/* This file is an addendum to xc16x.cpu. Heavy use of C code isn't
|
||
appropriate in .cpu files, so it resides here. This especially applies
|
||
to assembly/disassembly where parsing/printing can be quite involved.
|
||
Such things aren't really part of the specification of the cpu, per se,
|
||
so .cpu files provide the general framework and .opc files handle the
|
||
nitty-gritty details as necessary.
