSb first. This setting
allows better integration with various communication
schemes and removes the overhead of reversing the
bit order in software. Note that this only changes the
direction the data is shifted into the engine. The result
of the CRC calculation will still be a normal CRC result,
not a reverse CRC result.

INTERRUPT OPERATION
Preload the FIFO by writing to the CRCDATL
and CRCDATH registers until the CRCFUL bit is
set or no data is left.
Clear old results by writing 00h to CRCWDATL
and CRCWDATH. The CRCWDAT registers can
also be left unchanged to resume a previously
halted calculation.
Set the CRCGO bit to start calculation.
Write remaining data into the FIFO as space
becomes available.
When the calculation completes, CRCGO is
automatically cleared. An interrupt will be
generated if CRCISEL = 1.
Read CRCWDATL and CRCWDATH for the
result of the calculation.
The module generates an interrupt that is configurable
by the user for either of two conditions.
8.
If CRCISEL is �0’, an interrupt is generated when the
VWORD<4:0> bits make a transition from a value of �1’
to �0’. If CRCISEL is �1’, an interrupt will be generated
after the CRC operation finishes and the module sets
the CRCGO bit to �0’. Manually setting CRCGO to �0’
will not generate an interrupt. Note that when an
interrupt occurs, the CRC calculation would not yet be
complete. The module will still need (PLENx + 1)/2
clock cycles after the interrupt is generated until the
CRC calculation is finished.
There are eight registers used to control programmable
CRC operation:

OVERVIEW OF ADVANCED
ANALOG FEATURES
The defining feature of PIC24FJ128GC010 family
devices is the collection of analog peripherals, designed
to extend the range of PIC24F microcontrollers into
high-performance analog and mixed-signal applications.
All devices include a set of new advanced modules and
several existing analog peripherals, plus a common
voltage reference for ease of use.
The analog block includes four new modules:
• 12-Bit High-Speed, Pipeline A/D Converter
(described in Section 26.0 “12-Bit High-Speed,
Pipeline A/D Converter”)
• 16-Bit Sigma-Delta A/D (described
in Section 27.0 “16-Bit Sigma-Delta
Analog-to-Digital (A/D) Converter”)
• Dual 10-Bit Digital-to-Analog Converters
(described in Section 28.0 “10-Bit
Digital-to-Analog Converter (DAC)”)
• Dual Operational Amplifiers (described in
Section 29.0 “Dual Operational Amplifier
Module”)
It also includes these legacy PIC24F analog modules:
• Triple Comparator module (described in
Section 30.0 “Triple Comparator Module”) with
independent voltage reference (described in
Section 31.0 “Comparator Voltage Reference”)
• CTMU (described in Section 32.0 “Charge Time
Measurement Unit (CTMU)”)
A high-level overview of the analog block and its integrating features is shown in Figure 25-1. For a more
detailed diagram of each module and an explanation of
its operation, please refer to the appropriate chapter.
25.1
Shared Analog Pins
Apart from the reserved differential inputs for the
Sigma-Delta A/D Converter, PIC24FJ128GC010 family
devices may have up to 50 analog input channels (in
100-pin devices). Because of the number of analog
features available on the microcontroller, many of the
inputs and outputs of the other advanced analog
modules share pins with these channels.
Table 25-1 describes how features are multiplexed.
Note that not all of these analog channels and their
shared analog peripherals are available on all devices.
25.2
Internal Band Gap References
As an integrating feature, the analog block of the
PIC24FJ128GC010 family devices includes a common
internal voltage reference source. This band gap
provides several functions:
• A single, configurable internal reference source
(BGBUF0) for all on-chip analog consumers
• Two additional and independently programmable
band gap sources that can provide buffered
internal references (BGBUF1 and BGBUF2) to
external pins
• Independent configurability of all sources in Idle,
Sleep and other low-power modes, allowing for
flexibility in power consumption
The reference sources are controlled by three
registers: BUFCON0 for the internal reference
(Register 25-1), and BUFCON1 and BUFCON2
(Register 25-2) for the buffered references.
Additional information for using the analog peripherals
can be found in the following documents:
• AN1607, “PIC24FJ128GC010 Analog Design
Guide” (DS00001607)
• “Migrating to the New PIC24F Pipeline and
Sigma-Delta ADCs” (DS00001668)

