( 9 / 48 )

IMPORTANT

Notes on PC4701 Emulators:

The PC4700H emulators whose serial number ends with a number cannot be used with M306V0T- RPD-E. Use only products whose serial number ends with a letter of the alphabet. The serial number is on the bottom of the PC4700H.

Example: 5KE100 ........ Can NOT be used with M306V0T-RPD-E.

Requires an upgrade.

Example: 5LE123B ...... Can be used with M306V0T-RPD-E.

Do not turn off the power when downloading firmware. If the emulator is powered off in the middle of the process, it will become unable to start up normally. In cases when the power is inadvertently shut off, re-execute downloading.

Notes on Abnormal Operation:

If the PC4701 system does not pass all self-checks (excluding when an target system error occurs), there is the possibility of trouble in the system. In such case, contact the place of purchase.

Please take note that self-check should be executed under the following conditions.

(1)The target system is not connected.

(2)The Switch SW6 is set to 'L' position, SW7 to '16' (see Chapter 4).

If the emulator malfunctions due to external interference or some other causes, follow the steps given below.

(1)Press the system reset switch located on the front panel of the emulator.

(2)If the emulator does not return to the normal operation despite the step (1) above, turn off the power source of the emulator, turn it on again.

Notes on Target System:

Because the emulation pod does not have the capacity to supply power to other devices, design your system so that the emulator MCU is powered by the target system.

Make sure that the target's supply voltage is within the MCU specification and in the range of +4.5 to 5.5 V.

Do not change power supply voltage of the target system after activating the power.

Before turning on power to anything, check the host machine, emulator main unit, emulation pod, conversion board and user's target system are properly connected. Activate power to units as explained here following.

(1)Turn on and off power to the target system, and then the PC4701 continuously.

(2)After turning on power to the PC4701, check the Target Status LEDs on the emulator' front panel to see if the M306V0T-RPD-E is ready to operate.

Is the power supplied? Check that Target Status LED (POWER) is on.

Is the reset released? Check that Target Status LED (RESET) is off.

( 10 / 48 )

IMPORTANT

Notes on Connecting Target System:

When connecting the FLX100 flexible cable and the converter board, be careful not to forcibly press the connector top of the converter board. (The flexible cable and the converter board are guaranteed for only 20 insertion/removal iterations.)

Especially be careful not to insert the converter board in the wrong direction.

Note on Reset Input from Target System:

The reset input from the target system is accepted only during program execution (while the RUN signal lamp on the PC4701 is lit).

Note on HOLD Input from Target System:

Input an 'L' level signal into the HOLD pin only during program execution. Doing so while the program is stopped or during run time debugging may cause the emulator to malfunction.

Note on Address 0 Access:

With M16C/6V group MCUs, when a maskable interrupt is generated, the interrupt data (interrupt number and interrupt request level) stored in address 0 is read out.

Also, the interrupt request bit is cleared when address 0 is read out. Consequently, when the address 0 readout instruction is executed or when address 0 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.

Therefore, with M306V0T-RPD-E, if address 0 is read out for anything other than interrupt processing, the yellow LED lights up as a warning. When this LED lights up, there is the possibility of illegal access to address 0, therefore check the program. This LED is extinguished from the emulator reset switch.

( 11 / 48 )

IMPORTANT

Notes on Differences between Actual MCU and Emulator:

Emulator operation differs from mask MCU operation, as listed below:

(1)Reset condition

(2)Initial values of internal resource data at power-on

(3)Internal RAM and ROM capacities, etc.

(4)Ports P00 to P57

Of the M306V0T-RPD-E's I/O ports, ports P00 - P57 are connected to the user's target system through the port emulation circuit inside M306V0T-RPD-E.

Table 1.1 gives the device which uses these ports.

Table 1.1 I/O device used by each of the ports

Port

I/O device

P00-P57 M60074-0111FP

(5)Writing into pullup control registers 0 and 1 (addresses 03FC16 and 03FD16 respectively)

To write into pullup control registers 0 and 1 (addresses 03FC16 and 03FD16 respectively), it is necessary to write the word data from address 03FC16. This is an M306V0T-RPD-E restriction.

