3.3
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.
3.3.1
Figure 3-1 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 (PIC12F675 only)
• an analog input to the comparator
3.3.2
Figure 3-1 shows the diagram for this pin. The GP1 pin
is configurable to function as one of the following:
• as a general purpose I/O
• an analog input for the A/D (PIC12F675 only)
• an analog input to the comparator
• a voltage reference input for the A/D (PIC12F675