12-BIT HIGH-SPEED, PIPELINE
A/D CONVERTER
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the
Pipeline A/D Converter, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “12-Bit, High-Speed Pipeline A/D
Converter” (DS30686). The information in
this data sheet supersedes the information
in the FRM.
The 12-bit Pipeline A/D Converter has the following key
features:
• Conversion Speeds of up to 10 Msps
• Up to 50 Analog Single-Ended Input Channels or
up to 15 Unique Differential Input Channel Pairs
• 12-Bit Conversion Resolution
• Multiple Internal Reference Input Channels
• External Voltage Reference Input Pins
• Automated Threshold Scan and Compare
Operation to Pre-Evaluate Conversion Results
• Extended Automated and Fully Programmable
Sampling Sequences from up to 4 Different Lists
• Conversion Result Accumulation
• Selectable Conversion Trigger Source
• Internal 32-Word, Configurable Conversion
Result Buffer
• Eight Options for Results Alignment
• Configurable Interrupt Generation
• Operation During CPU Sleep and Idle modes
The A/D Converter module is a 12-bit Pipeline A/D
Converter, capable of sampling up to once per A/D
clock cycle. Its operation is enhanced with a wide range
of automatic sampling options, tighter integration with
other analog modules, result accumulation across
many samples and a configurable results buffer.
A simplified block diagram for the module is shown in
Figure 26-1.
пѓЈ 2012-2014 Microchip Technology Inc.
26.1
Basic Operation
To perform a standard A/D conversion:
1.
Configure the module:
a) Configure port pins as analog inputs by
setting the appropriate bits in the ANSx registers (see Section 11.2 “Configuring Analog
Port Pins (ANSx)” for more information).
b) Configure “global” ADCON1, ADCON2 and
ADCON3 control settings, but do not set the
ADON bit until all global settings are
configured:
• Configure A/D clock source/rate
• Select A/D reference sources
• Configure data formatting
• Configure other settings
c) Enable the A/D module by setting the
ADON bit (ADCON1<15>).
d) Wait until the ADREADY bit (ADSTATH<1>)
becomes set, indicating the module is finished
with internal calibration and initialization.
e) Configure Sample List 0 settings, controlled
by the ADL0CONH and ADL0CONL registers, but do not enable the sample list yet
(SLEN):
• Select the desired sample list interrupt
generation settings
• Select a Data Write mode (ex: write all
results to buffer)
• Configure analog sampling time
(SAMC<4:0>)
• Select a trigger source
• Specify how many entries are in the
sample list (SLSIZE<4:0>)
• Configure other Sample List 0 specific
settings
f) Initialize the ADTBL0 register (and higher if
SLSIZEx > 0) to select the analog channel(s)
to be included in Sample List 0.
g) Configure and enable A/D interrupts (if
desired):
• Clear the AD1IF and SL0IF bits
• Select an interrupt priority
• Enable AD1IE
h) Enable Sample List 0 by setting the SLEN
bit (ADL0CONL<15>).
i) Generate a trigger event for Sample List 0
(as configured in Step e).
j) Wait for the SL0IF or top level AD1IF interrupt flag to assert, indicating that the A/D
result(s) are now ready.
k) Read the respective result(s) from the appropriate ADRESn register(s) (as configured
based on the BUFORG setting).
DS30009312C-page 351
PIC24FJ128GC010 FAMILY
26.2
Registers
The Pipeline A/D Converter uses a total of
116 registers. Of these, sixty-nine registers control the
module’s operations; the remainder are data and result
buffers.
Five “global” registers control overall module operation
and provide module status:
• ADCON1 through ADCON3 (Register 26-1
through Register 26-3)
• ADSTATH and ADSTATL (Register 26-4 and
Register 26-5)
Fifty-two registers control sample list selection,
configuration and execution:
• ADLnCONH and ADLnCONL (0 through 3)
(prototypes, Register 26-6 and Register 26-7)
• ADLnSTAT (0 through 3) (prototype, Register 26-8)
• ADLnPTR (0 through 3) (prototype, Register 26-9)
• ADLTLBn (0 through 31) (prototype, Register 26-10)
• ADLnMSEL0 through ADLnMSEL3 (0 through 3)
(prototypes, Register 26-17 through
Register 26-20)
Twelve registers control accumulator and threshold
detect operations:
• ACCONH and ACCONL (Register 26-11 and
Register 26-12)
• ADCHITH and ADCHITL (Register 26-13 and
Register 26-14)
• ADTHnH and ADTHnL (0 through 3) (prototypes,
Register 26-15 and Register 26-16)

2:
Use of the channel switch charge pump is recommended when AVDD < 2.5V.
When set, ADCAL remains set for at least one TAD and is then automatically cleared by hardware.
Manually clearing the bit does not necessarily cancel the calibration routine. Calibration is complete when
ADSTATH<1> = 1.

In order to use the BGBUF1 internal reference for the A/D, firmware must also configure and enable the
buffer through the BUFCON1 register.

