4.3
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
The ANSEL and CMCON0 registers must
be initialized to configure an analog chan-
nel as a digital input. Pins configured as
analog inputs will read ‘0’.
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
