4.2.5.2
Figure 4-2 shows the diagram for this pin. The GP1 pin
is configurable to function as one of the following:
• a general purpose I/O
• an analog input for the ADC
• a analog input to the comparator
• a voltage reference input for the ADC
• In-Circuit Serial Programming clock

Figure 4-3 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 Timer0
• an external edge triggered interrupt
• a digital output from the Comparator
• a digital input/output for the CCP (refer to
