4.2.4
Each GPIO 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 comparator or the A/D, refer to the
appropriate section in this data sheet.
4.2.4.1
Figure 4-1 shows the diagram for this pin. The GP0 pin
is configurable to function as one of the following:
• a general purpose I/O
• an analog input for the A/D
• an analog input to the comparator
• an analog input to the Ultra Low-Power Wake-up
• In-Circuit Serial Programming data