27.1
Important Differences Compared
to Conventional A/D Converters
In principle, the Sigma-Delta A/D Converter does what
most other A/Ds do: it samples an analog input voltage
and generates a digital output code representing the
analog voltage. There are, however, a number of differences when comparing a Sigma-Delta Converter to conventional A/D Converters, such as the Successive
Approximation Register (SAR) design that is popular on
many of today’s microcontrollers.
The most important differences that are noticeable at
the application level include:
• Variable signal bandwidth based on the OSR
(Oversampling Ratio)
• Programmable input gain
• Uncorrected offset error
• Uncorrected gain error
27.1.1
RESULT QUALITY AND
OVERSAMPLING
In a typical application, involving switching digital
circuitry, oscillators, clocks and other noise sources
common in a microcontroller-based circuit, it is often
difficult to reduce the high-frequency noise floor below
some arbitrary value. For A/Ds, which perform
instantaneous “snapshot” based sampling (e.g.,
charging a Sample-and-Hold capacitor in a conventional
SAR-based A/D), this noise floor ultimately restricts the
maximum achievable stable result resolution.
To achieve higher effective stable resolution and to
minimize the effects of high-frequency noise, the
Sigma-Delta A/D Converter implements inherent oversampling in the design. This oversampling has an
effect similar to low-pass filtering of the analog signal
and voltage references to the A/D. Therefore, when the
converter generates a result, the output code represents the average voltage of the signal or reference
being measured over a specific time window, rather
than an instantaneous snapshot in time (like that of the
SAR-based A/D). This sampling method enables the
Sigma-Delta A/D Converter to generate stable results
at significantly higher resolution than is typically
achievable with conventional A/D designs.
DS30009312C-page 374
The design of this Sigma-Delta A/D Converter allows
user-configurable Oversampling Ratios (OSRs),
between 16 and 1024. The lowest settings provide the
fastest results, but they sacrifice result code accuracy.
The highest OSR settings provide the best quality and
most stable results, but generate results at a much
slower rate.
27.1.2
UNCORRECTED OFFSET ERROR
When uncorrected, the Sigma-Delta A/D Converter
typically has more LSBs worth of offset error than
conventional SAR-based A/Ds. This is partly due to the
high resolution and small size of each LSB. Additionally,
internal or external input circuitry, such as the internal
input gain stage, can also introduce some offset error.
Fortunately, the Sigma-Delta A/D Converter implements a feature that allows it to measure its own
internal offset error. This feature is controlled by the
VOSCAL bit (SD1CON1<4>). Once the application
firmware has measured the internal offset error, the
digital output code can be saved in the firmware and
subsequently subtracted from all future A/D measurements on the regular input channel(s). This procedure
significantly improves the absolute accuracy of the A/D
and is recommended for most applications.
27.1.3
UNCORRECTED GAIN ERROR
When uncorrected, Sigma-Delta A/D Converters
typically exhibit high gain error compared to other A/D
designs. To obtain high absolute accuracy from the
Sigma-Delta A/D Converter, it is necessary to compensate for both offset error and gain error. Gain error can
be corrected by first removing the offset error, then
multiplying the resulting code with a suitable gain error
correction factor.
One of the input channel settings selectable in the
SD1CON3 register allows the A/D to measure its own
references. When a measurement (with a gain of 1) is
performed on this channel, the result code can be corrected for offset error (using the method described in
Section 27.1.2 “Uncorrected Offset Error”) and then
used to calculate the gain error correction factor. Once
the gain error correction factor is known, it can be
saved and stored in the firmware, so that it may be
used later to correct for gain error when performing
measurements on the other A/D input channels.

PIC24FJ128GC010 family devices include two operational amplifiers to complement the microcontroller’s
other analog features. They may be used to provide
analog signal conditioning, either as stand-alone
devices or in addition to other analog peripherals. They
may also be configured to operate as digital comparators in addition to the triple comparator module (see
Section 30.0 “Triple Comparator Module” for more
information).

• Configurable as either an Operational Amplifier or
a Comparator
• Internal Unity-Gain Buffer Option
• Six Input Options each on the Inverting and
Non-Inverting Amplifier Inputs
• Rail-to-Rail Input and Output Capabilities
• User-Configurable Interrupt with Comparator
Operation, including Four Interrupt Options
• User-Selectable Option for Regular or
Low-Power Operation
• User-Selectable Operation in Idle and Sleep
modes
When using the op amps, it is recommended to set the
ANSx and TRISx bits of both the input and output pins
to configure them as analog pins. See Section 11.2

MODULE
Note:
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “Scalable Comparator Module”
(DS39734). The information in this data
sheet supersedes the information in the
FRM.
The triple comparator module provides three dual input
comparators. The inputs to the comparator can be
configured to use any one of five external analog inputs
(CxINA, CxINB, CxINC, CxIND and VREF+) and a
FIGURE 30-1:
The comparator outputs may be directly connected to
the CxOUT pins. When the respective COE equals �1’,
the I/O pad logic makes the unsynchronized output of
the comparator available on the pin.
A simplified block diagram of the module in shown in
Figure 30-1. Diagrams of the possible individual
comparator configurations are shown in Figure 30-2.
Each comparator has its own control register,
CMxCON (Register 30-1), for enabling and configuring
its operation. The output and event status of all three
comparators is provided in the CMSTAT register
(Register 30-2).

Configuring the Comparator
Voltage Reference
The voltage reference module is controlled through the
CVRCON register (Register 31-1). The comparator
voltage reference provides a range of output voltages,
with 32 distinct levels. The comparator reference supply voltage can come from either VDD and VSS, or the
external CVREF+ and CVREF- pins. The voltage source
is selected by the CVRSS bit (CVRCON<5>).
The settling time of the comparator voltage reference
must be considered when changing the CVREF
output.

