(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:

 With the M16C/60 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 wrong read access, therefore check the user program.

2.11.3 Using the Oscillator Circuit on the User System

To operate this product with an external clock, construct the oscillator circuit as shown in Figure 2.17 in the user system and

input the oscillator output at 50% duty (within the operating range of the evaluation MCU) into pin X

. And pin X

OUT

should

be open. Choose "External" in the emulator debugger to use this clock.

Figure 2.17 External oscillator circuit

Make note that in the oscillator circuit shown in Figure 2.18 where a resonator is connected between pins X

and X

oscillation does not occur because a converter board and other devices are used between the evaluation MCU and the user

system. It is same for sub-clock oscillator circuits (X

CIN

and X

COUT

Figure 2.18 Circuit in which oscillation does not occur

2.11.4 Using the Internal Generator Circuit

The dedicated circuit in the PC7501 can generate any arbitrary frequency specified by the emulator debugger, and it can be

supplied as a main clock. It does not depend on either the oscillator circuit board in the PC7501 or the oscillator circuit on the

user system. If you want to debug programs without the user system or change a frequency temporarily, you can check its

operation before purchasing an oscillator. If you want to use the internal generator circuit in the PC7501 as a main clock,

choose "Generate" in the emulator debugger and specify a frequency you like to use this clock.

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 an MCU.

IMPORTANT

Note on Using the Internal Generator Circuit:

 The internal generator circuit is equipped for temporary debugging purposes. Temperature characteristics of

frequencies are not guaranteed.

 Be sure to evaluate your system with an oscillator or oscillator module whose frequency is same as that of the

internal oscillator circuit (internal clock) for final evaluation purposes.

Editor (Source) window

The editor (source) window is a window that always

shows the content of the source file corresponding to the

current position of the program counter. It automatically

opens when the emulator starts up. The program counter

position is identified by the yellow background color.

Here, you can execute the program up to the cursor

position, set or clear software breakpoints, and line-

assemble the source file.

Because the present emulator uses the MCU’s internal flash ROM, the initial value for the ROM area data at the time of purchase is “FFh.”

CPU reset

Resets the CPU.

Runs the program beginning with the current PC position.

Reset Go

Runs the program after reset.

Step In

Single-steps the program executing each statement (including those in functions).

Step Over

Single-steps the program executing each function call as one step.

Step Out

Exists a function and stops at a statement in the program next to the one that called the function.

STOP

(3) Setting break points

1. Screen after software breakpoint setup

Breakpoint setup screen

There are three types of breakpoints as described

below.

- Address match breakpoint

This breakpoint can be set only when you chose to

use the address match 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 eight breakpoints can be set. When this

limit is exceeded, software breakpoints are 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) Setting the combinatorial event condition

1. Window for setting the combinatorial event condition

Setting the combinatorial event condition

There are following four conditions that you can choose for

the combinatorial events.

- AND

The program breaks when all of the specified events

occur.

- AND (Same Time)

The program breaks when the specified events occur at

the same time.

- OR

The program breaks when one of the specified events

occurs.

- STATE TRANSITION

The program breaks when the state transition diagram

goes into the break state.

For each event, a pass count (number of passing) is

specifiable (1--255). When “AND” (same time) is specified

for Combination, you can not specify the pass count (fixed

to one).

When you have finished setting the combinatorial event condition, click the “Set” button.

Trace window

The trace window is used to show the results of real-time trace

measurements. It has the following four display modes:

- Bus mode

Bus information per cycle can be inspected. The contents are

displayed in order of execution paths.

- Disassemble + data access mixed mode

The executed instruction and the content of the accessed data

can be inspected together. Contents are displayed in order of

the execution paths.

- Disassemble mode

The execution paths of the executed instructions can be

inspected. The contents are displayed in order of execution

paths.

- Source mode

The execution paths of the source program can be inspected.

These modes can be switched over using the respective toolbar

buttons.

