dsPIC33F DEVICE FAMILY
OVERVIEW
The dsPIC33F device family employs a powerful 16-bit
architecture that seamlessly integrates the control
features of a Microcontroller (MCU) with the
computational capabilities of a Digital Signal Processor
(DSP). The resulting functionality is ideal for
applications that rely on high-speed, repetitive
computations, as well as control.
The DSP engine, dual 40-bit accumulators, hardware
support for division operations, barrel shifter, 17 x 17
multiplier, a large array of 16-bit working registers and
FIGURE 2-1:
a wide variety of data addressing modes, together
provide the dsPIC33F Central Processing Unit (CPU)
with extensive mathematical processing capability.
Flexible and deterministic interrupt handling, coupled
with a powerful array of peripherals, renders the
dsPIC33F devices suitable for control applications.
Further, Direct Memory Access (DMA) enables
overhead-free transfer of data between several
peripherals and a dedicated DMA RAM. Reliable, field
programmable Flash program memory ensures
scalability of applications that use dsPIC33F devices.
Figure 2-1 shows a sample device block diagram
typical of the dsPIC33F product family.

dsPIC33F
3.1
Overview
FIGURE 3-1:
The dsPIC33F CPU module has a 16-bit (data)
modified Harvard architecture with an enhanced
instruction set, including significant support for DSP.
The CPU has a 24-bit instruction word with a variable
length opcode field. The Program Counter (PC) is
23 bits wide and addresses up to 4M x 24 bits of user
program memory space. The actual amount of program
memory implemented, as illustrated in Figure 3-1,
varies from one device to another. 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 DO
and REPEAT instructions, both of which are
interruptible at any point.

The dsPIC33F instruction set has two classes of
instructions: the MCU class of instructions and the DSP
class of instructions. These two instruction classes are
seamlessly integrated into a single CPU. The
instruction set includes many addressing modes and is
designed for optimum C compiler efficiency.
DATA MEMORY OVERVIEW
Configuration Memory
Space
Reserved
The data space can be addressed as 32K words or
64 Kbytes and is split into two blocks, referred to as X
and Y data memory. Each memory block has its own
independent Address Generation Unit (AGU). The
MCU class of instructions operates solely through the
X memory AGU, which accesses the entire memory
map as one linear data space. Certain DSP instructions
operate through the X and Y AGUs to support dual
operand reads, which splits the data address space
into two parts. The X and Y data space boundary is
device specific.
The upper 32 Kbytes of the data space memory map
can optionally be mapped into program space at any
16K program word boundary defined by the 8-bit
Program Space Visibility Page (PSVPAG) register. The
program-to-data space mapping feature lets any
instruction access program space as if it were data
space.
The data space includes 2 Kbytes of DMA RAM, which
is primarily used for DMA data transfers, but may be
used as general purpose RAM.

Program Memory
(87296 x 24-bit)
The dsPIC33F devices have sixteen 16-bit working
registers in the programmer’s model. Each of the
working registers can serve as a data, address or
address offset register. The 16th working register
(W15) operates as a software Stack Pointer (SP) for
interrupts and calls.

ADDRESSING MODES OVERVIEW
Overhead-free circular buffers (modulo addressing) are
supported in both X and Y address spaces. The
modulo addressing removes the software boundary
checking overhead for DSP algorithms. Furthermore,
the X AGU circular addressing can be used with any of
the MCU class of instructions. The X AGU also
supports bit-reversed addressing to greatly simplify
input or output data reordering for radix-2 FFT
algorithms.
The CPU supports Inherent (no operand), Relative,
Literal, Memory Direct, Register Direct and Register
Indirect Addressing modes. Each instruction is
associated with a predefined addressing mode group
depending upon its functional requirements. As many
as 6 addressing modes are supported for each
instruction.
For most instructions, the dsPIC33F 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 A + B = C operations to be
executed in a single cycle.
3.1.3
DSP ENGINE OVERVIEW
The dsPIC33F supports 16/16 and 32/16 divide
operations, both fractional and integer. All divide
instructions are iterative operations. They must be
executed within a REPEAT loop, resulting in a total
execution time of 19 instruction cycles. The divide
operation can be interrupted during any of those 19
cycles without loss of data.
A 40-bit barrel shifter is used to perform up to a 16-bit
left or right shift in a single cycle. The barrel shifter can
be used by both MCU and DSP instructions.
3.1.5
The dsPIC33F has a vectored exception scheme with
up to 5 sources of non-maskable traps and 67 interrupt
sources. Each interrupt source can be assigned to one
of seven priority levels.

SPECIAL MCU FEATURES
The dsPIC33F features a 17-bit by 17-bit, single-cycle
multiplier that is shared by both the MCU ALU and DSP
engine. The multiplier can perform signed, unsigned
and mixed-sign multiplication. Using a 17-bit by 17-bit
multiplier for 16-bit by 16-bit multiplication not only
allows you to perform mixed-sign multiplication, it also
achieves accurate results for special operations such
as (-1.0) x (-1.0).

