PIC12F609/615/12HV609/615
4.2.4.3
Figure 4-2 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 ADC
• the clock input for TMR0
• an external edge triggered interrupt
• a digital output from Comparator
• a Capture input/Compare input/PWM output
• a PWM output
