PIC12F629/675

3.3.3

GP2/AN2/T0CKI/INT/COUT

Figure 3-2 shows the diagram for this pin. The GP2 pin

is configurable to function as one of the following:

• a general purpose I/O

• an analog input for the A/D (PIC12F675 only)

• the clock input for TMR0

• an external edge triggered interrupt

• a digital output from the comparator