CHARGE TIME
MEASUREMENT UNIT (CTMU)
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the
Charge Measurement Unit, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Charge Time Measurement Unit
(CTMU) with Threshold Detect”
(DS39743). The information in this data
sheet supersedes the information in the
FRM.
The Charge Time Measurement Unit (CTMU) is a flexible
analog module that provides charge measurement,
accurate differential time measurement between pulse
sources and asynchronous pulse generation. Its key
features include:
•
•
•
•
Thirteen External Edge Input Trigger Sources
Polarity Control for each Edge Source
Control of Edge Sequence
Control of Response to Edge Levels or
Edge Transitions
• Time Measurement Resolution of
One Nanosecond
• Accurate Current Source suitable for Capacitive
Measurement
Together with other on-chip analog modules, the CTMU
can be used to precisely measure time, measure
capacitance, measure relative changes in capacitance
or generate output pulses that are independent of the
system clock. The CTMU module is ideal for interfacing
with capacitive-based touch sensors.
The CTMU is controlled through three registers:
CTMUCON1, CTMUCON2 and CTMUICON.
CTMUCON1 enables the module and controls the
mode of operation of the CTMU, as well as controlling
edge sequencing. CTMUCON2 controls edge source
selection and edge source polarity selection. The
CTMUICON register selects the current range of
current source and trims the current.
пѓЈ 2012-2014 Microchip Technology Inc.
32.1
Measuring Capacitance
The CTMU module measures capacitance by
generating an output pulse with a width equal to the
time between edge events on two separate input
channels. The pulse edge events to both input
channels can be selected from four sources: two
internal peripheral modules (OC1 and Timer1) and up
to 13 external pins (CTEDG1 through CTEDG13). This
pulse is used with the module’s precision current
source to calculate capacitance according to the
relationship:
EQUATION 32-1:
dV
I = C пѓ— ------dT
For capacitance measurements, the A/D Converter
samples an external Capacitor (CAPP) on one of its input
channels after the CTMU output’s pulse. A Precision
Resistor (RPR) provides current source calibration on a
second A/D channel. After the pulse ends, the converter
determines the voltage on the capacitor. The actual
calculation of capacitance is performed in software by
the application.
Figure 32-1 illustrates the external connections used
for capacitance measurements, and how the CTMU
and A/D modules are related in this application. This
example also shows the edge events coming from
Timer1, but other configurations using external edge
sources are possible. A detailed discussion on
measuring capacitance and time with the CTMU
module is provided in the “dsPIC33/PIC24 Family Reference Manual”, “Charge Time Measurement Unit
(CTMU) with Threshold Detect”.
Note:
Only odd numbered ANx channels (AN1,
AN3, to AN15) are connected to the CTMU
during single-ended measurements.

Measuring Time
Time measurements on the pulse width can be similarly
performed using the A/D module’s internal Capacitor
(CAD) and a precision resistor for current calibration.
Figure 32-3 displays the external connections used for
time measurements, and how the CTMU and A/D
modules are related in this application. This example
also shows both edge events coming from the external
CTEDGx pins, but other configurations using internal
edge sources are possible.
32.3
Pulse Generation and Delay
The CTMU module can also generate an output pulse
with edges that are not synchronous with the device’s
system clock. More specifically, it can generate a pulse
with a programmable delay from an edge event input to
the module.
DS30009312C-page 394
When the module is configured for pulse generation
delay by setting the TGEN bit (CTMUCON1<12>), the
internal current source is connected to the B input of
Comparator 2. A Capacitor (CDELAY) is connected to
the Comparator 2 pin, C2INB, and the Comparator
Voltage Reference, CVREF, is connected to C2INA.
CVREF is then configured for a specific trip point. The
module begins to charge CDELAY when an edge event
is detected. When CDELAY charges above the CVREF
trip point, a pulse is output on CTPLS. The length of the
pulse delay is determined by the value of CDELAY and
the CVREF trip point.
Figure 32-4 illustrates the external connections for
pulse generation, as well as the relationship of the
different analog modules required. While CTED1 is
shown as the input pulse source, other options are
available. A detailed discussion on pulse generation
with the CTMU module is provided in the “dsPIC33/
PIC24 Family Reference Manual”.

