1-1-1 Introduction
The MN102 series linear addressing version designs the new architecture for Clanguage programming based on a detailed analysis for embedded applications.
This improves the system architecture in speed and function to meet the requirements in user systems including miniaturization and low power consumption.
The MN102LF61G series contains sufficient peripheral equipments, four CS signals and a memory interface that supports burst ROM, and realize high-efficiency
real-time control in variety of systems such as printer, electric musical instruments, audiovisual equipments, home electric appliances, cars, robots and computer peripherals.
The MN102L series adapts a load/store architecture method for computing within
registers and a harvard architecture method for separating instructions bus and
operand bus. Using one byte/one machine cycle basic instructions minimizes
code size and improves compiler efficiency.

1-1-2 Features
The MN102L series contains a flexible and optimized hardware architecture as
well as a simple and efficient instruction set. It obtains economical efficiency and
high speed.
1. Linear Addressing for Large Systems
The MN102L series contains up to 16 Mbytes of linear address space. The CPU
provides an effective development environment without detecting borders between address spaces. The hardware architecture is also optimized for large
systems. The memory is not divided into instruction space and data space so
that operations can share instructions.
I-2
Overview
Chapter 1 Overview
2. Single-byte Basic Instruction Length
The MN102L series has replaced general registers with eight internal
CPU registers divided four address registers (A0 to A3) and four data
registers (D0 to D3). The register specification fields are four bits or
less, and the code sizes of the frequently used basic instructions including register- to-register operations and load/store operations are
one byte.

3. High-speed Pipeline Processing
The MN102L series executes instructions in a 3-stage pipeline: fetch,
decode and execute. This allows the MN102 series to execute instructions of single byte in one machine cycle (100 ns at 20 MHz).

4. Simple Instruction Set
The MN102L series uses an instruction set of 36 instructions, designed specially
for the programming model for embedded applications. To compress the code
size, instructions have a variable length of one byte to five bytes. The most frequently used instructions in C-language compiler are single byte.
5. High-speed Interrupt Response
The MN102L series can respond quickly to interrupt handling even during the execution of the instruction with long execution cycles by suspending it. After an interrupt occurs, the program moves to the interrupt
handler within 11 cycles or less. The MN102 series enhances real-time
control performance using the interrupt handler which adjusts interrupt
handling speed depending on user requirements.

6. Flexible Interrupt Control Structure
The interrupt controller is divided into eight groups (Group 0 is reserved for NMI.)
and supports a maximum of four vectors for each group in total of 26 vectors.
Each group can be set to one of seven priority levels. This provides the software
design flexibility and accurate control. The CPU is compatible with software from
previous Panasonic peripheral modules.
7. HIgh-speed, high-functionality external interface
The MN102L series provides DMA, handshaking, bus arbitration, and other functions that ensure a fast, efficient interface with other devices.
8. C-Language Development Environment
The MN102L series contains highly efficient C compiler and simple hardware
optimized for C-language programming. With this advantage, this series improves
development environment for C-language embedded applications without expanding the program size. The PanaXSeries development tools support the MN102
series devices.
9. Outstanding Power Savings
The MN102L series contains separate buses which distribute and reduce load
capacitance. This greatly reduces overall power consumption compared to our
conventional models. The MN102L series also supports three modes of SLOW,
HALT and STOP for power savings.

Functions
Clock Generator
The clock generator contains the clock oscillation circuit connected to an external
crystal and supplies the clock to all CPU blocks. (It has a built-in 4x-speed circuit.)
Program Counter
The program counter generates addresses for instruction queues. Normally, it
gets increments based on the sequencer indication, but for branch instructions
and interrupt acceptance, it sets the branch address or ALU operation results.
Instruction Queue
The instruction queue saves up to 4 bytes of prefetched instructions.
Instruction Decoder
The instruction decoder decodes the instruction queue content, generates control signals needed for the instruction execution, and executes the instruction by
controlling each block in the CPU.
Instruction Execution
Controller
The instruction execution controller controls the operations of each CPU function
based on results from the instruction decoder and interrupt requests.
ALU
The ALU calculates the operand addresses for arithmetic operations, logic operations, shift operations, register relative indirect, indexed addressing and register
indirect addressing mode.
Internal ROM, Internal RAM
Internal ROM and internal RAM are allocated as the execution program, data and
stack areas.
Address Registers
(An)
The address registers (An) store the addresses of memory accessed during data
transfer. They also store the base addresses in the register relative indirect,
indexed addressing and register indirect addressing mode.
Operation Registers
(Dn, MDR)
The data registers (Dn) store the operation results and transfer the data to memory.
They also store the offset addresses in indexed addressing and register indirect
addressing mode.
The multiplication/division register (MDR) stores the data for multiplication/division operations.
PSW
The processor status word (PSW) stores the flags that indicate the status of the
CPU interrupt controller and operation results.
Interrupt Controller
The interrupt controller detects the interrupt requests from the peripheral functions, and requests the CPU to move to the interrupt handling.
Bus Controller
The bus controller controls the connection between the CPU internal bus and the
CPU external bus. It also contains the bus arbitration function.
Internal Peripheral Function
This series contains the peripheral functions including timers, serial interface,
A/D converter and so on.

