IMPORTANT

Note on RESET* Input:

•The RESET* input from the target system is accepted only while a user program is being executed

(only while the RUN status LED on the PC4701's front panel is lit).

Note on Clock Supply to the MCU:

•Clock can be supplied to the evaluation MCU in one of the following two ways. This is determined

by emulator debugger clock selection.

(1) When Internal is selected:

The clock generated by the oscillation circuit in the emulation pod is supplied to the evaluation

MCU. The clock is continually supplied to the evaluation MCU regardless of "target system

clock status" and "user program execution status".

(2) When External is selected:

Clock supply to the evaluation MCU depends on oscillation status (oscillate/off) of the target

system.

Note on HOLD* Input:

•Be sure to input "L" to the HOLD* pin of the target system during the user program execution (while

the RUN status LED on the PC4701's front panel is lit). Inputting "L" to the HOLD* pin when

stopping the user program may cause a malfunction of the emulator.

Notes on NMI* Input:

•NMI* input from the target system is accepted only while a user program is being executed (only

while the RUN status LED on the PC4701's front panel is lit).

•NMI* interrupts are generated in the following situations.

(1) Immediately after the NMI* pin changes from "H" to "L" level during the target program

execution

(2) After a reset is released by the target system when the NMI* pin is "L" level during the target

program execution

(3) Immediately after program execution starts with the NMI* pin "L" level, following the reset

input from the emulator debugger or emulator main unit

(4) Immediately after program execution starts when the NMI* pin is "H" level immediately

before the target program stops and changes to "L" level when target program execution starts

Note on RDY* Input:

•Be sure to input "L" to the RDY* pin of the target system during the user program execution (while

the RUN status LED on the PC4701's front panel is lit). Inputting "L" to the RDY* pin when

stopping the user program may cause a malfunction of the emulator.