FEATURES TO ENHANCE
COMPILER EFFICIENCY
In addition to extensive DSP capability, the CPU
architecture possesses several features that lead to a
more efficient (code size and speed) C compiler.
2.
The DSP engine features a high-speed, 17-bit by 17-bit
multiplier, a 40-bit ALU, two 40-bit saturating
accumulators and a 40-bit bidirectional barrel shifter.
The barrel shifter is capable of shifting a 40-bit value,
up to 16 bits right or left, in a single cycle. The DSP
instructions operate seamlessly with all other
instructions and have been designed for optimal realtime performance. The MAC instruction and other
associated instructions can concurrently fetch two data
operands from memory while multiplying two W
registers and accumulating and optionally saturating
the result in the same cycle. This instruction
functionality requires that the RAM memory data space
be split for these instructions and linear for all others.
Data space partitioning is achieved in a transparent
and flexible manner through dedicating certain working
registers to each address space.
INTERRUPT OVERVIEW
Preliminary
For most instructions, three-parameter instructions can be supported, allowing A + B = C
operations to be executed in a single cycle.
Instruction addressing modes are extremely
flexible to meet compiler needs.
The working register array consists of 16 x 16-bit
registers, each of which can act as data,
address or offset registers. One working register
(W15) operates as the software Stack Pointer
for interrupts and calls.
Linear indirect access of all data space is
possible, plus the memory direct address range
is up to 8 Kbytes. This capability, together with
the addition of 16-bit direct address MOV-based
instructions, has provided a contiguous linear
addressing space.
Linear indirect access of 32K word (64 Kbyte)
pages within program space is possible, using
any working register via new table read and
write instructions.
Part of data space can be mapped into program
space, allowing constant data to be accessed as
if it were in data space.

3.2
Programmer’s Model
The programmer’s model, shown in Figure 3-2,
consists of 16 x 16-bit working registers (W0 through
W15), 2 x 40-bit accumulators (ACCA and ACCB),
Status Register (SR), Data Table Page register
(TBLPAG), Program Space Visibility Page register
(PSVPAG), DO and REPEAT registers (DOSTART,
DOEND, DCOUNT and RCOUNT) and Program
Counter (PC). The working registers can act as data,
address or offset registers. All registers are memory
mapped. W0 is the W register for all instructions that
perform file register addressing.
Some of these registers have a shadow register
associated with them (see the legend in Figure 3-2).
The shadow register is used as a temporary holding
register and can transfer its contents to or from its host
register upon some event occurring in a single cycle.
None of the shadow registers are accessible directly.
W15 is the dedicated software Stack Pointer (SP). It is
automatically modified by exception processing and
subroutine calls and returns. However, W15 can be
referenced by any instruction in the same manner as all
other W registers. This simplifies the reading, writing
and manipulation of the Stack Pointer (e.g., creating
stack frames).
W14 has been dedicated as a Stack Frame Pointer, as
defined by the LNK and ULNK instructions. However,
W14 can be referenced by any instruction in the same
manner as all other W registers.
The Stack Pointer always points to the first available
free word and grows from lower addresses towards
higher addresses. It pre-decrements for stack pops
(reads) and post-increments for stack pushes (writes).
When a byte operation is performed on a working
register, only the Least Significant Byte of the target
register is affected. However, a benefit of memory
mapped working registers is that both the Least and
Most Significant Bytes can be manipulated through
byte-wide data memory space accesses.

3.3.3
Data Address Space
The core has two data spaces, X and Y. These data
spaces can be considered either separate (for some
DSP instructions), or as one unified linear address
range (for MCU instructions). The data spaces are
accessed using two Address Generation Units (AGUs)
and separate data paths. This feature allows certain
instructions to concurrently fetch two words from RAM,
thereby enabling efficient execution of DSP algorithms
such as Finite Impulse Response (FIR) filtering and
Fast Fourier Transform (FFT).
3.3.1
X AND Y DATA SPACES
The X data space is used by all instructions and
supports all addressing modes. There are separate
read and write data buses for X data space. The X read
data bus is the read data path for all instructions that
view data space as combined X and Y address space.
It is also the X data prefetch path for the dual operand
DSP instructions (MAC class).
The Y data space is used in concert with the X data
space by the MAC class of instructions (CLR, ED,
EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to
provide two concurrent data read paths.
Both the X and Y data spaces support Modulo
Addressing for all instructions, subject to addressing
mode restrictions. Bit-Reversed Addressing is only
supported for writes to X data space.
All data memory writes, including in DSP instructions,
view data space as combined X and Y address space.
The boundary between the X and Y data spaces is
device-dependent (an example is shown in Figure 3-3)
and is not user-programmable.
DATA SPACE WIDTH
The core data width is 16 bits. All internal registers are
organized as 16-bit wide words. Data space memory is
organized in byte addressable, 16-bit wide blocks.
Figure 3-3 depicts a sample data space memory map
for the dsPIC33F device with 33 Kbytes of RAM.
3.3.4
DATA ALIGNMENT
To help maintain backward compatibility with
PICmicro® devices and improve data space memory
usage efficiency, the dsPIC33F instruction set supports
both word and byte operations. Data is aligned in data
memory and registers as words, but all data space EAs
resolve to bytes. Data byte reads will read the complete
word which contains the byte, using the Least
Significant bit (LSb) of any EA to determine which byte
to select.
As a consequence of this byte accessibility, all effective
address calculations are internally scaled. For
example, the core would recognize 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.
All word accesses must be aligned to an even address.
Misaligned word data fetches are not supported.
Should a misaligned read or write be attempted, a trap
will then be executed, allowing the system and/or user
to examine the machine state prior to execution of the
address Fault.
All effective addresses are 16 bits wide and point to
bytes within the data space. Therefore, the data space
address range is 64 Kbytes or 32K words, though the
implemented memory locations vary from one device to
another.
3.3.2
DMA RAM
Every dsPIC33F device contains 2 Kbytes of DMA RAM
located at the end of Y data space. Memory locations in
the DMA RAM space are accessible simultaneously by
the CPU and the DMA Controller module. DMA RAM is
utilized by the DMA Controller to store data to be
transferred to various peripherals using DMA, as well as
data transferred from various peripherals using DMA.
When the CPU and the DMA Controller attempt to
concurrently write to the same DMA RAM location, the
hardware ensures that the CPU is given precedence in
accessing the DMA RAM location. Therefore, the DMA
RAM provides a reliable means of transferring DMA
data without ever having to stall the CPU.