2-1-1 Overview
The MN102L610B has only processor mode.
This series contains three memory modes of single-chip mode,
memory expansion mode and processor mode. The chip of this
series connects to the external memory or I/O consisted of gate
array in the expansion mode or processor mode. The address space
is divided into four fixed areas (Block 0 to Block 3). Each block has
approximately 4 MB area and generates four chip-select signals to
its corresponding external space. (The address space is optionally
divided when the chip-select signals are generated externally.)
16-bit bus width or 8-bit bus width is selected for each block. The WORD pin sets
the 16-bit bus width or 8-bit bus width for Block 0 where the reset handler exists.
On the other hand, the MEMMDn register sets the bus width for Block 1 to Block
3. See 1-4 Pin Functions for pin setting.

In this series, the addresses of x’000000’ to x’007FFF’ replaces the addresses of
x’800000’ to x’807FFF’. Beacuse of this, the CS2 signal is generated even though
the program accesses the address of x’000000’ to x’007FFF’ shown in Figure 21-1. The CS1 pin, CS2 pin and CS3 pin are allocated into Block1, Block2 and
Block 3 respectively, and these pins become low level.

The MEMCTR register and the MEMMDn register need to set the conditions
matched the system configuration during the initialization program. [See “9-4
Initialization Program“]
The MEMCTR register sets x’04n0’ (n = 0 to 3, the wait cycle of
special registers is normally 1) during the initialization program.
The MEMMD0 register sets the wait cycle for the device connected to Block 0.
The bits for selecting bus mode do noe exist in the MEMMD0 register like other
MEMMDn registers because the bus width for Block 0 is selected using the pin.
Setting the WAIT[1:0] is ignored in the burst ROM support area when using burst
ROM.

2-1-3 ROM Burst Mode Timing
This LSI series supports interface for ROM corresponding to burst
mode accesses. The burst mode is a mode which reads the data of
consecutive few bytes (only few lower bits are changed) at highspeed (access twice faster than normal access).
Use burst mode only during the
address/data separated mode.
(Do not use burst mode during the
address/data shared mode.)
Access area for burst mode is
x’080000’ to x’0FFFFF’. The access cycle in x’080000’ to
x’0FFFFF’ is 1 wait cycle outside
the page and no wait cycle in the
page. (Bits[1:0] of the MEMMD0
register are ignored.)
This series supports the lower 2 bits (4 bytes for page size), the lower 3 bits (8
bytes for page size), and the lower 4 bits (16 bytes for page size).

Chapter 2 Bus Interface
This series has the access cycle with penalty and without penalty when the chip
accesses to devices except ROM after it accesses to ROM during the burst mode.
Figure 2-1-9 shows their timings and Figure 2-1-10 shows the connection example.
The ROM burst mode is used only during the address/data separated mode and
the WAIT pin is ignored even though handshake mode us selected. (Figure 2-19 shows the timing of 8 bytes/page during the 16-bit bus mode.)

Figure 2-1-10 Access Timing Memory Connection Example
During ROM Burst Mode
As Figure 2-1-10 shows, the access is fast but RE signal (BSTRE) for burst ROM
is required when access without penalty cycle is selected. In addition, the external 3-state buffer (for example, 74ALS541) may be required when the ROM data
hold time is long.

Control Register
Interrupt Groups
Chapter 3 Interrupts
The control registers are assigned to each corresponding interrupt group except
Group 0 and control the assigned interrupt vectors. For example, in the MN102LF
53G, when timer 0 becomes underflow, the interrupt request flag (IRF1=TM0IR)
of the maskable interrupt control register 1 (G1ICR) becomes 1. At this point, an
interrupt request is output to the CPU core if the corresponding interrupt enable
flag (IEN1=TM0IE) is 1. Comparing the interrupt mask level (IM2 to 0 ) of the
processor status word (PSW) with the group interrupt level (ILVn=G1LV[2:0]) of
the G1ICR register and the interrupt enable flag (IE) of PSW determine whether
the CPU core receives the interrupt or not.

3-3 Interrupt Setup Examples
3-3-1 External Pin Interrupt Setup
An interrupt occurs on the negative (falling) edge from the external
interrupt pin IRQ0 (PA0).
The external interrupt edge specification register (EXTMD) is set to the interrupt
request generation at low level after reset release, and the IRQ0IR bit of the
maskable interrupt control register 1 (G1ICR) becomes 0.
„ Interrupt Enable Setup
(1) Set the interrupt conditions of the interrupt pin IRQ0 (PA0). In this case, set
the IRQ0TG of the EXTMD register to 2 (bit string 10:negative edge).

