the trouble.
(1) Press the system reset switch on the emulator front panel.
(2) If normal operation is not restored after step (1), shut OFF power to the emulator once and then
reactivate it.
Caution to Be Taken for External Trigger Input Voltage:
• Keep an external trigger input voltage of the emulator main unit less than a Vcc2 voltage.
Overvoltage may cause damage to the internal circuits.
( 10 / 80 )
IMPORTANT
Notes on Downloading Firmware:
• Before using this product for the first time, it is necessary to download the dedicated firmware.
Please note that, to do this, it is necessary to start up the emulator main unit in maintenance mode.
For downloading firmware, see "4.2 Downloading Firmware" (page 48). Once the firmware has
been downloaded, the product can be used by simply turning on the power.
• Do not shut off the power while downloading the firmware. If this happens, the product will not
start up properly. If the power is shut off unexpectedly, redownload the firmware.
• Download the firmware with the target system not connected.
Notes on Self-check:
• If the self-check does not result normally (excluding target system errors), the emulation probe may
be damaged. Then contact your local distributor.
• Run the self-check with the target system not connected.
Note on Quitting the Emulator Debugger:
• To restart the emulator debugger, always shut power to the emulator module off once and then on
again.
Note on Final Evaluation:
• Be sure to evaluate your system with an evaluation MCU. Before starting mask production,
evaluate your system and make final confirmation with a CS (Commercial Sample) version MCU.
Notes on Power Supply to the Target System:
• Pins Vcc1 and Vcc2 are connected to the target system to observe the voltage. Therefore, the power
is not supplied to the target system from the emulator, design your system so that the target system
is powered separately.
• The voltage of the target system should be as follows.
(1) When JP1 is set as Vcc1 = Vcc2:
2.7 V ≤ Vcc1 = Vcc2 ≤ 5.5 V
(2) When JP1 is set as Vcc1 > Vcc2:
4.8 V ≤ Vcc1 ≤ 5.2 V
2.7 V ≤ Vcc2 < Vcc1
•Do not change the voltage of the target system after turning on the power.
Note on RESET* Input:
•A low input to pin RESET* from the target system is accepted only when a user program is being
executed (when the RUN status LED on the PC7501's front panel is lit).
( 11 / 80 )
IMPORTANT
Note on NMI* Input:
•A low input to pin NMI* from the target system is accepted only when a user program is being
executed (when the RUN status LED on the PC7501's front panel is lit).
Note on RDY* Input:
• Be sure to input a low to pin RDY* of the target system during the user program execution (only
while the RUN status LED on the PC7501's upper panel is lit). Inputting a low signal to pin RDY*
when the user program is stopped may cause a malfunction of the emulator.
Note on HOLD* Input:
• Be sure to input a low to pin HOLD* of the target system during the user program execution (only
while the RUN status LED on the PC7501's upper panel is lit). Inputting a low signal to pin HOLD*
when the user program is stopped may cause a malfunction of the emulator.
Notes on Maskable Interrupts:
• Even if a user program is not being executed (including when run-time debugging is being
performed), the evaluation MCU keeps running so as to control the emulation probe. Therefore,
timers and other components do not stop running.
If a maskable interrupt is requested when the user program is not being executed (including when
run-time debugging is being performed), the maskable interrupt request cannot be accepted,
because the emulator disables interrupts. The interrupt request is accepted immediately after the
user program execution is started.
• Take note that when the user program is not being executed (including when run-time debugging
is being performed), a peripheral I/O interruption is not accepted.
Note on Clock Supply to the MCU:
•A clock supplied to the evaluation MCU is selected by the Emulator tab in the Init dialog box of
the emulator debugger.
(1) When "Internal" is selected:
A clock generated by the oscillator circuit board in the PC7501 is supplied. It is continually
supplied regardless of the status of the target system clock and that of the user program
execution.
(2) When "External" is selected:
A clock generated by the oscillator in the target system is supplied. It depends on the status
of the oscillation (on/off) of the target system.