3.4.3
DSP Engine
The DSP engine consists of a high-speed, singlecycle, 17-bit x 17-bit multiplier, a barrel shifter and a
40-bit adder/subtractor with two target accumulators,
round and saturation logic, all of which enable efficient
execution of computationally intensive DSP
algorithms. The 17-bit x 17-bit multiplier is also utilized
for MCU-based multiply instructions.
The DSP engine also has the capability to perform
inherent accumulator-to-accumulator operations, which
require no additional data. These instructions are ADD,
SUB and NEG. This feature greatly simplifies basic
arithmetic operations on 32-bit or 40-bit data.
A block diagram of the DSP engine is shown in
Figure 3-4.
3.4.1
17 x 17-BIT MULTIPLIER
The 17 x 17-bit multiplier is capable of signed or
unsigned operation. It can suitably scale its output to
support either 1.31 fractional (Q31) or 32-bit integer
results, thereby diminishing the need to manually
post-process multiplication results for fractional data.
3.4.2
SATURATION AND OVERFLOW
The adder has an additional saturation block that
controls accumulator data saturation, if selected. It
uses the result of the adder, the overflow status bits
described above and the user-configured control bits to
determine when to saturate and to what value to
saturate (a 40-bit or a 32-bit value).
In addition to adder/subtractor saturation, writes to data
space can also be saturated, but without affecting the
contents of the source accumulator.
The rounding logic performs a conventional (biased) or
convergent (unbiased) data rounding function during
an accumulator write (store). The Round mode is userselectable. Rounding generates a 16-bit, 1.15 data
value, which is passed to the data space write
saturation logic. Data space write saturation ensures
that the data in the accumulator is written back
accurately even when rounding is performed. If
rounding is not indicated by the instruction, a truncated
1.15 data value is stored and the least significant word
is simply discarded.
40-BIT ACCUMULATORS
The data accumulators have a 40-bit adder/subtractor
with automatic sign extension logic. It can select one of
two accumulators (A or B) as its pre-accumulation
source and post-accumulation destination. For the ADD
and LAC instructions, the data to be accumulated or
loaded can be optionally scaled via the barrel shifter
prior to accumulation.
The adder/subtractor generates overflow status bits,
SA/SB and OA/OB, which are latched and reflected in
the Status register and can also optionally generate an
arithmetic error trap:
• Overflow from bit 39. This is a catastrophic
overflow in which the sign of the accumulator is
destroyed.
• Overflow into guard bits 32 through 39. This is a
recoverable overflow. This bit (OA/OB) is set
whenever all the guard bits are not identical to
each other.

DIRECT MEMORY ACCESS
• Indirect addressing of DMA RAM locations with or
without automatic post-increment
• Peripheral Indirect Addressing – In some
peripherals, the DMA RAM read/write addresses
may be partially derived from the peripheral
• One-Shot Block Transfers – Terminating DMA
transfer after one block transfer
• Continuous Block Transfers – Reloading DMA
RAM buffer start address after every block
transfer is complete
• Ping-Pong Mode – Switching between two DMA
RAM start addresses between successive block
transfers, thereby filling two buffers alternately
• Automatic or manual initiation of block transfers
• Each channel can select from 32 possible
sources of data sources or destinations
Direct Memory Access (DMA) is a very efficient
mechanism of copying data between peripheral SFRs
(e.g., UART Receive register, Input Capture 1 buffer)
and buffers or variables stored in RAM with minimal
CPU intervention. The DMA Controller can
automatically copy entire blocks of data, without the
user software having to read or write peripheral Special
Function Registers (SFRs) every time a peripheral
interrupt occurs. To exploit the DMA capability, the
corresponding user buffers or variables must be
located in DMA RAM space.
The DMA Controller features eight identical data
transfer channels, each with its own set of control and
status registers. The UART, SPI, DCI, Input Capture,
Output Compare, ECAN™ and A/D modules can utilize
DMA. Each DMA channel can be configured to copy
data either from buffers stored in DMA RAM to
peripheral SFRs or from peripheral SFRs to buffers in
DMA RAM.
For each DMA channel, a DMA interrupt request is
generated when a block transfer is complete.
Alternatively, an interrupt can be generated when half of
the block has been filled. Additionally, a DMA error trap
is generated in either of the following Fault conditions:
Each channel supports the following features:
• DMA RAM data write collision between the CPU
and a peripheral
• Peripheral SFR data write collision between the
CPU and the DMA Controller
• Word or byte-sized data transfers
• Transfers from peripheral to DMA RAM or DMA
RAM to peripheral

