Note on HOLD* Input:
•Be sure to input "L" to the HOLD* pin of the target system during the user program executing.
Inputting "L" to the HOLD pin when stopping the user program or when run-time debugging may
cause a malfunction of the emulator.
Note on Software Reset:
• Do not use a software reset.
Note on Protect Resistor (PRC2):
•Make note of the fact that the protect is not canceled when protect register (PRC2), which enables
writing in the port P9 direction register and the SI/O3, 4 control register, is changed with the below
procedure.
(1) Step execution of the "instruction for setting ("1") PRC2"
(2) Setting the break point from the "instruction for setting ("1") PRC2" to when the "setting the
register for the protect"
(3) Setting "("1") PRC2" from the dump window or script window
Note on Pullup Control Resistor:
• Ports P0
0
to P5
7
are not pulled up by the pullup control resistor.
When pulling up the ports P0
0
to P5
7
, apply a resistance to the inside of the emulator. How to apply
it, refer to "3.2 Setting Switches and Pullup Resistor" (page 25).
Note: Ports P6
0
to P10
0
are pulled up by the pullup control resistor.
Note: Pullup control resistor can read and write from P0
0
to P10
0
properly.
IMPORTANT
Note 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).
Notes on Address Match Interrupt:
• Do not set software breaks at the same addresses as address-match interrupts as the program may
run out of control.
• Do not set a hardware break within 4 instructions before an address at which an address-match
interrupt occurs. If you do set a hardware break in this range, the program will run out of control.
•When an address at which an address-match interrupt occurs is executed in one-step mode, the
program stops after executing the first instruction after returning from the address-match interrupt
processing.
