4.4.1 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:

• General purpose I/O

• Analog input for the A/D Converter

• 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:

• General purpose I/O

• Analog input for the A/D

• 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:

• General purpose I/O

• Analog input for the A/D

• Non-inverting input for Op Amp 1