EXCEPTION PROCESSING
The dsPIC33F has four processor exceptions (traps)
and up to 67 sources of interrupts, which must be
arbitrated based on a priority scheme.
The processor core is responsible for reading the
Interrupt Vector Table (IVT) and transferring the
address contained in the interrupt vector to the
program counter.
Each individual interrupt source has its own vector
address and can be individually enabled and prioritized
in user software. Each interrupt source also has its own
status flag. This independent control and monitoring of
the interrupt eliminates the need to poll various status
flags to determine the interrupt source
Table 5-1 contains information about the interrupt
vector.
The Interrupt Vector Table (IVT) and Alternate Interrupt
Vector Table (AIVT) are placed near the beginning of
program memory (0x000004) for ease of debugging.
Certain interrupts have specialized control bits for
features like edge or level triggered interrupts, interrupton-change, etc. Control of these features remains within
the peripheral module, which generates the interrupt.
The interrupt controller hardware pre-processes the
interrupts before they are presented to the CPU.
The interrupts and traps are enabled, prioritized and
controlled using centralized Special Function Registers.
The special DISI instruction can be used to disable
the processing of interrupts of priorities 6 and lower for
a certain number of instruction cycles, during which
the DISI bit remains set.

5.1
Interrupt Priority
5.3
Each interrupt source can be user-assigned to one of
8 priority levels, 0 through 7. Levels 7 and 1 represent
the highest and lowest maskable priorities,
respectively. A priority level of 0 disables the interrupt.
Since more than one interrupt request source may be
assigned to a user-specified priority level, a means is
provided to assign priority within a given level. This
method is called “Natural Order Priority”.
The Natural Order Priority of an interrupt is numerically
identical to its vector number. The Natural Order
Priority scheme has 0 as the highest priority and 74 as
the lowest priority.
The ability for the user to assign every interrupt to one
of eight priority levels implies that the user can assign
a very high overall priority level to an interrupt with a
low Natural Order Priority, thereby providing much
flexibility in designing applications that use a large
number of peripherals.
5.2
Interrupt Nesting
Interrupts, by default, are nestable. Any ISR that is in
progress may be interrupted by another source of
interrupt with a higher user-assigned priority level.
Interrupt nesting may be optionally disabled by
setting the NSTDIS control bit (INTCON1<15>).
When the NSTDIS control bit is set, all interrupts in
progress will force the CPU priority to level 7 by
setting IPL<2:0> = 111. This action will effectively
mask all other sources of interrupt until a RETFIE
instruction is executed. When interrupt nesting is
disabled, the user-assigned interrupt priority levels
will have no effect, except to resolve conflicts
between simultaneous pending interrupts.
The IPL<2:0> bits become read-only when interrupt
nesting is disabled. This prevents the user software
from setting IPL<2:0> to a lower value, which would
effectively re-enable interrupt nesting.
TABLE 5-2:
Traps
Traps can be considered as non-maskable, nestable
interrupts that adhere to a fixed priority structure.
Traps are intended to provide the user a means to
correct erroneous operation during debug and when
operating within the application. If the user does not
intend to take corrective action in the event of a trap
error condition, these vectors must be loaded with the
address of a software routine that will reset the device.
Otherwise, the trap vector is programmed with the
address of a service routine that will correct the trap
condition.
The dsPIC33F has four implemented sources of
non-maskable traps:
•
•
•
•
•
Oscillator Failure Trap
Address Error Trap
Stack Error Trap
Math Error Trap
DMA Trap
Many of these trap conditions can only be detected
when they happen. Consequently, the instruction that
caused the trap is allowed to complete before
exception processing begins. Therefore, the user may
have to correct the action of the instruction that
caused the trap.
Each trap source has a fixed priority as defined by its
position in the IVT. An oscillator failure trap has the
highest priority, while an arithmetic error trap has the
lowest priority.
Table 5-2 contains information about the trap vector.
5.4
Generating a Software Interrupt
Any available interrupt can be manually generated by
user software (even if the corresponding peripheral is
disabled), simply by enabling the interrupt and then
setting the interrupt flag bit when required.

System management services provided by the
dsPIC33F device family include:

Oscillator Start-up Timer/Stabilizer
Watchdog Timer with RC oscillator
Fail-Safe Clock Monitor

6.1
Clock Options and Oscillators
There are 7 clock options provided by the dsPIC33F:
•
•
•
•
•
•
FRC Oscillator
FRC Oscillator with PLL
Primary (XT, HS or EC) Oscillator
Primary Oscillator with PLL
Secondary (LP) Oscillator
LPRC Oscillator
The primary oscillator can use one of the following as
its clock source:
2.
3.
The output of the oscillator (or the output of the PLL if
a PLL mode has been selected) is divided by 4 to
generate the device instruction clock (FCY). FCY
defines the operating speed of the device, and speeds
up to 40 MHz are supported by the dsPIC33F
architecture.
The dsPIC33F oscillator system provides:
The FRC (Fast RC) internal oscillator runs at a nominal
frequency of 7.37 MHz. The user software can tune the
FRC frequency. User software can specify a factor by
which this clock frequency is scaled.
1.
The clock signals generated by the FRC and primary
oscillators can be optionally applied to an on-chip
Phase Locked Loop (PLL) to provide a wide range of
output frequencies for device operation. The input to
the PLL can be in the range of 1.6 MHz to 16 MHz, and
the PLL Phase Detector Input Divider, PLL Multiplier
Ratio and PLL Voltage Controlled Oscillator (VCO) can
be individually configured by user software to generate
output frequencies in the range of 25 MHz to 160 MHz.
XT (Crystal): Crystals and ceramic resonators in
the range of 3 MHz to 10 MHz. The crystal is
connected to the OSC1 and OSC2 pins.
HS (High-Speed Crystal): Crystals in the range
of 10 MHz to 40 MHz. The crystal is connected
to the OSC1 and OSC2 pins.
EC (External Clock): External clock signal in the
range of 0.8 MHz to 64 MHz. The external clock
signal is directly applied to the OSC1 pin.
• Various external and internal oscillator options as
clock sources
• An on-chip PLL to scale the internal operating
frequency to the required system clock frequency
• The internal FRC oscillator can also be used with
the PLL, thereby allowing full-speed operation
without any external clock generation hardware
• Clock switching between various clock sources
• Programmable clock postscaler for system power
savings
• A Fail-Safe Clock Monitor (FSCM) that detects
clock failure and takes fail-safe measures
• A Clock Control register (OSCCON)
• Nonvolatile configuration bits for main oscillator
selection.
A simplified block diagram of the oscillator system is
shown in Figure 6-1.
The secondary (LP) oscillator is designed for low power
and uses a 32 kHz crystal or ceramic resonator. The LP
oscillator uses the SOSCI and SOSCO pins.
The LPRC (Low-Power RC) internal oscIllator runs at a
nominal frequency of 32.768 kHz. Another scaled
reference clock is used by the Watchdog Timer (WDT)
and Fail-Safe Clock Monitor (FSCM).