(3) When "Generate" is selected:
A clock generated by the dedicated circuit in the PC7501 is supplied. It is continually supplied
regardless of the status of the target system clock and that of the user program execution.
( 12 / 80 )
IMPORTANT
Note on Access Prohibited Area:
• You cannot use internally reserved areas. Write signals to the areas will be ignored, and values read
will be undefined.
Notes on Stack Area:
• With this product, a maximum 8 bytes of the user stack is consumed as a work area.
Even if the user stack does not have an enough area, do not use areas which cannot be used as a stack
(SFR area, RAM area which stores data, or ROM area) as a work area. Using areas like this is a cause
of user program crashes and destabilized emulator control.
• With this product, the interrupt stack pointer (ISP) is set at 00500h and used as a stack area after
a reset is released.
Notes on Reset Vector Area:
• Memory in the emulator main unit is always selected as a reset vector area (FFFFCh--FFFFFh) in
order to operate the evaluation MCU in the emulator-dedicated mode. Set the contents of the reset
vector area in one of the following ways.
(1) Download a user program to an area including the reset vector area.
(2) Set the reset vector using a memory window of the emulator debugger etc.
• You can change data in the reset vector area only when the user program is stopped.
• Do not access the reset vector area as data. It may not be accessed properly, and the program may
not run properly in the next bus cycle.
Note on Accessing Address 00000h:
• With the M16C Series MCUs, when a maskable interrupt is generated, the interrupt data (interrupt
number and interrupt request level) stored in address 00000h is read out. Also, the interrupt request
bit is cleared when address 00000h is read out. Consequently, when the address 00000h readout
instruction is executed or when address 00000h is read out in the cause of a program runaway, a
malfunction occurs in that the interrupt is not executed despite the interrupt request, because the
request bit of the highest priority interrupt factor enabled is cleared.
For this malfunction, when the reading out to address 00000h is generated excluding the interrupt, the
WARNING LED (yellow) lights up to alarm. When this LED lights, there is a possibility of wrong
access, therefore check the user program.
Note on Stop and Wait Modes:
• Do not single step an instruction shifting to stop or wait mode. It may cause communication errors.
( 13 / 80 )
IMPORTANT
Note on Display of MCU Status:
•"MCU status" you can refer to in the MCU tab of the MCU Setting dialog box of the emulator
debugger shows pin levels of the target system. Make sure that proper pin levels are specified
according to the mode you use.
(1) When single-chip mode is used:
CNVss: Low
(2) When memory expansion mode 16-bit data bus width is used:
CNVss: Low, BYTE: Low, HOLD*: High, RDY*: High
(3) When memory expansion mode 8-bit data bus width is used:
CNVss: Low, BYTE: High, HOLD*: High, RDY*: High
(4) When microprocessor mode 16-bit data bus width is used:
CNVss: High, BYTE: Low, HOLD*: High, RDY*: High
(5) When microprocessor mode 8-bit data bus width is used:
CNVss: High, BYTE: High, HOLD*: High, RDY*: High
Note on Breaks:
• The area displaying break points in the program window of the emulator debugger shows the
following breaks.
(1) Address-match break "A"
This is a debugging function which breaks a program, using the address-match interrupt
function of the MCU, immediately before the system executes an instruction at a specified
address. The instruction at the preset address will not be executed.
(2) Software break "B"
This is a debugging function which generates a BRK interruption by changing an instruction
at a specified address to a BRK instruction (00h) to break a program immediately before the
system executes an instruction at a specified address. The instruction at the preset address will
not be executed.
(3) Hardware break "H"
This is a debugging function which breaks a program by setting the detection of an execution
of an instruction at a specified address as a break event. The program will break after the
instruction at the specified address is executed.
Notes on Address-Match Breaks:
• As the processing speed of setting and canceling address-match breaks is relatively fast, you can
save the times of writing into the internal flash ROM of an MCU. Therefore, address-match breaks
precede the other breaks when setting breakpoints in the internal flash ROM area of an MCU.