Interrupt Setup Examples
Chapter 3 Interrupts
Thereafter, an interrupt occurs when the negative (falling) edge is generated on
the interrupt pin IRQ0 (PA0). The program branches to x’080008’ when the interrupt is accepted.
„ Interrupt Handling
(4) Specify the interrupt group by reading the interrupt accept group register
(IAGR) during interrupt prehandling.
(5) Specify the interrupt vector in the group by reading the G1ICR register.
Check the IRQ0ID with the bit test instruction (BTST). If IRQ0ID is 1,
execute the interrupt handling.
(6) Clear the IRQ0IR bit of the G1ICR register.
(7) Return to the main program with the interrupt return instruction (RTI) after
the interrupt handling ends.
Normally, the program generates
the interrupt start address and
branches to that address.
During interrupt service routine,
the IM and IE of PSW become the
interrupt level and 0 respectively.
The multiple interrupts are not allowed. It means that other interrupts except the non-maskable interrupt are not accepted during interrupt service routine unless the
PSW is set.

Chapter 3 Interrupts
3-3-2 Watchdog Timer Interrupt
An interrupt occurs by using the watchdog timer.
When the watchdog fanction is used, operation is started by setting the WDRST
flag of the CPU mode control register (CPUM) to enable (‘0’) after reset. The
watchdog timer needs to be cleared during the main program because a nonmaskable interrupt occurs when the watchdog counter overflows.
„ Interrupt Enable Setup
When the watchdog timer counts
65536 cycles of SYSCLK (6.5536
ms with a 20 MHz oscillator), a
watchdog interrupt occurs.
(1) Enable interrupts by setting the interrupt enable flag (IE) of the processor
status Word (PSW) to 1 and the interrupt mask level (IMn) to 7 (bit string
111).
(2) Clear the WDRST flag of the CPUM register. This starts the watchdog
timer.

„ Watchdog Timer Clear
Normally, clear the watchdog
timer before an interrupt occurs.
Normally, the program generates
the interrupt start address and
branches to that address.
The IM of PSW becomes the highest level during interrupt handling
and other interrupts are not accepted.
III-62
Interrupt Setup Examples
(3) Set the WDRST flag of the CPUM register to 1 and then immediately clear
to 0. The watchdog timer is cleared to 0 when the WDRST flag is 1.
„ Interrupt Handling
The program branches to x’080008’ when an interrupt is generated and accepted.
(4) Specify the interrupt group by reading the interrupt accept group register
(IAGR) during interrupt prehandling.
(5) Verify a watchdog interrupt by reading the nonmaskable interrupt control
register (G0ICR). Check the WDIF with the bit test instruction (BTST). If
WDIF is 1, execute the interrupt service routine.
Chapter 3 Interrupts
(6) Clear the WDIF flag of the G0ICR register.
(7) Return to the main program with the interrupt return instruction (RTI) after
the interrupt handling ends.
The watchdog timer and the oscillation stabilization wait counter are shared. The
watchdog timer operates as the oscillation stabilization wait counter when the
CPU returns from the STOP mode. Because of this, the WDIF flag is cleared to
0 when the CPU moves to the STOP mode. The WDIF flag is cleared to 0 again
after the CPU moves to the normal mode. [

Timer 1 to timer 5 can cascade.
For example, cascading timer 1
and timer 2 can form as a 16-bit
timer. cascading timer 3, timer 4
and timer 5 can form as a 24-bit
timer. Cascading these timers can
form a 40-bit timer at most.
An underflow interrupt occurs only
when these timers are down
counting.
IV-72
Timers
Timer 0 to Timer 5
Timer 0 to Timer 5 are 8-bit timers. They are down counting and are divided by
the 8-bit value set in the base register (TMnBR) plus one. (Do not set 0 to TMnBR).
An interrupt occurs when each timer underflows (the binary counter changes
from xÕ00Õ to the 8-bit value). They can function as interval timers, event
counters, clock output, base clock for serial interface and A/D conversion start
timing.
Timer 6 and Timer 7
Timer 6 and Timer 7 are 16-bit timers. They are up/down counting. Each timer
has two compare/capture registers (TMnCA and TMnCB). These registers capture and compare the up/down counter value, generate PWM and interrupts. The
PWM contains the double buffer mode that changes the cycle and transition from
the next cycle. This prevents the PWM waveform losses and distorts during
timing changes. These timers can function as interval timers, event counters (at
clock oscillation), one-phase PWM, two-phase PWM, two capture input, dual
two-phase encoders, one-shot pulse generators and external count direction controllers.

Each timer n (n=2 to 5) cascade inputs cascade output of timer n-1. Therefore,
timer does not function as a 8-bit counter but it functions as a 16-bit counter.
SYSCLK is a signal of dividing the clock from OSCI pin by 2 (10 MHz with a 20MHz oscillator) during normal mode or HALT0 mode. SYSCLK becomes a signal of dividing the clock from XI pin by 2 (16 kHz with a 32 kHz oscillator) during
SLOW mode or HALT1 mode. SYSCLK stops during STOP0 mode or STOP1
mode. SYSCLK outputs to the external SYSCLK pin. The fxi/4 means a signal of
dividing the clock from XI pin by 4 (18 kHz with a 32 kHz oscillator) during modes
except STOP0 and STOP1 modes. The fxi/4 stops during STOP0 or STOP1
mode.