Power-on Reset
6.4
When a supply voltage is applied to the device, a
Power-on Reset is generated. A new Power-on Reset
event is generated if the supply voltage falls below the
device threshold voltage (VPOR). An internal POR
pulse is generated when the rising supply voltage
crosses the POR circuit threshold voltage.
6.3
Oscillator Start-up Timer/Stabilizer
(OST)
An Oscillator Start-up Timer (OST) is included to
ensure that a crystal oscillator (or ceramic resonator)
has started and stabilized. The OST is a simple, 10-bit
counter that counts 1024 TOSC cycles before releasing
the oscillator clock to the rest of the system. The timeout period is designated as TOST. The TOST time is
involved every time the oscillator has to restart (i.e., on
Power-on Reset (POR) and wake-up from Sleep). The
Oscillator Start-up Timer is applied to the LP oscillator,
XT and HS modes (upon wake-up from Sleep, POR
and BOR) for the primary oscillator.
DS70155C-page 20
Watchdog Timer (WDT)
The primary function of the Watchdog Timer (WDT) is
to reset the processor in the event of a software
malfunction. The WDT is a free-running timer that runs
off the on-chip LPRC oscillator, requiring no external
component. The WDT continues to operate even if the
main processor clock (e.g., the crystal oscillator) fails.
The Watchdog Timer can be “Enabled” or “Disabled”
either through a configuration bit (FWDTEN) in the
Configuration register, or through an SFR bit
(SWDTEN).
Any device programmer capable of programming
dsPIC® DSC devices (such as Microchip’s MPLAB®
PM3 Programmer) allows programming of this and
other configuration bits to the desired state. If enabled,
the WDT increments until it overflows or “times out”. A
WDT time-out forces a device Reset (except during
Sleep).

6.5
Fail-Safe Clock Monitor (FSCM)
6.6
The Fail-Safe Clock Monitor (FSCM) allows the device
to continue to operate even in the event of an oscillator
failure. The FSCM function is enabled by programming.
If the FSCM function is enabled, the LPRC internal
oscillator runs at all times (except during Sleep mode)
and is not subject to control by the Watchdog Timer.
In the event of an oscillator failure, the FSCM
generates a clock failure trap event and switches the
system clock over to the FRC oscillator. The application
program then can either attempt to restart the oscillator,
or execute a controlled shutdown. The trap can be
treated as a warm Reset by simply loading the Reset
address into the oscillator fail trap vector.

The Reset system combines all Reset sources and
controls the device Master Reset signal.
Device Reset sources include:
•

