APPENDIX C:
This document is intended to describe the functional differences and the electrical specification differences that are
present when migrating from one device to the next. Table C-1 shows functional differences, while Table C-2 shows
electrical and timing differences.
TABLE C-1:
DS30605C-page 166
H/W - Issues may exist with regard to the application circuits.
S/W - Issues may exist with regard to the user program.
Prog. - Issues may exist when writing the program to the controller.

A/D
Even though compatible devices are specified to be tested to the same electrical specification, the device
characteristics may be different from each other (due to process differences). For systems that were
designed to the device specifications, these process differences should not cause any issues in the appli-
cation. For systems that did not tightly meet the electrical specifications, the process differences may cause
the device to behave differently in the application.
While there are no functional or electrical changes to the device oscillator specifications, 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.
CCP Special Event Trigger clears Timer1.
Compare mode drives pin correctly.
Writing to TMR1L does not affect TMR1H.
WDT/TMR0 prescaler assignment changes do not affect TMR0 count.
TMR2 SPI clock synchronized to start of SPI Transmission.
Can now transmit multiple words in SPI mode.
Supports all four SPI modes. (Now uses SSP vs. BSSP module.)
See SSP module in the PICmicro™ Mid-Range MCU Family Reference Man-
ual (DS33023).
