APPENDIX B: MIGRATING FROM
OTHER PIC^®
DEVICES
This discusses some of the issues in migrating from
other PIC^® devices to the PIC16F722A/723A family of
devices.
Note:
This device has been designed to perform
to the parameters of its data sheet. It has
been tested to an electrical specification
designed to determine its conformance
with these parameters. Due to process
differences in the manufacture of this
device, this device may have different
performance characteristics than its
earlier version. These differences may
cause this device to perform differently in
your application than the earlier version of
this device.
Note:
The user should verify that the device
oscillator starts and performs as
expected. Adjusting the loading capacitor
values and/or the oscillator mode may be
required.