DEVICE POWER MANAGEMENT
Power management services
dsPIC33F devices include:
provided
by
the
• Real-Time Clock Source Switching
• Power-Saving Modes
The processor exits (wakes up) from Sleep on one of
these events:
• Any interrupt source that is individually enabled
• Any form of device Reset
• A WDT time-out
7.2.2
7.1
Real-Time Clock Source Switching
Configuration bits determine the clock source upon
Power-on Reset (POR) and Brown-out Reset (BOR).
Thereafter, the clock source can be changed between
permissible clock sources. The OSCCON register
controls the clock switching and reflects system clock
related status bits. To reduce power consumption, the
user can switch to a slower clock source.
7.2
Power-Saving Modes
The dsPIC33F devices have two reduced power
modes that can be entered through execution of the
PWRSAV instruction.
• Sleep Mode: The CPU, system clock source and
any peripherals that operate on the system clock
source are disabled. This is the lowest power
mode of the device.
• Idle Mode: The CPU is disabled but the system
clock source continues to operate. Peripherals
continue to operate but can optionally be disabled.
• Doze Mode: The CPU clock is temporarily slowed
down relative to the peripheral clock by a
user-selectable factor.
These modes provide an effective way to reduce power
consumption during periods when the CPU is not in use.
7.2.1
SLEEP MODE
When the device enters Sleep mode:
• System clock source is shut down. If an on-chip
oscillator is used, it is turned off.
• Device current consumption is at minimum
provided that no I/O pin is sourcing current.
• Fail-Safe Clock Monitor (FSCM) does not operate
during Sleep mode because the system clock
source is disabled.
• LPRC clock continues to run in Sleep mode if the
WDT is enabled.
• BOR circuit, if enabled, remains operative during
Sleep mode
• WDT, if enabled, is automatically cleared prior to
entering Sleep mode.
• Some peripherals may continue to operate in
Sleep mode. These peripherals include I/O pins
that detect a change in the input signal, or
peripherals that use an external clock input. Any
peripheral that is operating on the system clock
source is disabled in Sleep mode.
DS70155C-page 22
Preliminary
IDLE MODE
When the device enters Idle mode:
•
•
•
•
CPU stops executing instructions
WDT is automatically cleared
System clock source remains active
Peripheral modules, by default, continue to
operate normally from the system clock source
• Peripherals, optionally, can be shut down in Idle
mode using their ‘stop-in-idle’ control bit.
• If the WDT or FSCM is enabled, the LPRC also
remains active
The processor wakes from Idle mode on these events:
• Any interrupt that is individually enabled
• Any source of device Reset
• A WDT time-out
Upon wake-up from Idle, the clock is re-applied 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).
7.2.3
DOZE MODE
The Doze mode provides the user software the ability
to temporarily reduce the processor instruction cycle
frequency relative to the peripheral frequency. Clock
frequency ratios of 1:1, 1:2, 1:4, 1:8, 1:16, 1:32, 1:64
and 1:128 are supported.
For example, suppose the device is operating at
20 MIPS and the CAN module has been configured for
500 kbps bit rate based on this device operating speed.
If the device is now placed in Doze mode with a clock
frequency ratio of 1:4, the CAN module will continue to
communicate at the required bit rate of 500 kbps, but
the CPU now starts executing instructions at a
frequency of 5 MIPS.
This feature further reduces the power consumption
during periods where relatively less CPU activity is
required.
When the device is operating in Doze mode, the
hardware ensures that there is no loss of
synchronization between peripheral events and SFR
accesses by the CPU.

Quadrature Encoder Interface
(QEI) Module
increment when the shaft is rotating one direction and
decrement when the shaft is rotating in the other
direction.
Quadrature encoders (also referred to as incremental
encoders or optical encoders) are used in position and
speed detection of rotating motion systems.
Quadrature encoders enable closed-loop control of
many motor control applications, such as Switched
Reluctance (SR) Motor and AC Induction Motor
(ACIM).
The QEI module (Figure 8-3) includes:
• Three input pins for two phase signals and index
pulse
• Programmable digital noise filters on inputs
• Quadrature decoder providing counter pulses and
count direction
• 16-bit up/down position counter
• Count direction status
• x2 and x4 count resolution
• Two modes of Position Counter Reset
• General Purpose16-Bit Timer/Counter mode
• Interrupts generated by QEI or counter events
Typically, three outputs termed, Phase A, Phase B and
INDEX, provide information that can be decoded to
provide information on the movement of the motor
shaft, including distance and direction.
A quadrature decoder captures the phase signals and
index pulse and converts the information into a numeric
count of the position pulses. Generally, the count will

Input Capture Module
The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The dsPIC33F devices support up to eight input
capture channels.
The input capture module captures the 16-bit value of
the selected time base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:
1.
2.
3.
Simple Capture Event modes
- Capture timer value on every falling edge of
input at ICx pin
- Capture timer value on every rising edge of
input at ICx pin
Capture timer value on every edge (rising and
falling)
Prescaler Capture Event modes
- Capture timer value on every 4th rising
edge of input at ICx pin
- Capture timer value on every 16th rising
edge of input at ICx pin
Each input capture channel can select between one of
two 16-bit timers (Timer2 or Timer3) for the time base.
The selected timer can use either an internal or an
external clock.
Other operational features include:
The dsPIC33F device may have up to eight output
compare channels, designated OC1 through OC8.
Refer to the specific device data sheet for the number
of channels available in a particular device. All output
compare channels are functionally identical.
Each output compare channel can use one of two
selectable time bases. The time base is selected using
the OCTSEL bit (OCxCON<3>). An ‘x’ in the pin,
register or bit name denotes the specific output
compare channel. Refer to the device data sheet for the
specific timers that can be used with each output
compare channel number.
Each output compare module has the following modes
of operation:
• Single Compare Match mode
• Dual Compare Match mode generating
- Single Output Pulse
- Continuous Output Pulses
• Simple Pulse-Width Modulation mode
- With Fault Protection Input
- Without Fault Protection Input
Output compare channels, OC1 and OC2, support
DMA data transfers.