4-2-1 Event Counter Using 8-bit Timer
The event counter setup procedures for Timer 0 to Timer 5 are the
same. In this example, timer 2 counts the rising edge of the TM2IO
pin input four times and generates an interrupt at underflow.
(1) Set the interrupt enable flag (IE) of the processor status word (PSW) to 1.
This verification is unnecessary
immediately after a reset.
(2) Verify that counting is stopped using the timer 2 mode register (TM2MD).

(6) Set both TM2LD and TM2EN of the TM2MD register to 0. If this setting is
omitted, the timer 2 binary counter may not start at the first cycle.
Changing the clock source while
controlling count operation will
corrupt the binary counter value.
(7) Set both TM2LD and TM2EN to 0. This starts timer 2. Counting starts at

(6) Set both TM0LD and TM0EN of the TM0MD register to 0. If this setting is
omitted, the timer 0 binary counter may not start at the first cycle.
If selecting 1 of divisor, set 0 to
the timer 0 base register (TM0BR)
once again after step (7). The first
count is the value set in step (4),
but the second count becomes 1.
For example, if 0 is set to TM0BR
in step (4), the first count is 257
and the second count becomes 1.
(7) Set TM0LD and TM0EN to 0 and 1 respectively. This starts timer 0. Counting starts at the beginning of the next cycle. When the timer 0 binary

4-3-1 Event Counter Using 16-bit Timer
The event counter setup procedures for Timer 6 and Timer 7 are
same except the up/down counting selection. In this example, timer
6 counts TM6IOB pin input (SYSCLK/2 or less, 5 MHz or less with a
20-MHz oscillaor) and generates an interrupt on the second cycle
and fifth cycle.
Use the MOV instruction to set the
data and always use 16-bit write
operations.
Stop TM6BC counting and initialize (clear) TM6BC and RS.F.F.
„ Interrupt Enable Setup
(1) Enable interrupts. At the same time, clear all prior interrupt requests. Set
G6LV[2:0] bits of the G6ICR to the interrupt level of 6 to 0, TM6AIR and
TM6BIR to 0, and TM6AIE and TM6BIE to 1. For example, write xÕ4600Õ
to the G6ICR register. Thereafter, an interrupt occurs when the timer 6
capture A and the timer 6 capture B occur.
„ Timer 6 Setup
(2) Set the operating mode to the timer 6 mode register (TM6MD). Verify that
counting is stopped and an interrupt is disabled. Select up counting or
down counting. Select TM6IOB as the timer 6 clock source.

When timer n changes the duty of PWM output waveforms dynamically, the PWM
output waveforms and interrupts may corrupt at the timing of changing the TMnCB
value in the single buffer mode. In the double buffer mode, the corrupt of PWM
output waveforms and interrupts does not occur at any timing of changing the
TMnCB value. This corruption does not occur even when the output waveforms
consist of 1 and 0.

4-3-4 One-phase Capture Input Using 16-bit Timer
The one-phase capture input setup procedures for timer 6 and timer
7 are same except the up/down counting selection. In this example,
timer 7 divides SYSCLK by 65536 and measures how long the
TM7IOA input is high. An interrupt occurs on the capture B and the
width where the TM7IOA input is high is calculated by the instruction
(TMnCB - TMnCA).
Use the MOV instruction to set the
data and always use 16-bit write
operations.
Stop TM7BC counting and initialize (clear) TM7BC and RS.F.F.
„ Interrupt Enable Setup
(1) Enable interrupts. At the same time, clear all prior interrupt requests. Set
G7LV[2:0] bits of the G7ICR to the interrupt level of 6 to 0, TM7BIR 7 and
TM7BIE to 0 and 1 respectively. For example, write x’4400’ to the G7ICR
register. Thereafter, an interrupt occurs when the timer 7 capture B occurs.
„ Timer 7 Setup
(2) Set the operating mode to the timer 7 mode register (TM7MD). Verify that
counting is stopped and an interrupt is disabled. Select up counting or
down counting. Set TM7LP to 0 to count the loop of 0 to x’FFFF’. Select
SYSCLK as the timer 7 clock source.

(6) Execute interrupt processing. The interrupt processing specifies the interrupt group and vector, and clears IRFn.
(7) Calculate the width. Store the TM7CA value and TM7CB value to the data
register and subtract TM7CA from TM7CB. Ignore C and V flags. The

Figure 4-3-9 shows the one-shot pulse output timing. Set TM7EN on the falling

TM7BC is 0, the initial value of TM7IOA is 0, and a reset (R) signal and a set (S)
signal cannot be output. When counting starts, TM7BC changes from 0 to 1 and
the S signal is output. TM7IOA becomes 1 and the pulse is output. TM7BC
reaches 3, TM7BC resets and changes from 3 to 0. At the same time, the R
signal is output and TM7IOA outputs 0. Because TM7ONE is set to 1, the TM7EN
flag is also reset and counting stops. When TM7IOB rises again, TM7EN is set
and the same operation is repeated. As a result, the one-shot pulse is output.

