I didnt get to test the debugger mode of ICD2 using your recommendation coz my proto board was not working well maybe need to recheck the connections.

But anyway...I just observed the format on how the 876 & 877 series ICDDEFS code vs the Program/data memory used was coded..see below.

Any thought about this why? I understand the "reserving 12 bytes of RAM from 0x1F4-0x1FF" on the PIC18F2550 series" but this one seems different.
Am I correct that it is 11bytes of ram was reserved? Why it is written "ICDRESERVED1 & ICDRESERVED11".

Just some curiosity Bruce hope you can answer my questions in here still.

Thanks in Advance

Chris
