Q.
I invoke the PD30 emulator debugger and input "MAP 4000H, 027FFFh, EXTERNAL" in the SCRIPT WINDOW for the CS2
setup. Then, when I execute the "Go" command, my program malfunctions.
A.
The M16C/60 Series emulation pod uses 4 bytes of the emulation MCU stack (0FFFCh to 0FFFFh) after the "Reset" command is
executed. When the memory location including this area is assigned in the external space by the "MAP" command and there is no
RAM placed in the target system, the emulation MCU will not be able to set up the stack there. In this situation, if the "GO"
command is executed, the emulation MCU executes the program from the wrong PC address. That is why your program
malfunctions.
To avoid this problem in M30620T/TB-RPD-E, please carefully review page 15 of the instruction manual. For other emulation
pods, please review Section 1 of the instruction manual, "Precautions for Safety".