5-1-1 Overview
This LSI series contains two serial interfaces. Each serial interface
transmits and receives the data in the synchronous mode, asynchronous mode and I2C mode. The maximum baud speed in synchronous mode is SYSCLK/4. The maximum baud speed in asynchronous mode is 312,500 bps with a 20-MHz oscillator. (The baud
speed can be set to 312,500 bps or more by changing the oscillation
frequency.)

5-1-2 Control Registers
Three registers control the serial interface: serial control register
(SCnCTR), serial transmit/receive register (SCnTRB) and serial status register (SCnSTR).

Serial 1 Status Register
(SC1STR), x'00FD93'
The serial control register (SCnCTR) sets the operating conditions for serial interface. This register controls clock source selection, parity bit selection, protocol
selection and transmit/receive enable.
The transmit data is written to the serial transmit/receive register (SCnTRB), while
the receive data is written to the SCnTRB register. The transmission starts at the
end of the first cycle or second cycle of the transfer clock (timer 2 underflow or
timer 3 udnerflow) after the data is written to SCnTRB. The serial transmission is
operated in double buffer mode. After the reception is completed, the data is set
to the SCnTRB register. The receive data is loaded when an interrupt occurs or
the SCnRXA flag of the SCnSTR register is 1.
The serial status register (SCnSTR) reads the status of error detection of serial
interface. An overrun error occurs when the next data is received before the
received data is loaded by SCnTRB. An error does not occur on the next cycle by
reading the SCnTRB register. The overrun error data is updated when the last bit
(the 7th bit or the 8th bit) of the data is received. A parity error occurs when the
parity bit is 1 although it is supposed to 0, when the parity bit is 0 although it is
supposed to 1, when the parity bit is odd although it is even and when the parity
bit is even although it is supposed to set odd. The parity error data is updated
when the parity bit is received. A framing error occurs when the stop bit is 0. The
framing error data is updated when the stop bit is received. Figure 5-1-2 shows
the timing when each bit of the serial status register (SCnSTR).
Igonore MSB (bit 7) in the 7-bit
transmission.
Write the data to the serial transmit/receive register after verifying
the data is not in transmission by
checking the SCnTBSY of the
SCnSTR register or a transmission end interrupt. The serial
transmission may not occur if writing to the serial transmit/receive
register during the transmission is
operated.
The MSB (bit 7) becomes 0 in the
7-bit reception.

The serial interface can connect to the devices which can slave transmit and
receive. The SBO pin and SBT pin connect pull-up resistors (externally or internally).
Master
Transmition/Reception
The I2C mode is used only as the
master transmission/reception in
the single master system. Because I2C mode do not control the
protocol, setting the transfer baud
rate and controlling the transfer
start are required to function the
slave transmission/reception.

The acknowledge (ACK) bit is substituted for a parity bit. In the system requiring
the ACK, fix the parity bit to 1 (SCnPTY[2:0] = 101) when this LSI master transmits the data. In that case, a parity error occurs when the ACK (low level) returns
from the slave. Therefore, the parity bit of the SCnSTR register becomes 1 when
the transmission is completed normally.
On the other hand, when this LSI master receives the data, fix the parity bit to 0
(SCnPTY[2:0] = 100) if the ACK returns from the slave and set the parity bit to 1
(SCnPTY[2:0] = 101) if the ACK does not return.
During I2C transmission/reception, the transmit state flag of the SCnSTR register
shows the transmission/reception in progress.
„ Asynchronous Serial Transfer Speed
In asynchronous mode, set the serial transfer clock to 16 times of transfer baud
rate. The following is the baud rate calculation.
Baud Rate (bps) = OSCI, OSCO x 1/32 x 1/timer divisor
The transmission is possible if the baud rate error is within 2 %. Table 5-1-3 to
Table 5-1-10 show the baud rates with frequently used oscillators.

x 20 MHz oscillation
x Baud Rate = 9600 bps (SYSCLK/65 by timer 2)
x Bit Order: LSB
x 8-bit data transfer
x Two stop bits
x Odd parity
The next data is transmitted when a transmission end interrupt occurs.

The transmission starts when the data is written to the SC0TRB register. The
transmission starts synchronizing with timer 2 underflow. An interrupt occurs
after the transmission is completed and the new data is written to the SC0TRB
register during the interrupt service routine. The SC0TBSY flag of the SC0STR
register polls if an interrupt does not occur.
Setting timer is required during serial reception in asynchronous
mode.
The serial interface generates the serial transfer baud rate with timer 2 or timer 3
divided by 16. With a 20-MHz oscillator (SYSCLK is 10 MHz) and 9600 bps, 10
MHz/16/9600 = 65.10
Therefore, set the timer 2 or timer 3 underflow to 65.
„ Pin Setup
Set P72 pin to data output of serial interface 0. [See Chapter 8 Ports]

(4) Set both TM2LD and TM2EN to 0.
Do not change the clock source
once you have selected it. Changing the clock source while controlling count operation will corrupt
the binary counter value.
(5) Set TM2LD and TM2EN to 0 and 1 respectively. This starts timer 2.
If this step is omitted, TM2BC may
not count during the first cycle.
(3) Load the TM2BR value to TM2BC. To do this, set TM2LD and TM2EN to 1
and 0 respectively. At the same time, select the clock source.
„ Serial Interface 0 Setup
(6) Enable interrupts. At this point, clear all prior interrupt requests. Set the
G3ICR register to the interrupt level (level 6 to 0), SC0TIR and SC0TIE to
0 and 1 respectively. For example, write the G3ICR register to xÕ4400Õ.
Thereafter, a serial transmission end interrupt occurs when the data written to the serial transmit/receive register is transferred.

