PORTC PIN DESCRIPTIONS AND
DIAGRAMS
Each PORTC pin is multiplexed with other functions.
The pins and their combined functions are briefly
described here. For specific information about individ-
ual functions such as the comparator or the A/D, refer
to the appropriate section in this Data Sheet.
4.4.1.1
RC0/AN4/C2IN+
The RC0 is configurable to function as one of the
following:
a general purpose I/O
an analog input for the A/D Converter
the non-inverting input to comparator 2
4.4.1.2
RC6/AN8/OP1-
The RC6/AN8/OP1- pin is configurable to function as
one of the following:
a general purpose I/O
an analog input for the A/D
the inverting input for Op Amp 1
4.4.1.3
RC7/AN9/OP1+
The RC7/AN9/OP1+ pin is configurable to function as
one of the following:
a general purpose I/O
an analog input for the A/D
the non-inverting input for Op Amp 1

4.4.1.4
RC1/AN5/C12IN1-/PH1
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 comparators 1 & 2
a digital output from the Two-Phase PWM
