IMPORTANT
Note on RDY* Input:
•Be sure to input "L" to the RDY* pin of the target system during the user program executing (only
while the RUN status LED on the PC4701's front panel is lit). Inputting "L" to the RDY* pin during
the user program stopping may cause a malfunction of the emulator.
Note on HOLD* Input:
• Be sure to input "L" to the HOLD* pin of the target system during the user program executing (only
while the RUN status LED on the PC4701's front panel is lit). Inputting "L" to the HOLD* pin
during the user program stopping may cause a malfunction of the emulator.
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 Interruption:
• Even while the user program is not being executed (when the user program is paused or while debug
programs are running), the evaluation MCU is operating for controlling debug programs.
Therefore, take note that timers and other functions are not stopped while the user program is not
being executed.
• When a maskable interrupt is generated in user program execution (when the user program is
paused or while debug programs are running), the interrupt cannot be accepted, because the
emulator disables interrupts. If an interrupt is requested while a user program is not being executed
and the user program allow the interrupt, the interrupt is accepted immediately after the user
program execution is started.
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.
Notes on Access Prohibited Area:
• The emulator control register (000020h - 00003Fh) in the SFR is read and write-protected. When
this register is accessed, emulator control cannot be utilized.
•With this product, address FFFFFFh cannot be read or written in correctly.
