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
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.