32.4
Measuring Die Temperature
The CTMU can be configured to use the 12-bit Pipeline
A/D to measure the die temperature using dedicated
A/D Channel 50. Perform the following steps to
measure the diode voltage:
• The internal current source must be set for either
5.5 ВµA (IRNG<1:0> = 0x2) or 55 ВµA
(IRNG<1:0> = 0x3).
• In order to route the current source to the diode,
the EDG1STAT and EDG2STAT bits must be
equal (either both �0’ or both �1’).
• The CTMEN bit in the A/D sample list
(ADLnCONH<7>) must be set to �0’.
• Due to the high noise floor of the Pipeline A/D, it is
recommended to average at least 8 readings of
the diode voltage before calculating the
temperature.
• The A/D Channel Select bits must be 50 (0x32)
using a single-ended measurement.
The voltage of the diode will vary over temperature
according to the graphs shown below. Note that the
graphs are different, based on the magnitude of the
current source selected. The slopes are nearly linear
over the range of -40ВєC to +100ВєC and the temperature
can be calculated as follows:
EQUATION 32-2:
For 5.5 ВµA Current Source:
Tdie =
710 mV – Vdiode
1.8
where Vdiode is in mV, Tdie is in ВєC
For 55 ВµA Current Source:
Tdie =
760 mV – Vdiode
1.55
where Vdiode is in mV, Tdie is in ВєC

An interrupt flag is set if the device experiences an
excursion past the trip point in the direction of change.
If the interrupt is enabled, the program execution will
branch to the interrupt vector address and the software
can then respond to the interrupt.
HIGH/LOW-VOLTAGE DETECT
(HLVD)
Note:
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the
High/Low-Voltage Detect, refer to the
“dsPIC33/PIC24
Family
Reference
Manual”, “High-Level Integration with
Programmable High/Low-Voltage Detect
(HLVD)” (DS39725).
The HLVD Control register (see Register 33-1)
completely controls the operation of the HLVD module.
This allows the circuitry to be “turned off” by the user
under software control, which minimizes the current
consumption for the device.
The High/Low-Voltage Detect (HLVD) module is a
programmable circuit that allows the user to specify
both the device voltage trip point and the direction of
change.

SPECIAL FEATURES
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
following sections of the “dsPIC33/PIC24
Family Reference Manual”.
In PIC24FJ128GC010 family devices, the Configuration bytes are implemented as volatile memory. This
means that configuration data must be programmed
each time the device is powered up. Configuration data
is stored in the four words at the top of the on-chip
program memory space, known as the Flash Configuration Words. Their specific locations are shown in
Table 34-1. These are packed representations of the
actual device Configuration bits, whose actual
locations are distributed among several locations in
configuration space. The configuration data is automatically loaded from the Flash Configuration Words to the
proper Configuration registers during device Resets.
• “Watchdog Timer (WDT)”
(DS39697)
• “High-Level Device Integration”
(DS39719)
• “Programming and Diagnostics”
(DS39716)
The information in this data sheet
supersedes the information in the
FRMs.
Note:
PIC24FJ128GC010 family devices include several
features intended to maximize application flexibility and
reliability, and minimize cost through elimination of
external components. These are:
•
•
•
•
•
•
The upper byte of all Flash Configuration Words in
program memory should always be �0000 0000’. This
makes them appear to be NOP instructions in the
remote event that their locations are ever executed by
accident. Since Configuration bits are not implemented
in the corresponding locations, writing �0’s to these
locations has no effect on device operation.
Configuration Bits
The Configuration bits can be programmed (read as �0’),
or left unprogrammed (read as �1’), to select various
device configurations. These bits are mapped, starting
at program memory location, F80000h. A detailed explanation of the various bit functions is provided in
Register 34-1 through Register 34-6.
Note:
Note that address, F80000h, is beyond the user program
memory space. In fact, it belongs to the configuration
memory space (800000h-FFFFFFh), which can only be
accessed using Table Reads and Table Writes.
TABLE 34-1:
Configuration data is reloaded on every
device Reset.
When creating applications for these devices, users
should always specifically allocate the location of the
Flash Configuration Word for configuration data. This is
to make certain that program code is not stored in this
address when the code is compiled.

CONSIDERATIONS FOR
CONFIGURING PIC24FJ128GC010
FAMILY DEVICES
Performing a page erase operation on the
last page of program memory clears the
Flash Configuration Words, enabling code
protection as a result. Therefore, users
should avoid performing page erase
operations on the last page of program
memory.

PIC24FJ128GC010 FAMILY
34.2
On-Chip Voltage Regulator
All PIC24FJ128GC010 family devices power their core
digital logic at a nominal 1.8V. To simplify system
design, all devices in the PIC24FJ128GC010 family
incorporate an on-chip regulator that allows the device
to run its core logic from VDD.
This regulator is always enabled. It provides a constant
voltage (1.8V nominal) to the digital core logic, from a
VDD of 2.0V, all the way up to the device’s VDDMAX. It
does not have the capability to boost VDD levels. In
order to prevent “brown-out” conditions when the voltage drops too low for the regulator, the Brown-out
Reset occurs. Then the regulator output follows VDD
with a typical voltage drop of 300 mV.
A low-ESR capacitor (such as ceramic) must be
connected to the VCAP pin (Figure 34-1). This helps to
maintain the stability of the regulator. The recommended
value for the filter capacitor (CEFC) is provided in
Section 2.4 “Voltage Regulator Pin (VCAP)”.

