PORTC is a general purpose I/O port consisting of 6
bidirectional pins. The pins can be configured for either
digital I/O or analog input to comparator. For specific
information about individual functions, refer to the
appropriate section in this data sheet.

PORTC
The CMCON0 register must be initialized
to configure an analog channel as a digital
input. Pins configured as analog inputs will
read ‘0’.
Unimplemented: Read as ‘0’
RC<5:0>: PORTC General Purpose I/O Pin bits
1 = Port pin is > V
0 = Port pin is < V
Unimplemented: Read as ‘0’
TRISC<5:0>: PORTC Tri-State Control bits
