| 26 | /* This file is an addendum to xc16x.cpu. Heavy use of C code isn't |
| 27 | appropriate in .cpu files, so it resides here. This especially applies |
| 28 | to assembly/disassembly where parsing/printing can be quite involved. |
| 29 | Such things aren't really part of the specification of the cpu, per se, |
| 30 | so .cpu files provide the general framework and .opc files handle the |
| 31 | nitty-gritty details as necessary. |

| 33 | Each section is delimited with start and end markers. |