This is a typical operating voltage. Refer to
Section 37.0 “Electrical Characteristics”
for the full operating ranges of VDD.
34.2.1
ON-CHIP REGULATOR AND POR
The voltage regulator requires a small amount of time
to transition from a disabled or standby state into normal operating mode. During this time, designated as
TVREG, code execution is disabled. TVREG is applied
every time the device resumes operation after any
power-down, including Sleep mode. TVREG is determined by the status of the PMSLP bit (RCON<8>).
Refer to Section 37.0 “Electrical Characteristics” for
more information on TVREG.
Note:
34.2.2
For more information, see Section 37.0
“Electrical Characteristics”. The Information in this data sheet supersedes the
information in the “dsPIC33/PIC24 Family
Reference Manual”.
VOLTAGE REGULATOR STANDBY
MODE
The on-chip regulator always consumes a small incremental amount of current over IDD/IPD, including when
the device is in Sleep mode, even though the core
digital logic does not require power. To provide additional savings in applications where power resources
are critical, the regulator can be made to enter Standby
mode on its own whenever the device goes into Sleep
mode. This feature is controlled by the PMSLP bit
(RCON<8>). Clearing the PMSLP bit enables the
Standby mode. When waking up from Standby mode,
the regulator needs to wait for TVREG to expire before
wake-up.
34.2.3
LOW-VOLTAGE/RETENTION
REGULATOR
When power-saving modes, such as Sleep and Deep
Sleep are used, PIC24FJ128GC010 family devices
may use a separate low-power, low-voltage/retention
regulator to power critical circuits. This regulator, which
operates at 1.2V nominal, maintains power to data
RAM and the RTCC while all other core digital logic is
powered down. It operates only in Sleep, Deep Sleep
and VBAT modes.
The low-voltage/retention regulator is described in
more detail in Section 10.1.3 “Low-Voltage/Retention
Regulator”.

34.3
Watchdog Timer (WDT)
For PIC24FJ128GC010 family devices, the WDT is
driven by the LPRC oscillator. When the WDT is
enabled, the clock source is automatically enabled.
The nominal WDT clock source is the LPRC (31 kHz).
This feeds a prescaler that can be configured for either
5-bit (divide-by-32) or 7-bit (divide-by-128) operation.
The prescaler is set by the FWPSA Configuration bit.
With a 31 kHz input, the prescaler yields a nominal
WDT Time-out period (TWDT) of 1 ms in 5-bit mode or
4 ms in 7-bit mode.
A variable postscaler divides down the WDT prescaler
output and allows for a wide range of time-out periods.
The postscaler is controlled by the WDTPS<3:0> Configuration bits (CW1<3:0>), which allows the selection
of a total of 16 settings, from 1:1 to 1:32,768. Using the
prescaler and postscaler time-out periods, ranges from
1 ms to 131 seconds can be achieved.
The WDT Flag bit, WDTO (RCON<4>), is not automatically cleared following a WDT time-out. To detect
subsequent WDT events, the flag must be cleared in
software.
Note:
34.3.1
The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.
WINDOWED OPERATION
The Watchdog Timer has an optional Fixed Window
mode of operation. In this Windowed mode, CLRWDT
instructions can only reset the WDT during the last 1/4
of the programmed WDT period. A CLRWDT instruction
executed before that window causes a WDT Reset,
similar to a WDT time-out.
Windowed WDT mode is enabled by programming the
WINDIS Configuration bit (CW1<5>) to �0’.
The WDT, prescaler and postscaler are reset:
34.3.2
• On any device Reset
• On the completion of a clock switch, whether
invoked by software (i.e., setting the OSWEN bit
after changing the NOSCx bits) or by hardware
(i.e., Fail-Safe Clock Monitor)
• When a PWRSAV instruction is executed
(i.e., Sleep or Idle mode is entered)
• When the device exits Sleep or Idle mode to
resume normal operation
• By a CLRWDT instruction during normal execution
The WDT is enabled or disabled by the FWDTEN<1:0>
Configuration bits. When the Configuration bits,
FWDTEN<1:0> = 11, the WDT is always enabled.
If the WDT is enabled, it will continue to run during
Sleep or Idle modes. When the WDT time-out occurs,
the device will wake the device and code execution will
continue from where the PWRSAV instruction was
executed. The corresponding SLEEP or IDLE
(RCON<3:2>) bit will need to be cleared in software
after the device wakes up.
FIGURE 34-2:
CONTROL REGISTER
The WDT can be optionally controlled in software when
the Configuration bits, FWDTEN<1:0> = 10. When
FWDTEN<1:0> = 00, the Watchdog Timer is always
disabled. The WDT is enabled in software by setting
the SWDTEN control bit (RCON<5>). The SWDTEN
control bit is cleared on any device Reset. The software
WDT option allows the user to enable the WDT for
critical Code Segments and disable the WDT during
non-critical segments for maximum power savings.