•Address-match breaks can be set only in RAM and ROM areas of an MCU.
• Address-match breaks can be set at up to four points. The other breaks are set as software breaks.
•Address-match breaks can be set or canceled even when the user program is being executed.
( 14 / 80 )
IMPORTANT
Notes on Address-Match Interrupts:
•When you use the address-match interrupt function in a user program, uncheck "Enable the Address
Match Interrupt Break Function" in the MCU tab of the Init dialog box of the emulator debugger.
Thus, normal software breaks are used for the internal RAM and ROM areas of an MCU.
• Do not set a software break at an address where an address-match interrupt occurs. Otherwise, a
user program may be run out of control. Set a software or hardware break in the top address in
address-match interrupt processing.
• When you single step an address where an address-match interrupt occurs, the program stops after
executing the first instruction after returning from address-match interrupt processing.
Notes on Software Breaks:
• Software breaks change the instruction at a specified address to a BRK (00h). Therefore, take note
that when you reference the result of a trace in bus mode, "00h" is displayed.
• The BRK instruction can be used for the emulator only. You cannot use it in a user program.
• You can neither set nor cancel a software breakpoint in the internal ROM area of an MCU during
user program execution, while you can set or cancel it in the internal RAM area of an MCU and
the area (emulation memory) where the map setting is INTERNAL in chip-select CS3* to CS0*.
( 15 / 80 )
IMPORTANT
Note on Differences between the Actual MCU and Emulator:
•Operations of the emulator system differ from those of actual MCUs as listed below.
(1) Reset condition
Set the time for starting up (0.2 Vcc to 0.8 Vcc) 1 µs or less.
(2) Initial values of internal resource data of an MCU at power-on
(3) Interrupt stack pointer (ISP) after a reset is released
(4) Capacities of the internal memories (ROM and RAM)
The evaluation MCU of this product has RAM of 31 KB (00400h--07FFFh) and flash ROM
of 4 KB (0F000h--0FFFFh) and 384 KB (A0000h--FFFFFh).
(5) Oscillator circuit
In the oscillator circuit where an oscillator is connected between pins XIN and XOUT, oscillation
does not occur because a converter board is used between the evaluation MCU and the target
system. It is same for pins XCIN and XCOUT. For notes on when using the oscillator circuit on
the target system, refer to "3.1.3 Using the Oscillator Circuit on the Target System" (page 29).
(6) A-D conversion
The characteristics of the A-D converter differ from those of actual MCU because there are
a converter board and other devices between the evaluation MCU and the target system.
(7) Ports P0 to P5, P10
This product emulates some I/O ports (P0 to P5, P10). Therefore, the electrical characteristics
of these ports differ from those of an actual MCU.
(8) Address and status of BHE*
When the internal RAM or ROM area of an MCU is accessed during user program execution,
actual MCUs retain a preceding address and status of BHE*, while this product does not.
(9) Status of a data bus
In stop or wait mode, actual MCUs retain a preceding status of a data bus, while with this
product a data bus is floating.
Note on the Watchdog Function:
• If the reset circuit of the target system has a watchdog timer, disable it when using the emulator.
Note on DMA Transfer:
•With this product, the program is stopped with a loop program to a specific address. Therefore, if
a DMA request is generated while the program is stopped, DMA transfer is executed. However,
make note that DMA transfer while the program is stopped may not be performed correctly. Also
note that the below registers have been changed to generate DMA transfer as explained here even
when the program is stopped.
(1) DMA0 transfer counter: TCR0
(2) DMA1 transfer counter: TCR1

IMPORTANT
Note on Protect Register:
• The protect is not canceled when bit 2 of protect register PRCR (PRC2), which enables writing into
the port P9 direction register and the SI/Oi control register, is changed with the below procedure.
(1) Step execution of an instruction setting PRC2 to "1"
(2) Setting a break point between an instruction setting PRC2 to "1" and a point where the port
P9 direction register or the SI/Oi control register is set
(3) Setting PRC2 to "1" by the memory window or script window
Notes on Pullup Control:
•Because this product emulates some I/O ports (P0 to P5, P10), you can not pullup ports P0 to P5
by the pullup control registers. Install the included resistor arrays (51 kΩ) as necessary.