5-2-3 Serial Transmission/Reception in I2C Mode Using Timer 3
This section describes the example of serial interface 0 transmission/reception in I2C mode explaining I2C start sequence transmission, data transmission, data reception and I2C stop sequence transmission in order.
„ Pin Setup
Set P70 pin and P72 pin to serial clock input and port input respectively. If P70 pin
and P72 pin do not equip a pull-up resistor externally, set the pull-up resistor by
the pull-up control register. [See Chapter 8 Ports]
„ Serial Interface 0 Setup
<Initial Setup>
(1) Set the operating conditions to the serial 0 control register (SC0CTR). In
I2C mode, select open-drain, 8-bit data transfer, MSB as the bit order. In
the system with the response from slave (ACK), set parity bit to 1. (In the
system without ACK, select no parity.) Select timer 3 underflow/16 as the
clock source.

When selecting P70 and P72 to
I2C mode by the serial 0 control
register, these pins becomes output mode. Therefore, they should
be set to input when they are used
as ports.
In this example, select the slave
response.
Set both the transmission enable
flag and the reception enable flag
to 1.

(2) Set the I2C sequence output bit of the serial 0 control register (SC0CTR) to
1. This makes the SBO pin output low and generates the start sequence.

<Data Transmission>
(3) Load the data to the serial 0 transmit/receive register. This allows the data
to output. The SBO pin output changes with 1/8 cycles delay of the falling
edge of the SBT pin output.
After transmission, both SBO pin
output and SBT pin output stay
low.
Serial Interface Setup Examples
V-121
Chapter 5 Serial Interface
(4) After transmission ends, read the dummy data of the serial 0 transmit/
receive register (SC0TRB).
An interrupt (a serial 0 transmission end interrupt or a serial 0 reception end interrupt) or polling the
serial status register identifies the
transmission end.
(Polling the reception state flag
during I2C mode is prohibited.)
(5) Read the serial 0 status register and verify the parity error. If a parity error
occurs, the response is obtained from the slave correctly. If a parity error
does not occur, the response is not obtained from the slave. (This step is
not required in the system without ACK.)
When the data is transmitted continuously, repeat the steps (3) to (5).
<Data Reception>
(6) Load the dummy data x’FF’ to the serial 0 transmit/receive register
(SC0TRB). This allows the SBO pin to output resistive high (because the
SBO pin is an open-drain pin) and input low when the slave outputs low.
An interrupt (a serial 0 transmission end interrupt or a serial 0 reception end interrupt) or polling the
serial status register identifies the
reception end.
(7) After reception ends, retrieve the received data by reading the serial 0
transmit/receive register (SC0TRB).
(Polling the reception state flag
during I2C mode is prohibited.)
<Stop Sequence>
(8) Set the I2C sequence output bit of the serial 0 control register (SC0CTR) to
0. This makes the SBT pin output high and generates the stop sequence.
When the data is received continuously, repeat the steps (6) and (7).

„ Selecting the A/D Converter Clock Source
The A/D converter clock source is selected to SYSCLK, SYSCLK/2, SYSCLK/4
or SYSCLK/8 as the conversion time is 4.8 µs or more. Select the A/D converter
clock source as follows:
SYSCLK frequency/divisor ≤ 5 MHz
For example, select the A/D converter clock source as SYSCLK/4 (the conversion speed of 4.8 µs) or SYSCLK/8 (the conversion time of 9.6 µs) with a 20-MHz
oscillator. Select SYSCLK/2, SYSCLK/4 or SYSCLK/8 with a 10-MHz oscillator.
Select SYSCLK. SYSCLK/2, SYSCLK/4, SYSCLK/8 with a 5-MHz oscillator or
less. The conversion time is 12 cycles of the A/D converter clock source as
Figure 6-1-2 shows. For example, the conversion time is calculated as follows
when SYSCLK/4 is selected.

(3) Set the ANEN flag to ‘1’ to start the conversion. Conversion starts on the
falling edge of the A/D conversion clock source after ANEN is set to 1. The
conversion time is 12 cycles of the A/D conversion clock source (4.8 µs,
4.8 µs to 5.2 µs after ANEN is set).
(4) Wait for the conversion to end. Set the ANEN flag to 1 during the conversion and 0 after the conversion ends. The program waits until the ANEN
flag is cleared to 0.
(5) Read the A/D 2 conversion data buffer (AN2BUF). The converter divides 0
V to 5 V into 256 and the conversion result is the value from 0 to 255.
Set the ANEN flag to 1 when starting the conversion by software.
The CPU can read the conversion
result by generating an interrupt.
In this case, the CPU does not
need to wait until the ANEN flag
is set because an interrupt occurs
after the conversion result is