Program Verification and
Code Protection
PIC24FJ128GC010 family devices provide two complimentary methods to protect application code from
overwrites and erasures. These also help to protect the
device from inadvertent configuration changes during
run time.
34.4.1
GENERAL SEGMENT PROTECTION
For all devices in the PIC24FJ128GC010 family, the
on-chip program memory space is treated as a single
block, known as the General Segment (GS). Code protection for this block is controlled by one Configuration
bit, GCP. This bit inhibits external reads and writes to
the program memory space. It has no direct effect in
normal execution mode.
Write protection is controlled by the GWRP bit in the
Configuration Word. When GWRP is programmed to
�0’, internal write and erase operations to program
memory are blocked.
34.4.2
CODE SEGMENT PROTECTION
In addition to global General Segment protection, a
separate subrange of the program memory space can
be individually protected against writes and erases.
This area can be used for many purposes where a
separate block of write and erase-protected code is
needed, such as bootloader applications. Unlike
common boot block implementations, the specially
protected segment in the PIC24FJ128GC010 family
devices can be located by the user anywhere in the
program space and configured in a wide range of sizes.
Code Segment (CS) protection provides an added level
of protection to a designated area of program memory
by disabling the NVM safety interlock whenever a write
or erase address falls within a specified range. It does
not override General Segment protection, controlled by
the GCP or GWRP bit. For example, if GCP and GWRP
are enabled, enabling segmented code protection for
the bottom half of program memory does not undo
General Segment protection for the top half.
The size and type of protection for the segmented code
range are configured by the WPFPx, WPEND, WPCFG
and WPDIS bits in Configuration Word 3. Code Segment protection is enabled by programming the WPDIS
bit (= 0). The WPFPx bits specify the size of the
segment to be protected by specifying the 512-word
code page that is the start or end of the protected
segment. The specified region is inclusive, therefore,
this page will also be protected.
The WPEND bit determines if the protected segment
uses the top or bottom of the program space as a
boundary. Programming WPEND (= 0) sets the bottom
of program memory (000000h) as the lower boundary
of the protected segment. Leaving WPEND unprogrammed (= 1) protects the specified page through the
last page of implemented program memory, including
the Configuration Word locations.
A separate bit, WPCFG, is used to protect the last page
of program space, including the Flash Configuration
Words. Programming WPCFG (= 0) protects the last
page in addition to the pages selected by the WPEND
and WPFP<6:0> bits’ setting. This is useful in circumstances where write protection is needed for both the
Code Segment in the bottom of the memory and the
Flash Configuration Words.
The various options for Code Segment protection are
shown in Table 34-2.

34.4.3
CONFIGURATION REGISTER
PROTECTION
The Configuration registers are protected against
inadvertent or unwanted changes or reads in two ways.
The primary protection method is the same as that of
the RPn/RPIn registers – shadow registers contain a
complimentary value which is constantly compared
with the actual value.
To safeguard against unpredictable events, Configuration bit changes resulting from individual cell-level
disruptions (such as ESD events) will cause a parity
error and trigger a device Reset.
The data for the Configuration registers is derived from
the Flash Configuration Words in program memory.
When the GCP bit is set, the source data for device
configuration is also protected as a consequence. Even
if General Segment protection is not enabled, the
device configuration can be protected by using the
appropriate Code Segment protection setting.
34.5
JTAG Interface
PIC24FJ128GC010 family devices implement a JTAG
interface, which supports boundary scan device
testing.
DS30009312C-page 416
34.6
In-Circuit Serial Programmingв„ў
PIC24FJ128GC010 family microcontrollers can be
serially programmed while in the end application circuit.
This is simply done with two lines for clock (PGECx)
and data (PGEDx), and three other lines for power
(VDD), ground (VSS) and MCLR. This allows customers
to manufacture boards with unprogrammed devices
and then program the microcontroller just before
shipping the product. This also allows the most recent
firmware or a custom firmware to be programmed.
34.7
In-Circuit Debugger
When MPLABВ® ICD 3 is selected as a debugger, the
in-circuit debugging functionality is enabled. This function allows simple debugging functions when used with
MPLAB X IDE. Debugging functionality is controlled
through the PGECx (Emulation/Debug Clock) and
PGEDx (Emulation/Debug Data) pins.
To use the in-circuit debugger function of the device,
the design must implement ICSPв„ў connections to
MCLR, VDD, VSS and the PGECx/PGEDx pin pair,
designated by the ICSx Configuration bits. In addition,
when the feature is enabled, some of the resources are
not available for general use. These resources include
the first 80 bytes of data RAM and two I/O pins.

