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 Enhanced CCP or the A/D, refer to the
appropriate section in this data sheet.
EXAMPLE 4-3:
4.3.1
The RC0 is configurable to function as one of the
following:
• a general purpose I/O
• an analog input for the A/D Converter
• an analog input to the comparator
4.3.2
The RC1 is configurable to function as one of the
following:
• a general purpose I/O
• an analog input for the A/D Converter
• an analog input to the comparator

STATUS,RP0
The ANSEL (91h) and CMCON0 (19h)
registers must be initialized to configure
an analog channel as a digital input. Pins
configured as analog inputs will read ‘0’.
