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:
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.
• a general purpose I/O
• an analog input for the LCD bias voltage
