IMPORTANT
Notes on Connecting Target System:
• When connecting the FLX100 flexible cable and the converter board, be careful not to forcibly
press the connector top of the converter board. (The flexible cable and the converter board are
guaranteed for only 20 insertion/removal iterations.)
• Especially be careful not to insert the converter board in the wrong direction.
Note on Reset Input from Target System:
• The reset input from the target system is accepted only during program execution (while the RUN
signal lamp on the PC4701 is lit).
Note on HOLD Input from Target System:
• Input an 'L' level signal into the HOLD pin only during program execution. Doing so while the
program is stopped or during run time debugging may cause the emulator to malfunction.
Note on Address 0 Access:
• With M16C/6V group MCUs, when a maskable interrupt is generated, the interrupt data (interrupt
number and interrupt request level) stored in address 0 is read out.
Also, the interrupt request bit is cleared when address 0 is read out. Consequently, when the address
0 readout instruction is executed or when address 0 is read out in the cause of a program runaway,
a malfunction occurs in that the interrupt is not executed despite the interrupt request, because the
request bit of the highest priority interrupt factor enabled is cleared.
Therefore, with M306V0T-RPD-E, if address 0 is read out for anything other than interrupt
processing, the yellow LED lights up as a warning. When this LED lights up, there is the possibility
of illegal access to address 0, therefore check the program. This LED is extinguished from the
emulator reset switch.
