(2) Target Status LEDs
The target status LEDs indicate the target MCU's operating status and target board's power supply. Table 1.4 lists the definition
of each target status LED.
Table 1.4 Definitions of the target status LEDs
Name Status Meaning
ON Power is supplied to the user system. POWER
OFF Power is not supplied to the user system.
ON Target MCU clock is oscillating. CLOCK
OFF Target MCU clock is not oscillating.
ON Target MCU is being reset, or reset signal of the user system is held low. RESET
OFF Target MCU is not being reset.
ON User program is being executed. RUN
OFF User program has been halted.
ON Address 00000h or 00001h has been read out. WARNING
OFF Address 00000h or 00001h has not been read out.
CAUTION
Note on the Target Status POWER LED:
z If your MCU has two or more VCC pins, the LED does not light unless power is supplied to all the pins.
Note on the Target Status CLOCK LED:
z 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 Addresses 00000h and 00001h:
z With the M16C/Tiny Series MCUs, when a maskable interrupt is generated, the interrupt data (interrupt number
and interrupt request level) stored in addresses 00000h and 00001h are read out. Also, the interrupt request bit is
cleared when address 00000h or 00001h is read out. Consequently, when the address 00000h or 00001h readout
instruction is executed or when address 00000h or 00001h 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 or 00001h is generated excluding the interrupt,
the WARNING LED (yellow) on the PC7501 front panel lights up to alarm. When this LED lights, there is a
possibility of read access, therefore check the user program.

system. If you want to debug programs without the user system or change a frequency temporarily, you can check its operation
before preparing an oscillator. If you want to use the internal oscillator circuit of the PC7501 as a main clock, choose
"Generated" in the emulator debugger and specify a frequency you like to use for this clock supplied to an MCU.
Although you can change a frequency between 1.0 and 99.9 MHz by 0.1 MHz for the PC7501, do not specify a value
exceeding the maximum input frequency of the X
of the MCU.

2. Option
Setting the debug options
Specify whether you want to use the internal flash ROM or
the MCU or not.
Check the box when not downloading the program to the
internal flash ROM of the MCU. Initially, this option is
deselected. If this box is checked, the number of write/erase
cycles of the internal flash ROM will be unlimited, and
working efficiency (downloading, software break, etc.) will
be improved because the program is downloaded in the
emulation memory in the PC7501. However, maximum
operating frequency is 10MHz.
3. MCU Status

listed in block units.
- Any block which has had its check box selected is not
cleared when downloading. The memory content of this
block remains intact unless overwritten by downloading.
- Any block which has had its check box deselected is
cleared when downloading.
- Click the Select All button, and all blocks will be
selected (marked by a check mark, so that none of the
blocks is cleared when downloading).
- Click the Clear All button, and all blocks will be

(3) Setting breakpoints
1. Screen after breakpoint setup
Breakpoint setup screen
There are three types of breakpoints as described below.
- Address match breakpoint (A)
This breakpoint can be set only when you check “Enable
the Address Match Interrupt Break Function.” on the
MCU tab of the Init dialog box.
A breakpoint can be set or cleared by double-clicking in
the address match breakpoint display area in the editor
(source) window. (A blue circle is displayed at the setting
line)
Up to six breakpoints can be set.
The address match break causes the program to stop
before executing the address at which a breakpoint is set.
- Software breakpoint
A software breakpoint can be set or cleared by double-
clicking the software breakpoint display area in the editor
(source) window (A red circle is displayed at the setting
line).
This is rewritten to a break instruction, therefore, because
of rewriting flash ROM, program execution starts with a
delay of several seconds after setting ROM area.
If the breakpoint you set is a software breakpoint, the
program stops before executing the instruction at the set
breakpoint.
- Hardware breakpoint
A hardware breakpoint can be set or cleared by right-
clicking the breakpoint display area.
If the breakpoint you set is a hardware breakpoint, the
program stops after executing the instruction at the set
breakpoint (after several cycles).

4.2 Differences between the Actual MCU and Emulator
Differences between the actual MCU and emulator are shown below. When debugging the MCU using this product, be careful
about the following precautions.
IMPORTANT
Note on Differences between the Actual MCU and Emulator:
z 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
Initial values are different. Set them in the user program.
(3) Interrupt stack pointer (ISP) after a reset is released
Initial values are different. Set them in the user program.
(4) Capacities of the internal memories (ROM and RAM)
The evaluation MCU of this product has RAM of 12KB (00400h--033FFh) and flash ROM of 4KB
(0F000h--0FFFFh) and 128KB (E0000h--FFFFFh).
The number of write/erase cycles of the internal flash ROM of the MCU is limited. If you use the
emulation memory instead of the internal flash ROM of the evaluation MCU, the number of write/erase
cycles will be unlimited. However, the maximum operating frequency is 10 MHz.
(5) Oscillator circuit
In the oscillator circuit where an oscillator is connected between pins X
occur because a package converter board is used between the evaluation MCU and the user system. For
notes on when using an oscillator circuit on the user system, refer to "2.11.3 Using the Oscillator Circuit on
the User System " (page 41). It is same for pins X
CIN
and X
COUT
.
(6) Xin input when resetting the MCU
With the target MCUs, an oscillator circuit is initialized during reset execution, and an on-chip oscillator is
changed to system clock. Therefore, the emulator system can be operated without a clock to the pin Xin.
With an evaluation MCU, when resetting the MCU, it is necessary to input a clock to the pin Xin before
the emulator control program changes the on-chip oscillator to the system clock.
(7) A/D conversion
The characteristics of the A/D converter differ from those of actual MCU because there are a package
converter board and other devices between the evaluation MCU and the user system.
(8) Operation after releasing the reset
After releasing the reset, for about up to 350 cycles, a program to control the emulator will be executed.
Note that this will have an affect on a user program execution time and tracing result.
Note on RESET# Input:
z A low input to pin RESET# from the user system is accepted only when a user program is being executed (only
while the RUN status LED on the PC7501's upper panel is lit).
Note on NMI# Input:
z A low input to pin NMI# from the user system is accepted only when a user program is being executed (only
while the RUN status LED on the C7501's upper panel is lit).

