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 comparator. For specific
information about individual functions, refer to the
appropriate section in this data sheet.
EXAMPLE 4-3:
4.3.1
The RC0 pin is configurable to function as one of the
following:
• a general purpose I/O
• an analog input to the comparator
4.3.2
The RC1 pin is configurable to function as one of the
following:
• a general purpose I/O
• an analog input to the comparator
