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 or compara-
tor. For specific information about individual functions
such as the EUSART or the A/D converter, refer to the
appropriate section in this data sheet.

PORTC
The ANSEL and CMCON0 registers 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 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 bits
1 = PORTC pin configured as an input (tri-stated)
0 = PORTC pin configured as an output