Data Converter Interface Module
The dsPIC33F Data Converter Interface (DCI) module
allows simple interfacing to devices such as audio
coder/decoders (codecs), A/D Converters and D/A
Converters.
• Device wake-up from capture pin during CPU
Sleep and Idle modes
• Interrupt on input capture event
• 4-word FIFO buffer for capture values
- Interrupt optionally generated after 1, 2, 3 or
4 buffer locations are filled
• Input capture can also be used to provide
additional sources of external interrupts.
The following interfaces are supported:
• Framed Synchronous Serial Transfer (Single or
Multi-Channel)
• Inter-IC Sound (I2S) Interface
• AC-Link (AC’97) Compliant mode
Input capture channels IC1 and IC2 support DMA data
transfers.
The output compare module features are quite useful
in applications that require controlled timing pulses or
PWM modulated pulse streams.
Many codecs intended for use in audio applications
support sampling rates between 8 kHz and 48 kHz and
use one of the interface protocols listed above. The
DCI automatically handles the interface timing
associated with these codecs. No overhead from the
CPU is required until the requested amount of data has
been transmitted and/or received by the DCI. Up to four
data words can be transferred between CPU interrupts.
The output compare module has the ability to compare
the value of a selected time base with the value of one
or two compare registers (depending on the operation
mode selected). Furthermore, it has the ability to
generate a single output pulse, or a repetitive
sequence of output pulses, on a compare match event.
Like most dsPIC33F peripherals, it also has the ability
to generate interrupts on compare match events.
The data word length for the DCI is programmable up
to 16 bits to match the data size of the dsPIC33F CPU.
However, many codecs have data word sizes greater
than 16 bits. Long data word lengths can be supported
by the DCI. The DCI is configured to transmit/receive
the long word in multiple 16-bit time slots. This
operation is transparent to the user and the long data
word is stored in consecutive register locations.

SPI™ Module
The Serial Peripheral Interface (SPI) module is a
synchronous serial interface for communicating with
other peripheral or microcontroller devices such as
serial EEPROMs, shift registers, display drivers, A/D
Converters, etc. It is compatible with Motorola® SPI and
SIOP interfaces.
This SPI module includes all SPI modes. A Frame
Synchronization mode is also included for support of
voice band codecs.
A series of 8 or 16 clock pulses (depending on mode)
shift out the 8 or 16 bits (depending on whether a byte
or word is being transferred) and simultaneously shift in
8 or 16 bits of data from the SDI pin. An interrupt is
generated when the transfer is complete.
Slave select synchronization allows selective enabling
of SPI slave devices, which is particularly useful when
a single master is connected to multiple slaves.
The SPI1 and SPI2 modules support DMA data
transfers.
Four pins make up the serial interface: SDI, Serial Data
Input; SDO, Serial Data Output; SCK, Shift Clock Input
or Output; SS, Active-Low Slave Select, which also
serves as the FSYNC (Frame Synchronization Pulse).
A device set up as an SPI master provides the serial
communication clock signal on its SCK pin.

for communicating with other peripheral or
microcontroller devices. These peripheral devices may
be serial EEPROMs, shift registers, display drivers, A/D
Converters, etc.
The Inter-Integrated Circuit (I2C) module offers full
hardware support for both slave and multi-master

8.11
Controller Area Network (CAN)
Module
The Controller Area Network (CAN) module is a serial
interface useful for communicating with other CAN
modules or microcontroller devices. This interface/
protocol was designed to allow communications within
noisy environments.
The CAN module is a communication controller
implementing the CAN 2.0 A/B protocol, as defined in
the BOSCH specification. The module supports
CAN 1.2, CAN 2.0A, CAN2.0B Passive and CAN 2.0B
Active versions of the protocol. Details of these protocols
can be found in the BOSCH CAN specification.
The CAN module features:
• Implementation of the CAN protocol CAN 1.2,
CAN 2.0A and CAN 2.0B
• Standard and extended data frames
• Data lengths of 0-8 bytes
• Programmable bit rate up to 1 Mbit/sec
• Automatic response to remote frames
• Up to 16 receive buffers in DMA RAM
• FIFO Buffer mode (up to 64 messages deep)
• 16 full (standard/extended identifier) acceptance
filters
• 3 full acceptance filter masks
• Up to 8 transmit buffers in DMA RAM
• DMA can be used for transmission and reception
• Programmable wake-up functionality with
integrated low-pass filter
• Programmable Loopback mode supports self-test
operation
• Signaling via interrupt capabilities for all CAN
receiver and transmitter error states
• Programmable clock source
• Programmable link to timer module for
time-stamping and network synchronization
• Low-power Sleep and Idle mode
The CAN bus module consists of a protocol engine and
message buffering/control. The CAN protocol engine
handles all functions for receiving and transmitting
messages on the CAN bus. Messages are transmitted
by first loading the appropriate data registers. Status
and errors can be checked by reading the appropriate
registers. Any message detected on the CAN bus is
checked for errors and then matched against filters to
see if it should be received and stored in one of the
receive registers.

I/O Pins
The I/O pins have the following features:
Some pins for the I/O pin functions are multiplexed with
an alternate function for the peripheral features on the
device. In general, when a peripheral is enabled, that
pin may not be used as a general purpose I/O pin.
All I/O port pins have three registers directly associated
with the operation of the port pin. The Data Direction
register determines whether the pin is an input or an
output. The Port Data Latch register provides latched
output data for the I/O pins. The Port register provides
visibility of the logic state of the I/O pins. Reading the
Port register provides the I/O pin logic state, while
writes to the Port register write the data to the Port Data
Latch register.
I/O port pins have latch bits (Port Data Latch register).
This register, when read, yields the contents of the I/O
latch and when written, modifies the contents of the I/O
latch, thus modifying the value driven out on a pin if the
corresponding Data Direction register bit is configured
for output. This can be used in read-modify-write
instructions that allow the user to modify the contents
of the Port Data Latch register, regardless of the status
of the corresponding pins.
© 2005 Microchip Technology Inc.
• Schmitt Trigger input
• CMOS output drivers
• Weak internal pull-up
All I/O pins configured as digital inputs can accept 5V
signals. This provides a degree of compatibility with
external signals of different voltage levels. However, all
digital outputs and analog pins can only generate
voltage levels up to 3.6V.
The input change notification module gives dsPIC33F
devices the ability to generate interrupt requests to the
processor in response to a change of state on selected
input pins. This module is capable of detecting input
changes of state, even in Sleep mode, when the clocks
are disabled. There are up to 24 external signals (CN0
through CN23) that can be selected (enabled) for
generating an interrupt request on a change of state.
Each of the CN pins also has an optional weak pull-up
feature.