The trace window shows the measurement result when a real-

time trace measurement has finished. The trace window

remains blank until the real-time trace measurement in

progress finishes.

4.3 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:

 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, RAM, OSDRAM and OSDROM) The evaluation MCU of this product has RAM of 16 KB (00400h--043FFh) and flash ROM of 4 KB

(0F000h--0FFFFh) + 512 KB (80000h--FFFFFh), OSDRAM of 4 KB (8000h--8FFFh) and OSDROM of

128KB (30000h--4FFFh). (5) Oscillator circuit In the oscillator circuit where an oscillator is connected between pins X

occur because a converter board is used between the evaluation MCU and the user system. It is same for

pins X

CIN

and X

. For notes on when using the oscillator circuit on the user system, refer to "2.11.3

COUT

Using the Oscillator Circuit on the User System " (page 42). (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 user 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. (10) Operation after releasing the reset After releasing the reset, for about max. 380 cycles, a program to control the emulator will be executed.

Note that this will be included in the user program execution time and tracing result.

Note on RESET* Input:

 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 emulator's upper panel is lit).

Note on RDY* Input:

 Be sure to input "L" to pin RDY* of the user system during the user program executing (when the RUN status

LED on the PC7501's upper panel is lit). Inputting "L" to pin RDY* during the user program stopping may cause a malfunction of the emulator.

Note on HOLD* Input:

 Be sure to input "L" to pin HOLD* of the user system during the user program executing (when the RUN status

LED on the PC7501's upper panel is lit). Inputting "L" to pin HOLD* during the user program stopping may cause a malfunction of the emulator.

M306V8T-EPB User’s Manual 4. Hardware Specifications

IMPORTANT

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.

 A reset vector area can be changed only when a program is stopped.

 Do not access the rest 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:

 With this product, a maximum 8 bytes of the user stack is consumed as a work area. Therefore, ensure the +8

byte maximum capacity used by the user program as the user stack area. If the user stack does not have enough area, do not use areas which cannot be used as stack (SFR area, RAM area which stores data, or ROM area) as 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 to 00500h and used as stack area after the reset is

released.

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 DMA Transfer:

 With this product, the user program is stopped with a loop program to a specific address. Therefore, if a DMA

request is generated by a timer or other source while the user program is stopped, DMA transfer is executed. However, make note of the fact 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 user program is stopped. (1) DMA0 transfer count register TCR0 (2) DMA1 transfer count register TCR1

REJ10J0777-0100 Rev.1.00 2005.08.01 Page 71 of 90

M306V8T-EPB User’s Manual 4. Hardware Specifications

IMPORTANT

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 Setting "1" to Protect Bit 2 (PCR2) with Sub Clock:

 When the CPU clock is set to the sub-clock (low-speed mode or low power dissipation mode), even if you

enable the PRC2 bit, writing to the register protected by the PRC2 bit (PD9, address 0362h and 0366h registers) cannot be done properly. When you enable the PRC2 bit and write to the register protected by the PRC2 (PD9, address 0362h and 0366h registers), do not set the CPU clock to the sub-clock.

Note on Setting "1" to Protect Bit 2 (PRC2) in Division by 2 Mode:

 Under the following conditions, even if you enable the PRC2 bit, writing to the register protected by the PRC2

bit (PD9, address 0362h and 0366h registers) cannot be done properly. (1) Between when stop mode is released and when a hardware reset is executed (2) Between when low power dissipation mode is enabled and when a hardware reset is executed Therefore, if the condition (1) or (2) applies, when you enable the PRC2 bit and write to the register protected by the PRC2 (PD9, address 0362h and 0366h registers), set the CPU clock neither to the main clock in division by 2 mode nor to the on-chip oscillator clock in division by 2 mode.

