6.1.4
Each PORTA 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 A/D Converter (ADC), refer to the
appropriate section in this data sheet.

configurable to function as one of the following:
• a general purpose I/O
• an analog input for the ADC
• external interrupt
• clock input for Timer0
The Timer0 clock input function works independently of
any TRIS register setting. Effectively, if TRISA2 = 0,
the PORTA2 register bit will output to the pad and Clock
Timer0 at the same time.
