4.3.3

RC2/AN6/P1D

The RC2 is configurable to function as one of the

following:

• a general purpose I/O

• an analog input for the A/D Converter

• a digital output from the Enhanced CCP

4.3.4

RC3/AN7/P1C

The RC3 is configurable to function as one of the

following:

• a general purpose I/O

• an analog input for the A/D Converter

• a digital output from the Enhanced CCP

4.3.5

RC4/C2OUT/P1B

The RC4 is configurable to function as one of the

following:

• a general purpose I/O

• a digital output from the comparator

• a digital output from the Enhanced CCP

Enable

Note

Analog Input mode comes from ANSEL.

Note:

Enabling both C2OUT and P1B will cause

a conflict on RC4 and create unpredictable

results. Therefore, if C2OUT is enabled,

the ECCP can not be used in Half-bridge

or Full-bridge mode and vise-versa.
