Alternate Functions of Port A
The Port A pins with alternate functions are shown in
Table 10-3.
The alternate pin configuration is as follows:
• PCINT27 – Port A, Bit 3
PCINT27: Pin Change Interrupt source 27.
• PCINT26 – Port A, Bit 2
PCINT26: Pin Change Interrupt source 26.
• ADC7/PCINT25 – Port A, Bit 1
ADC7: PA1 can be used as ADC input Channel 7.
PCINT25: Pin Change Interrupt source 25.
• ADC6/PCINT24 – Port A, Bit 0
ADC6: PA0 can be used as ADC input Channel 6.
PCINT24: Pin Change Interrupt source 24.
