IMPORTANT
Notes on Target System:
• The Vcc pin of emulator is connected to the target system to observe the voltage of the target system.
Therefore the emulator cannot supply the power to the target system. Design your system so that
the target system is powered separately.
• The voltage of the target system should be within the range of the MCU specification and suit to
the emulator MCUs as shown below:
- For 5.0V version MCUs: +4.5 to +5.5V
• Do not change the voltage of the target system after turning on the power.
• Before powering on your emulator system, check that the host machine, the PC4701, M37900T2-
RPD-E, the converter board and target system are all connected correctly. Next, turn on the power
to each equipment following the procedure below.
(1) Turn ON/OFF the target system and the PC4701 as simultaneously as possible.
(2) When the PC4701 and emulator debugger M3T-PD79 start up, check the target status LEDs
on the emulator main unit's front panel to see if this product is ready to operate.
• Is the power supplied? Check that target status LED (POWER) is ON.
• Is the clock supplied? Check that target status LED (CLOCK) is ON.
Note on Reset Input from the Target System:
• 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).
Notes on Stack Area:
• With this product, a maximum 26 bytes of the user stack is consumed as work area.
• If the user stack does not have enough area, do not use areas which cannot be used as stack (SFR
area, RAM area which stores data, or ROM area) as work area. Using areas like this is a cause of
user program crashes and destabilized emulator control. Therefore, ensure the +26 byte maximum
capacity used by the user program as the user stack area.
Note on MCU Files:
• When starting up the emulator debugger M3T-PD79, select the MCU file corresponding to the
MCU which is going to be debugged by Init dialog (MCU files are included with the emulator
debugger M3T-PD79).
