+/* 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.
