4.5 The PIC14 port

The PIC14 port adds support for Microchip PIC MCUs with 14 bit wide instructions. This port is not yet mature and still lacks many features. However, it can work for simple code.

Currently supported devices include:

12F: 629, 635, 675, 683

16C: 432, 433

16C: 554, 557, 558

16C: 62, 620, 620a, 621, 621a, 622, 622a, 63a, 65b

16C: 71, 710, 711, 715, 717, 72, 73b, 745, 74b, 765, 770, 771, 773, 774, 781, 782

16C: 925, 926

16CR: 620a, 73, 74, 76, 77

16F: 616, 627, 627a, 628, 628a, 630, 636, 639, 648, 648a, 676, 684, 685, 687, 688, 689, 690

16F: 716, 72, 73, 737, 74, 747, 76, 767, 77, 777, 785

16F: 818, 819, 84, 84a, 87, 870, 871, 872, 873, 873a, 874, 874a, 876, 876a, 877, 877a, 88, 886, 887

16F: 913, 914, 916, 917, 946

26HV: 626, 785

An up-to-date list of currently supported devices can be obtained via `sdcc -mpic14 -phelp foo.c` (foo.c must exist...).
