Alternate Functions of Port A
The Port A pins with alternate function are shown in
Table 10-3.
• Port A, Bit 7- ADC6/AIN0/PCINT7
• Port A, Bit 6 - ADC5/AIN1/PCINT6
• ADC6: Analog to Digital Converter, Channel 6
• AIN0: Analog Comparator Input. Configure the port pin as input with the internal pull-up
• PCINT7: Pin Change Interrupt source 8.
• ADC5: Analog to Digital Converter, Channel 5.
• AIN1: Analog Comparator Input. Configure the port pin as input with the internal pull-up
• PCINT6: Pin Change Interrupt source 6.
