+/* 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.
+
+ Each section is delimited with start and end markers.