dsPIC33F INSTRUCTION SET
9.2.1
9.1
Introduction
As the instruction summary tables show, most
instructions execute in a single cycle with the following
exceptions:
The dsPIC33F instruction set provides a broad suite of
instructions which supports traditional microcontroller
applications, and a class of instructions which supports
math-intensive applications. Since almost all of the
functionality of the PICmicro® MCU instruction set has
been maintained, this hybrid instruction set allows a
friendly DSP migration path for users already familiar
with the PICmicro microcontroller.
9.2
Instruction Set Overview
The dsPIC33F instruction set contains 84 instructions
which can be grouped into the ten functional categories
shown in Table 9-1. Table 9-2 defines the symbols
used in the instruction summary tables, Table 9-3
through Table 9-12. These tables define the syntax,
description, storage and execution requirements
for each instruction. Storage requirements are represented in 24-bit instruction words and execution
requirements are represented in instruction cycles.
Most instructions have several different addressing
modes and execution flows which require different
instruction variants. For instance, there are six unique
ADD instructions and each instruction variant has its
own instruction encoding.

MULTI-CYCLE INSTRUCTIONS
• Instructions DO, MOV.D, POP.D, PUSH.D,
TBLRDH, TBLRDL, TBLWTH and TBLWTL
require 2 cycles to execute.
• Instructions DIVF, DIV.S, DIV.U are singlecycle instructions, which should be executed
18 consecutive times as the target REPEAT
instruction.
• Instructions that change the program counter also
require 2 cycles to execute, with the extra cycle
executed as a NOP. Skip instructions, which skip
over a 2-word instruction, require 3 instruction
cycles to execute with 2 cycles executed as a
NOP.
• The RETFIE, RETLW and RETURN are special
cases of instructions that change the program
counter. These execute in 3 cycles unless an
exception is pending, and then they execute in
2 cycles.
Note:
9.2.2
Instructions that access program memory
as data, using Program Space Visibility,
incur some cycle count overhead.
MULTI-WORD INSTRUCTIONS
As the instruction summary tables show, almost all
instructions consume one instruction word (24 bits),
with the exception of the CALL, DO and GOTO
instructions, which are flow instructions listed in
Table 9-9. These instructions require two words of
memory because their opcodes embed large literal
operands.

MPLAB SIM Software Simulator
The MPLAB SIM software simulator provides code
development for the dsPIC33F family in a PC-hosted
environment by simulating the dsPIC33F device on an
instruction level. On any instruction, you can examine
or modify the data areas and apply stimuli to any of the
pins from a file or by pressing a user-defined key.
The execution can be performed in Single-Step,
Execute-Until-Break or Trace mode. The MPLAB SIM
software simulator fully supports symbolic debugging
using the MPLAB C30 C compiler and assembler. The
software simulator gives you the flexibility to develop
and debug code outside of the laboratory environment,
making it an excellent multi-project software
development tool. Complex stimuli can be injected from
files, synchronous clocks or user-defined keys. Output
files log register activity for sophisticated post analysis.
Besides modeling the behavior of the CPU, MPLAB
SIM also supports the following peripherals:
• Timers
• Motor Control PWM
• Input Capture
• UART
• 12-Bit ADC
• I/O Ports
• 10-Bit ADC

Noise Suppression Library
11.10 Acoustic Echo Cancellation Library
The dsPIC DSC Noise Suppression Library provides a
function to suppress the effect of noise interfering with
a speech signal. This function is useful for microphonebased applications which have a potential for incoming
speech getting corrupted by ambient noise captured by
a microphone. It is especially suitable for systems in
which an acoustically isolated noise reference is not
available, such as:
The Acoustic Echo Cancellation (AEC) Library
provides a function to eliminate echo generated in the
acoustic path between a speaker and a microphone.
This function is useful for speech and telephony
applications in which a speaker and a microphone are
located in close proximity to each other and therefore,
susceptible to signals propagating from the speaker to
the microphone resulting in a perceptible and
distracting echo effect at the far end. It is especially

interference from signals received over a
communication channel
The Noise Suppression Library uses an 8 kHz sampling
rate. However, the library includes sample rate
conversion functions that ensure interoperability with
libraries and speech sampling peripherals configured for
higher sampling rates (9.6 kHz, 11.025 kHz or 12 kHz).

Plug-in Modules
13.4
The various dsPIC33F development boards may use
the plug-in modules for the dsPIC33F silicon devices.
Since the boards contain device header pins on the
PCB, they also are used to provide flexibility for the
replacement of the dsPIC33F silicon. Three different
plug-in sample types will be provided, supporting the
64-pin, 80-pin and 100-pin TQFP package types for
General Purpose and Motor Control Family device
samples. The use of plug-in samples is considered to
be an interim development board mechanization.

Table B-1 provides a brief description of device I/O
pinouts and the functions that may be multiplexed to a
port pin. Multiple functions may exist on one port pin.
When multiplexing occurs, the peripheral module’s
functional requirements may force an override of the
data direction of the port pin.
