3.5.1 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 individual functions

such as the LCD or SSP, refer to the appropriate section

in this data sheet.

3.5.1.1 RC0/VLCD1

Figure 3-14 shows the diagram for this pin. The RC0

pin is configurable to function as one of the following:

• a general purpose I/O

• an analog input for the LCD bias voltage

3.5.1.2 RC1/VLCD2

Figure 3-15 shows the diagram for this pin. The RC1

pin is configurable to function as one of the following:

• a general purpose I/O

• an analog input for the LCD bias voltage

3.5.1.3 RC2/VLCD3

Figure 3-16 shows the diagram for this pin. The RC2

pin is configurable to function as one of the following:

• a general purpose I/O

• an analog input for the LCD bias voltage