Note on the Input Thresholds for the Pins P1_5/D13/INT3, P1_6/D14/INT4 and P1_7/D15/INT5

 With this product, regarding pins P1_5/D13/INT3, P1_6/D14/INT4 and P1_7/D15/INT5, a device which port or

data bus inputs to and a device which INT interrupt inputs to are different as follows:

Device which port or data bus inputs to: Port emulation FPGA (input level: TTL) Device which INT interrupt inputs to: Evaluation MCU for emulating peripheral functions (input level:

CMOS Schmidt) Therefore, the port input level can be read as “H” immediately after an INT interrupt (falling), and the port input level can be read as “H” immediately before an INT interrupt (rising).

IMPORTANT

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 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:

 You can not use this product with a main clock (XIN-X

than 1 MHz, contact your local distributor.

Notes on Map Settings:

 Be sure to set the OSDRAM area (8000h -- 8FFFh) to INTERNAL.

 Be sure to set the OSDROM area (30000h -- 4FFFFh) to EXTERNAL.

Note on Stop and Wait Modes:

 Do not single step an instruction shifting to stop or wait mode. It may cause communication errors.

Note on the Watchdog Function:

 If the reset circuit of the user system has a watchdog timer, disable it when using the emulator.

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.

Note on Protect Register:

 The protect is not canceled when bit 2 of protect register PRCR (PRC2), which enables writing into the PD9,

address 0362h and 0366h registers, 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 PD9, address 0362h

M306V8T-EPB User’s Manual 4. Hardware Specifications

IMPORTANT

Note on Breaks:

 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.

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 or an area where chip select CS3* to CS0* are set to INTERNAL (emulation memory).

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 eight 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.

Notes on Power Supply to the User System:

 Pins Vcc1 and Vcc2 are connected to the user system to observe the voltage. Therefore, the power is not

supplied to the user system from the emulator, design your system so that the user system is powered separately.

 The voltage of the user system should be as follows.

3.15 V ≤ Vcc1 = Vcc2 = Vcc3 ≤ 3.45 V

 Do not change the voltage of the user system after turning on the power.

IMPORTANT

Notes on Internal Flash ROM of the MCU:

 In single-chip mode and memory expansion modes, this product downloads a user program to the flash ROM of

an MCU. By checking "Debug Option" 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. The maximum operating frequencies are as follows. (1) "Debug Option " unchecked

Access area: Flash ROM of MCU Max. operating frequency: 16 MHz (0 wait, 1 wait)

(2) "Debug Option " checked

Access area: Emulation memory of the PC7501 Max. operating frequency: 10 MHz (0 wait, 1 wait)

 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.

Note on Memory Area Expansion Function (Normal Mode):

 During debugging in memory expansion mode or microprocessor mode with this product, the emulation

Note on Memory Area Expansion Function (4-MByte Mode):

memory can be allocated. The emulation memory can be specified up to 4 areas by 4 MB in the MAP tab of the MCU setting dialog box of the emulator debugger.

Each maximum operating frequency is as follows.

- Maximum operating frequency (at 3.3 V) 0 wait: 6 Hz 1 wait to 3 wait: 16 MHz

 When using the memory area expansion function (4-Mbyte mode), please note that the memory to which the

evaluation MCU is connected differs depending on processor modes and debugger settings. For details, refer to the table below. Areas connected when using the memory area expansion function (4-Mbyte mode)

IMPORTANT

Notes on Debugging in CPU Rewrite Mode:

 When you debug an M16C/60 Series MCUs 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 CPU rewrite mode and erase suspend mode, do not stop the program. And do not single step an instruction

shifting to CPU rewrite mode or erase suspend mode. The emulator will be uncontrollable in CPU rewrite mode and erase suspend mode.

 To reference data after executing CPU rewrite, stop the program at other then a rewrite control program area

and use the 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)

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.

Note on Accessing Addresses 00000h and 00001h:

 With the M16C/60 Series MCUs, when a maskable interrupt is generated, the interrupt data (interrupt number
