IMPORTANT

Notes on EMEM Dialog:

• When setting the EMEM dialog box of emulator debugger M3T-PD79, pay attention to the

following:

(1) Processor Mode

Specify a processor mode for the target MCU to be debugged. With 7905 Group MCUs, only

the single-chip mode is specifiable. If the MD0 pin setting is not "L" level, emulator debugger

M3T-PD79 outputs an error message. In such a case, check the pin settings on the target

system.

(2) Emem Address

Allocate the 1MB emulation memory that is included in the emulation pod. For the 7905

Group, it is not necessary to set this because this group operates only in the single-chip mode.

(3) ROM Address

Disable the allocated emulation memory against writes by the user program. For the 7905

Group, it is not necessary to set this because this group operates only in the single-chip mode.

(4) DMA Address

In this dialog box, set a transfer area when using the MCU's DMA function, and executing 1-

bus transfer between emulation memory and the target system. For the 7905 Group, do not set

such areas because this group does not have the DMA function.

(5) 8-bit bus mode Address

When accessing external data buses in 8-bit width using the chip select wait controller when

BYTE pin = Low, set this address for the relevant area. For the 7905 Group, it is not necessary

to set this because this group operates only in the single-chip mode.

(6) Map Address

Set external or internal for the allocated emulation memory area. For the 7905 Group, it is not

necessary to set this because this group operates only in the single-chip mode.

Note on Boot Mode:

• It is not possible to debug the MCUs in the boot mode using this emulator system.

(The MD1 pin of the MCU is fixed to the "L" level.)

Note on Breaks Used with Internal Resources:

• Hardware breaks cannot be used with internal resources (SFR, RAM and flash ROM) when using

emulator PC4701L.

Note on Software Breaks:

• Do not use software breaks when operating with a clock frequency of 1 MHz or less. This is the

unavoidable limitation imposed for reason of MCU and emulator specifications. In this case, make

use of chip breaks or hardware breaks (PC4701M and PC4701HS only).

Note on Debug Monitor Area:

• The debug monitor area is fixed to the "FF" bank. It cannot be set to other banks.
