PIC16F630/676
3.3
PORTC is a general purpose I/O port consisting of 6 bi-
directional pins. The pins can be configured for either
digital I/O or analog input to A/D converter. For specific
information about individual functions such as the
comparator or the A/D, refer to the appropriate section
in this Data Sheet.
EXAMPLE 3-2:
3.3.1
The RC0/RC1/RC2/RC3 pins are configurable to
function as one of the following:
• a general purpose I/O
• an analog input for the A/D Converter

The ANSEL register (91h) must be clear to
configure an analog channel as a digital
input. Pins configured as analog inputs will
read ‘0’. The ANSEL register is defined for
the PIC16F676.