The ATC control register (ATCCTR) sets the transfer direction, the internal RAM
address for the ATC end and ATC enable. In addition, the ATC monitors the
overrun error (*) generation.
Overrun Error *
An overrun error occurs when a next serial 0 reception end interrupt occurs before the ATC operation is completed after the serial 0 reception end interrupt
occurred during the serial 0 reception (ATCDIR = ‘0’). When this error occurs,
setting bit 14 (OVREF) of the ATCCTR register to 1 as well as negating bit 15
(ATCEN) ends the ATC operation forcibly. At this point, the data stored in the
address which subtracted by 1 from the internal RAM address the ATCBC counter
shows is invalid. (No data is stored in the address the ATCBC counter shows.)
First, the ATC binary counter (ATCBC) sets the start address of internal RAM.
Next the ATCBC counter shows the RAM address to write (or read) during ATC
operation.
The internal RAM area where the ATC can transfer the data is 1 k
byte of x’008000’ to x’0083FF’. The upper 14 bits are fixed at
‘00000000111000’. Therefore, the lower 10 bits are read when
the ATCBC counter is read. The address in the ATCCTR register
or the ATCBC counter is set to only lower 10 bits.

7-2 ATC Setup Examples
7-2-1 Serial Reception
The ATC transfers the serial transmit/receive buffer contents to internal RAM automatically after the serial reception is completed. The
ATC generates an ATC transfer end interrupt after the ATC transfers
5 times, and starts software processing. The start address of the
ATC destination is x’00E0A0’.

8-1 Ports
8-1-1 Overview
This LSI series contains ten I/O ports. Of ports 0 to 5, port 8 and port
9 are 8 bits. Port 7 and port A are 6 bits. Port 6 is 4 bits. All ports are
bidirectional. Port 0 and Port 1 control the I/O direction in 8-bit unit.
Port 2 controls the I/O direction in 4-bit unit while ports 3 to A control
the I/O direction in bit unit.

Port 0 is used as the port 0 general-purpose port, data (address/data separated)
input/output, or address/data (address/data shared) input/output. At reset, this port
(AD07 to AD00)
operates as a general-purpose port input during other modes except processor
mode and as D07 to D00 (AD07 to AD00) pins during processor mode. However,
this port operates as a general-purpose port during processor mode when 8-bit bus
width is selected for all spaces in address/data separated mode. The mode for port
0 is selected in 8-bit unit. During processor mode (without 8-bit bus width setting for
all spaces), P0MD is invalid. During memory expansion mode, set P0MD and P0DIR
to 1 and 0 respectively.

The port output register (PnOUT) sets the data to be output. The port input
register (PnIN) reads the pin values. The port input/output control register (PnDIR)
sets the input or output of all bits or each bit. The output mode register (PnMD)
selects the port output. The port pull-up control register (PPLU) selects on/off of
each pin.
The pullup resistor is approximately 30 kΩ. See the product

1. Absolute Maximum Ratings are stress ratings not to cause damage to the device.
Operation at these ratings is not guaranteed.
2. All of the VDD and Vss pins are external pins. Connect them directly to the power
source and ground.
3. To prevent latch-up tolerance, connect more than one by-pass condenser between
power supply pins and ground. Use at least 0.2 mF condenser.

Setting WDRST to '0' after setting it to '1' clears the watchdog
timer counting value and starts
counting. The watchdog timer
consists of a 17-bit binary
counter counting on the oscillation clock. Therefore, clear the
watchdog timer counting value
within 2 16 (65,536) machine
cycles.
Changing the set value reduces
the wait time for oscillation stabilization when returning from
STOP mode. (At reset release,
the wait time for oscillation stabilization is 216 (65,536) machine
cycles.

The following describes programming rules and precautions in the STOP/HALT mode.
Points for Programming
P
(1) Setting the CPUM address in the address register in advance, set the CPUM register using
the MOV instruction with the register indirect addressing mode.
Q
(2) Immediately after the MOV instruction, locate three NOPs consecutively.
(3) Immediately before the MOV instruction, locate the JMP instruction and align to the even
address. This avoids the effects by the differences of the bus widths in the memory mode

Transmission starts by writing
the data into this register. The
transmission starts after 1 cycle
or 2 cycles of the transmission
clock. In 7-bit transfer, the MSB
(bit 7) is ignored. Writing to
SC0TRB register must be operated after verifying that the transmission is not in progress.
The data is received by reading
this register. The data is read
when an interrupt occurs or the
SC0RXA flag of the SC0STR
register is 1. In 7-bit transfer, the
MSB (bit 7) becomes 0.

A parity error occurs when the
parity bit is 1 although it is set to
0, when the parity bit is 0 although it is set to 1, when the parity bit is odd although it is set to
even, and when the parity bit is
even although it is set to odd.
Parity error data is updated
whenever the parity bit is received.
An overrun error occurs when
the next data is received completely before the CPU reads the
received data (SC0TRB). Overrun error data is updated whenever the last data bit (seventh or
eighth bit) is received.

