APPENDIX B: MIGRATION FROM
PIC18F87J11 AND
PIC18F8722 TO
PIC18F87K22
Devices in the PIC18F87K22, PIC18F87J11 and
PIC18F8722 families are similar in their functions and
features. Code can be migrated from the other families
to the PIC18F87K22 without many changes. The differ-
ences between the device families are listed in
Table B-1.