(6)Ports P50 - P53

To enable pullup when setting bit 2 (PUR12) of the pullup register 1 to '1' in single chip mode, be sure to set the bit 2 (PM02) and bit 7 (PM07) of the processor mode register 0 to '0'. This is an M306V0T-RPD-E restriction.

(7)BCLK output disable

To disable the BCLK output, it is necessary to set the BCLK output disable bit (PM07) of processor mode register 0 (address 000416) to '1' and to set bit 3 of the port P5 direction register (address 03EB16) to '0'. This is an M306V0T-RPD-E restriction.

(8)Hold control

When an 'L' level signal is input to the terminal HOLD and the terminal enters the hold state, in actuality, ports P00 to P52 enter the hold state one half cycle later than the MCU (see Chapter 7, Operation Timing).

(9)A/D converter

A/D converter characteristics differ from actual MCU characteristics because the flexible cable and other elements are used between the emulation MCU and user’s target.

(10)Status while the program is stopped

In a system using the PC4701, the loop iteration at the address F800016 establishes and maintains the status during program stop. Also, when debug commands are issued to check or edit memory data, addresses F800016 to F83FF16 and addresses F600016 to F63FF16 are used as work area. For this reason, when the CS0 output is enabled in the microprocessor mode, the CS0 signal is output.

IMPORTANT

Notes on MAP Settings and References:

For details on MAP settings and references, refer to the M3T-PD30 emulator debugger user's manual.

Always set the SFR area to EXTERNAL.

Set the OSD RAM area to INTERNAL.

This pod uses the 4 bytes from 0FFFC16 to 0FFFF16 as a stack area for a RESET command. The RESET command cannot be correctly executed when these 4 bytes cannot be read or written to. You must therefore take care using the MAP resetting procedure when the following condition (1) or condition (2) are true.

(1)When the 4 bytes from 0FFFC16 to 0FFFF16 are set to EXTERNAL in a system shifting from single chip mode to memory expansion mode or microprocessor mode

(2)When the 4 bytes from 0FFFC16 to 0FFFF16 are set to EXTERNAL in a system started in microprocessor mode and there is no read/write-enabled memory in the external area.

Use the following MAP setting procedure when either of the above conditions (1) or (2) are true.

(1)Set the 4 bytes from bytes from 0FFFC16 to 0FFFF16 to INTERNAL.

(2)Execute the M3T-PD30 emulator debugger RESET command.

(3)Set the stack pointer. (Example)

RESET: FCLR I

LDC #480H, SP <- stack pointer setting

: (STOP the program after executing this command.)

(4)Set the 4 bytes from 0FFFC16 to 0FFFF16 to EXTERNAL.

Note on Changing Data in OSD RAM Area When Program is not Executed:

To change data when a program is not executed, write data when the map setting is in both 'INTERNAL' and 'EXTERNAL'.

Procedure

(1)With 'INTERNAL' specified, change data in the OSD RAM area. Change data in the MEMORY WINDOW, Script Window, etc.

(2)From the script window, change the map setting of the OSD RAM area to 'EXTERNAL' . MAP 400,FFF,EXT

(3)With 'EXTERNAL' specified, change data in the OSD RAM area. Change data in the MEMORY WINDOW, Script Window, etc.

(4)Change the map setting of the OSD RAM area to 'INTERNAL' again. MAP 400,FFF,INT

(Example) When changing the data in the OSD RAM area (Address: 410h) to '55h'. set MemoryByte( MB ) 410,55

MAP 400,FFF,EXT

set MemoryByte( MB ) 410,55 MAP 400,FFF,INT

IMPORTANT

Note on Reading MCU Internal Sources:

When this product is configured with the emulator debugger, the following results occur when reading the registers listed in Table 1.3. Data is not displayed correctly, but internal data is not affected at all.

(1)Real-time tracing

Data values in the MCU internal source read cycle are not displayed correctly.

(2)Real-time RAM monitoring Data is not displayed correctly.

This happens because data read from the MCU internal source is not output to an external point. When data is written into an MCU internal source, the data input from the external point is displayed correctly.