M3028BT-EPB User’s Manual 4. Hardware Specifications
IMPORTANT
Note on Voltage Detect Circuit:
z As the power voltage cannot be changed after powering on the user system, the voltage detect circuit (voltage
down detect interrupt and hardware reset 2) cannot be used with this product.
Notes on Reset Vector Area:
z 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.
z You can change data in the reset vector area only when the user program is stopped.
z 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.
Notes on Stack Area:
z 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.
z 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 Maskable Interrupts:
z 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.
z 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 DMA Transfer:
z 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
Note on Final Evaluation:
z 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.

M3028BT-EPB User’s Manual 4. Hardware Specifications
IMPORTANT
Note on Clock Supply to an MCU:
z 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 user system clock and that of the user program execution.
(2) When "External" is selected:
A clock generated by the oscillator in the user system is supplied. It depends on the status of the oscillation
(on/off) of the user 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 user system clock and that of the user program execution.
Note on Operating Frequency:
z You can not use this product with a main clock (XIN-XOUT) less than 1MHz. To use it with a main clock less
than 1MHz, contact your local distributor.
Note on Timeout Setting:
z At 8MHz or less, when you download, execute or single-step a program at a low operating frequency, a
communication timeout error may occur.
Execute the command shown below in the Script Window after starting the emulator debugger.
[Command] _settimeout 300, 300
Once this command is executed, it remains effective the next time you start the emulator debugger. Therefore,
you do not need to execute this command again. It is set to 30 seconds for downloading, and 30 seconds for
other than downloading.
If the error still occurs in this setting, contact your local distributor.
Note on Stop and Wait Modes:
z Do not single step an instruction shifting to stop or wait mode. It may cause communication errors.
Note on the Watchdog Function:
z If the reset circuit of the user system has a watchdog timer, disable it when using the emulator.
Note on Protect Register:
z 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

IMPORTANT
Note on Access Prohibited Area:
z You cannot use internally reserved areas. Write signals to the areas will be ignored, and values read will be
undefined.
Note on Breaks:
z The area displaying break points in the program window of the emulator debugger shows the following breaks.
(1) Address-match break
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
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
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 (after several cycles).
Notes on Software Breaks:
z 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.
z The BRK instruction can be used for the emulator only. You cannot use it in a user program.
z 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.
Notes on Address-Match Breaks:
z 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.
z Address-match breaks can be set at up to six points. The other breaks are set as software breaks.
z Address-match breaks can be set or canceled even when the user program is being executed.
Notes Power Supply to the User System:
z Pin VCC is connected in order to monitor user system voltage. For this reason, the emulator cannot supply
power to the user system. Therefore, provide the user system with a separate power supply.
z The voltage of the user system should be as follows.
2.7 V ≤ VCC ≤ 5.5 V
z Do not change the voltage of the user system after turning on the power.

M3028BT-EPB User’s Manual 4. Hardware Specifications
IMPORTANT
Notes on Internal Flash ROM of the MCU:
z This product downloads a user program to the flash ROM in an MCU. 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 10MHz.
z 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.
z If the following errors occur frequently when downloading a program, To purchase products for replacement,
contact your local distributor.
(1) Flash ROM erase error occurred ERROR (16258)
(2) Flash ROM verify error occurred ERROR (16259)
Note on Debugging in CPU Rewrite Mode:
z When debugging in CPU Rewrite Mode, check "Debug the program using CPU Rewrite Mode" in the MCU tab
of the Init dialog box of the emulator debugger.
Note on Debugging in CPU Rewrite Mode:
z When you debug M16C/Tiny Series MCUs in CPU rewrite mode, do not change the block 0 area (FF000h--
FFFFFh) of the flash ROM. Otherwise, the emulator will be uncontrollable.
z 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
z Do not stop the program in the CPU rewrite mode or erase suspend mode. And do not single step the instruction
shifting to these modes. The emulator is uncontrollable in these modes.
z The data written in the CPU rewrite mode cannot be referenced during the user program is being executed. 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.
z 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)

M3028BT-EPB User’s Manual 4. Hardware Specifications
IMPORTANT
Notes on Address-Match Interrupts:
z 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.
z 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.
z 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.
Note on Accessing Addresses 00000h and 00001h:
z With the M16C/Tiny Series MCUs, when a maskable interrupt is generated, the interrupt data (interrupt number
and interrupt request level) stored in addresses 00000h and 00001h are read out. Also, the interrupt request bit is
cleared when address 00000h or 00001h is read out. Consequently, when the address 00000h or 00001h readout
instruction is executed or when address 00000h or 00001h 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 or 00001h is generated excluding the interrupt,
the WARNING LED (yellow) lights up to alarm. When this LED lights, there is a possibility of read access,
therefore check the user program.
Note on Debugging Operations after Releasing a Reset form the User System:
z Do not execute debugging operations (such as stopping the user program execution by an address-match,
software or hardware break, run-time debugging) after releasing a reset on the user system until an interrupt
stack pointer (ISP) is set in the user program.
