The program counter width (PCwidth) has a minor role in the assembly. It defines the width of the first column in the <file>.lst. Additionally it lets the simulator know when the program counter overruns (gore back to zero).
Example 7.1. PCwidth 16bit
0000 60 ORC RR Set RR to 1 0001 A0 IEN RR Enable inputs 0002 B0 OEN RR Enable outputs
The PCwidth can be set with the -p (--pcwidth) option or putting
OPT PCWIDTH 8
to the assembly file.
