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.
