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 A/D Converter (ADC) or
Comparator. For specific information about individual
functions such as the Enhanced CCP or the ADC, refer
to the appropriate section in this data sheet.

PORTC and the TRISC Registers
The ANSEL register must be initialized to
configure an analog channel as a digital
input. Pins configured as analog inputs will
read ‘0’ and cannot generate an interrupt.
Unimplemented: Read as ‘0’
RC<5:0>: PORTC I/O Pin bit
1 = PORTC pin is > V
0 = PORTC pin is < V
Unimplemented: Read as ‘0’
TRISC<5:0>: PORTC Tri-State Control bit
1 = PORTC pin configured as an input (tri-stated)
0 = PORTC pin configured as an output
