Alternate Functions of Port A
Table 12-5.
Note:
The Port A pins with alternate function are shown in
Table 12-6.
The alternate pin configuration is as follows:
• Port A, Bit 7- ADC6/AIN0/PCINT7
ADC6: Analog to Digital Converter, Channel 6
AIN0: Analog Comparator Input. Configure the port pin as input with the internal pull-up switched
off to avoid the digital port function from interfering with the function of the Analog Comparator.
PCINT7: Pin Change Interrupt source 8.