INSTRUCTION SET SUMMARY
This chapter is a brief summary of the
PIC24F Instruction Set Architecture (ISA)
and is not intended to be a comprehensive
reference source.
The PIC24F instruction set adds many enhancements
to the previous PICВ® MCU instruction sets, while maintaining an easy migration from previous PIC MCU
instruction sets. Most instructions are a single program
memory word. Only three instructions require two
program memory locations.
Each single-word instruction is a 24-bit word divided
into an 8-bit opcode, which specifies the instruction
type and one or more operands, which further specify
the operation of the instruction. The instruction set is
highly orthogonal and is grouped into four basic
categories:
•
•
•
•
• A literal value to be loaded into a W register or file
register (specified by the value of �k’)
• The W register or file register where the literal
value is to be loaded (specified by �Wb’ or �f’)
However, literal instructions that involve arithmetic or
logical operations use some of the following operands:
• The first source operand, which is a register, �Wb’,
without any address modifier
• The second source operand, which is a literal
value
• The destination of the result (only if not the same
as the first source operand), which is typically a
register, �Wd’, with or without an address modifier
The control instructions may use some of the following
operands:
• A program memory address
• The mode of the Table Read and Table Write
instructions
Word or byte-oriented operations
Bit-oriented operations
Literal operations
Control operations
Table 36-1 shows the general symbols used in
describing the instructions. The PIC24F instruction set
summary in Table 36-2 lists all the instructions, along
with the status flags affected by each instruction.
Most word or byte-oriented W register instructions
(including barrel shift instructions) have three
operands:
• The first source operand, which is typically a
register, �Wb’, without any address modifier
• The second source operand, which is typically a
register, �Ws’, with or without an address modifier
• The destination of the result, which is typically a
register, �Wd’, with or without an address modifier
However, word or byte-oriented file register instructions
have two operands:
• The file register specified by the value, �f’
• The destination, which could either be the file
register, �f’, or the W0 register, which is denoted
as �WREG’
Most bit-oriented instructions (including
rotate/shift instructions) have two operands:
The literal instructions that involve data movement may
use some of the following operands:
All instructions are a single word, except for certain
double-word instructions, which were made
double-word instructions so that all the required information is available in these 48 bits. In the second word,
the 8 MSbs are �0’s. If this second word is executed as
an instruction (by itself), it will execute as a NOP.
Most single-word instructions are executed in a single
instruction cycle, unless a conditional test is true or the
Program Counter is changed as a result of the instruction.
In these cases, the execution takes two instruction cycles,
with the additional instruction cycle(s) executed as a NOP.
Notable exceptions are the BRA (unconditional/computed
branch), indirect CALL/GOTO, all Table Reads and Writes,
and RETURN/RETFIE instructions, which are single-word
instructions but take two or three cycles.
Certain instructions that involve skipping over the subsequent instruction require either two or three cycles if
the skip is performed, depending on whether the
instruction being skipped is a single-word or two-word
instruction. Moreover, double-word moves require
two cycles. The double-word instructions execute in
two instruction cycles.
simple
• The W register (with or without an address
modifier) or file register (specified by the value of
�Ws’ or �f’)
• The bit in the W register or file register
(specified by a literal value or indirectly by the
contents of register, �Wb’)

The original “USB 2.0 Specification” indicated that USB devices should withstand 24-hour short circuits of
D+ or D- to VBUS voltages. This requirement was later removed in an Engineering Change Notice (ECN)
supplement to the USB specifications, which supersedes the original specifications. PIC24FJ128GC010
family devices will typically be able to survive this short-circuit test, but it is recommended to adhere to the
absolute maximum specified here to avoid damaging the device.
Maximum allowable current is a function of device maximum power dissipation (see Table 37-1).
†NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above
those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions
for extended periods may affect device reliability.

The supply current is mainly a function of the operating voltage and frequency. Other factors, such as I/O
pin loading and switching rate, oscillator type, internal code execution pattern and temperature, also have
an impact on the current consumption. No peripheral modules are operating and all of the Peripheral

Data in the “Typ” column is at 3.3V, +25°C unless otherwise stated.
Represents input to the system clock prescaler. PLL dividers and postscalers must still be configured so
that the system clock frequency does not exceed the maximum frequency shown in Figure 37-1.
Instruction cycle period (TCY) equals two times the input oscillator time base period. All specified values are
based on characterization data for that particular oscillator type, under standard operating conditions, with
the device executing code. Exceeding these specified limits may result in an unstable oscillator operation
and/or higher than expected current consumption. All devices are tested to operate at “Min.” values with an
external clock applied to the OSCI/CLKI pin. When an external clock input is used, the “Max.” cycle time
limit is “DC” (no clock) for all devices.
Measurements are taken in EC mode. The CLKO signal is measured on the OSCO pin. CLKO is low for the
Q1-Q2 period (1/2 TCY) and high for the Q3-Q4 period (1/2 TCY).

To achieve this accuracy, physical stress applied to the microcontroller package (ex., by flexing the PCB)
must be kept to a minimum.
Accuracy measured with respect to reference source accuracy.
Time from reference clock is stable and in range until the FRC is tuned within the range specified by F20
(with self-tune).
Other frequencies that are derived from the FRC (either through digital division by prescalers or multiplication
through a PLL) will also have the same accuracy tolerance specifications as provided here.

The A/D conversion result never decreases with an increase in the input voltage.
Measurements are taken with the external AVREF+ and AVREF- used as the A/D voltage reference.
Overall accuracy can be improved if 4 or more consecutive measurements are averaged. For details, see
the “dsPIC33/PIC24 Family Reference Manual”, “12-Bit, High-Speed Pipeline A/D Converter”
(DS30686).
