I've been working with the code for my PIC16C54 project on the MPSIM
simulator from MicroChip. As soon as I ussue the GO command there's
a warning that uninitialized code at 01FF has been executed and then
everything else runs as I'd expect it to do. The manual says the '54's
PC defaults to 1F on power up. If I try to put something in that location
like many of the MicroChip BBS examples I get an assembler warning.
What's going on? Is this an assembler or simulator bug? Should I ignore
the MPSIM warning?
