PIN DESCRIPTIONS AND

DIAGRAMS

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 ADC, refer to the

appropriate section in this data sheet.

5.2.4.1 GP0/AN0(1)/CIN+/P1B(1)/ICSPDAT

Figure 5-1 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 ADC(1)

• an analog non-inverting input to the comparator

• a PWM output(1)

• In-Circuit Serial Programming data

5.2.4.2

GP1/AN1(1)/CIN0-/VREF(1)/ICSPCLK

Figure 5-1 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(1)

• an analog inverting input to the comparator

• a voltage reference input for the ADC(1)

• In-Circuit Serial Programming clock

Note 1: PIC12F615/617/HV615 only.
