Table 10-3. Port A Pins Alternate Functions
Port A, Bit 0 – ADC0/PCINT0
ADC0: Analog to Digital Converter, Channel 0.
PCINT0: Pin Change Interrupt source 0. The PA0 pin can serve as an external interrupt source for pin
change interrupt 0.
Port A, Bit 1 – ADC1/AIN0/PCINT1
ADC1: Analog to Digital Converter, Channel 1.
AIN0: Analog Comparator Positive 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.
PCINT1: Pin Change Interrupt source 1. The PA1 pin can serve as an external interrupt source for pin
change interrupt 0.
Port A, Bit 2 – ADC2/AIN1/PCINT2
ADC2: Analog to Digital Converter, Channel 2.
AIN1: Analog Comparator Negative 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.
