APPENDIX C: WHAT’S NEW

The structure of the document has been made consis-

tent with other data sheets. This ensures that important

topics are covered across all PIC16/17 families. Here is

an overview of new features.

Added the following devices:

PIC17CR42

PIC17C42A

PIC17CR43

A 33 MHz option is now available.

APPENDIX D: WHAT’S CHANGED

To make software more portable across the different

PIC16/17 families, the name of several registers and

control bits have been changed. This allows control bits

that have the same function, to have the same name

(regardless of processor family). Care must still be

taken, since they may not be at the same special func-

tion register address. The following shows the register

and bit names that have been changed:

Instruction DECFSNZ corrected to DCFSNZ

Instruction INCFSNZ corrected to INFSNZ

Enhanced discussion on PWM to include equation for

determining bits of PWM resolution.

Section 13.2.2 and 13.3.2 have had the description of

updating the FERR and RX9 bits enhanced.

The location of conﬁguration bit PM2 was changed

(Figure 6-1 and Figure 14-1).

Enhanced description of the operation of the INTSTA

Added note to discussion of interrupt operation.

Tightened electrical spec D110.

Corrected steps for setting up USART Asynchronous

Reception.
