APPENDIX E:
A detailed discussion of the differences between the
mid-range MCU devices (i.e., PIC16CXXX) and the
Enhanced devices (i.e., PIC18FXXX) is provided in
AN716, “Migrating Designs from PIC16C74A/74B to
PIC18C442”. The changes discussed, while device
specific, are generally applicable to all mid-range to
Enhanced device migrations.
This Application Note is available as Literature Number
DS00716.