0, when the parity bit is 0 although it is set to 1, when the parity bit is odd although it is set to
even, and when the parity bit is
even although it is set to odd.
Parity error data is updated
whenever the parity bit is received.
An overrun error occurs when
the next data is received completely before the CPU reads the
received data (SC1TRB). Overrun error data is updated whenever the last data bit (seventh or
eighth bit) is received.

9-5 Initialization Program
After reset, the initialization program must be located in the CS0
area (x'010000' to x'3FFFFF). In the initialization program, set the
number of wait cycles for Block 0 to the MEMMD0 register. Next, set
the MEMCTR register. Always set bits [8:0] of the MEMCTR register
to '100'. The number of wait cycles set in the MEMMD0 register is
valid after setting the MEMCTR register.
; Initialization Program

Setting the MEMMD0 register and
the MEMCTR register must follow
this step. If this step is not followed, writing to the MEMCTR
register cannot be guaranteed.
Recommend to write x'0410' to
MEMCTR_INIT.
In the program, the following symbols and register addresses are
equivalent.
(Amemctr) = (x'FC02')
(Amemmd0) = (x'FC30')
(Amemmd1) = (x'FC32')

9-6 Flash EEPROM Version
9-6-1 Overview
MN102LF61G is equivalent to MN102L610B with 128 KB of internal
Flash EEPROM, which is capable of being programmed /erased
electrically.
MN102LF61G is programmed in one of two modes;
PROM writer mode, which uses a dedicated PROM writer for a
microcontroller's stand-alone programming. Onboard programming mode,
which the CPU controls programming of a microcontroller on a target board.
The 128 KB flash EEPROM is divided into two main areas.
Load program area (6 KB : #0x80000 to #0x817FF)
This area stores a load program for onboard programming mode. This area is
overwritten only in PROM writer mode. This area is write/erase-protected in
the hardware during onboard programming mode.
User program area (122 KB : #0x81800 to #0x9FFFF)
This area stores an user program. It is overwritten in both programming
modes.
Normal operation is guaranteed with up to ten programmings.

Figure 9-6-2 shows the flow for reprogramming (erasing and programming)
the flash memory.
Write 0s to entire memory
Erase routine
ERASE
Reverse
Write user program
Figure 9-6-2 Internal EEPROM Programming Flow
As the figure shows, the write occurs after the memory is completely erased.
The erase routine consists of three steps, first writing all zeros to the entire
memory space, next erasing the memory, and finally reversing.
9-6-3 PROM Writer Programming Mode
In PROM writer mode, the CPU is halted for Internal flash EEPROM to be
programed. Use the dedicated adaptor socket, which connects to the dedicated PROM writer. When the mocrocontroller connects to the adaptor
socket, it automatically enters PROM writer mode.
Flash EEPROM Version
IX-263
Chapter 9 Appendix
9-6-4 Onboard Serial Programming Mode
The onboard serial programming mode is primarily used to program the flash
EEPROM in devices that are already installed on a PCB board with internal
serial interface. Use the dedicated serial writer for programming controlled by
the load program. In this mode, load program is write/erase-protected in the
hardware.
When you use the YDC serial writer, follow the instructions. Standard
onboard serial programming writer comes with load program.
9-6-5 Hardware requirements
1. I/F
Hardware for flash ROM programming on this LSI are as follows.
8-bit serial interface
: 1 set
Data transmission/reception
Transfer bit LSB first
Clock speed over 10 MHz (max.)
Input/output through positive logic
Input/output pin
: 2 pins

1) Serial writer load program area
These 6 KB of ROM, starting at address 0x80000, holds the load program for the
serial writer. This area is write/erase-protected in the hardware.
2) Branch instruction to reset service routine
Normally, reset servicing starts at address 0x80000, but the soft branch instruction
in the serial writer load program branches to 0x81808. This adress must hold a JMP
instruction pointing to the real start address for the reset service routine.
3) Branch instruction to interrupt service routine
Normally, interrupt servicing starts at address 0x80008, but the soft branch instruction in the serial writer load program branches to 0x81810. This adress must hold a
JMP instruction pointing to the real start address for the reset service routine.
4) User program area
This area holds user program.

When VDD is too low, serial writer supplies power to the target board for programming.
When VDD level is too low, serial writer generates error message.
NRST pin outputs microcontroller reset signal.
Connect pull-up resistors on the target board to NRST, SBT, SBD pins, which are connected to
the power supply. The pull-up resistance should be 4.7 kΩ ± 0.47 kΩ (min) to 10 kΩ ± 1 kΩ (max).
NRST, SBT, SBD pins are output from the serial writer through an open connection.

To set up the serial writer interface:
1. At timing A, serial interface writer supplies VDD, and at this time, it outputs
NRST=SBD=Low.
2. Through the serial writer, drive the NRST pin from timing B, when SBT
goes high on microcontroller power-up, for T2 cycles. The microcontroller
initializes.
3. Through the serial writer, drive the NRST pin Low from time C, when SBD
goes high on microcontroller power-up, for T3 cycles. This signals the
microcontroller that it is connected to the serial writer.
4. Make T3 long enough to allow the microcontroller oscillator to stabilize.