• The initial value of pullup control register 1 PUR1 of this product is different from that of an actual
MCU. When a Vcc level is input to pin CNVss, the value of an actual MCU is "02h" (bit 1 PU11
is "1"), while that of this product is "00h".
Note on Operating Frequency:
•You can not use this product with a main clock (XIN-XOUT) less than 1 MHz. To use it with a main
clock less than 1 MHz, contact your local distributor.
Notes on Internal Flash ROM of the MCU:
• This product downloads a user program to the flash ROM in an MCU when debugging in singlechip or memory expansion mode. By checking "Disable the Internal Flash ROM" in the MCU tab
of the MCU setting dialog box of the emulator debugger, you can disable the operation of the
internal flash ROM of the MCU to use the emulation memory. However, the maximum operating
frequency is 10 MHz.
•Because the number of write/erase cycles of the internal flash ROM of the MCU is limited, it must
be replaced at the end of its service-life.
• If the following errors occur frequently when downloading a program, replace the MCU board.
(1) Flash ROM erase error occurred ERROR (16258)
(2) Flash ROM verify error occurred ERROR (16259)
To purchase products for replacement, contact your local distributor.

IMPORTANT
Notes on Debugging in CPU Rewrite Mode:
• When you debug an M16C/62P MCU of the M16C/62 group in CPU rewrite mode, do not change
the block 0 area (FF000h--FFFFFh) of the flash memory. Otherwise, the emulator will be
uncontrollable.
• If you check "Debug the program using CPU Rewrite Mode" in the MCU tab of the Init dialog box
of the emulator debugger, you cannot use the following functions.
(1) Setting software breakpoints in an internal ROM area
(2) Executing COME in an internal ROM area
• In the rewrite control program area (from setting CPU rewrite mode to releasing it), do not use the
following functions.
(1) Single-stepping
(2) Setting software breakpoints
(3) Setting hardware breakpoints
• To reference data after executing CPU rewrite, stop the program at a point which is not a rewrite
control program area and use a memory window etc.
• As the following interrupt vectors are used by the emulator system, the read data is different from
expected value.
(1) BRK instruction (FFFE4h--FFFE7h)
(2) Address match (FFFE8h--FFFEBh)
(3) Single-step (FFFECh--FFFEFh)
(4) DBC (FFFF4h--FFFF7h)

IMPORTANT
Note on Usage in Memory Expansion or Microprocessor Mode:
•When you use this product in memory expansion or microprocessor mode, be sure
to design your system so that pins RDY* and HOLD* are not active at startup.
Otherwise, it cannot startup normally.
Note on the Target Status POWER LED:
• If your MCU has two or more Vcc terminals, the LED does not light unless power
is supplied to all the terminals.
Note on the Target Status CLOCK LED:
• If the LED is not turned on, check the following.
(1) After powering on the PC7501 (before starting up the emulator debugger):
Make sure that the oscillator circuit board is properly installed in the PC7501 and
it is oscillating normally.
(2) After the emulator debugger is started up (after the Init dialog box settings are
completed):
Make sure that the oscillator selected in the Init dialog box is oscillating normally.
Note on Accessing Address 00000h:
• With the M16C Series MCUs, when a maskable interrupt is generated, the interrupt
data (interrupt number and interrupt request level) stored in address 00000h is read
out. Also, the interrupt request bit is cleared when address 00000h is read out.
Consequently, when the address 00000h readout instruction is executed or when
address 00000h is read out in the cause of a program runaway, a malfunction occurs
in that the interrupt is not executed despite the interrupt request, because the request
bit of the highest priority interrupt factor enabled is cleared.
For this malfunction, when the reading out to address 00000h is generated excluding
the interrupt, the WARNING LED (yellow) lights up to alarm. When this LED
lights, there is a possibility of wrong access, therefore check the user program.
