Alternate Functions of Port D
The Port D pins with alternate functions are shown in
Table 10-11. Port D Pins Alternate Functions
The alternate pin configuration is as follows:
• AIN1/PCINT23 – Port D, Bit 7
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.
PCINT23: Pin Change Interrupt source 23. The PD7 pin can serve as an external interrupt
source.
• AIN0/PCINT22 – Port D, Bit 6
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.
PCINT22: Pin Change Interrupt source 22. The PD6 pin can serve as an external interrupt
source.
• T1/PCINT21 – Port D, Bit 5
T1: Timer/Counter1 counter source.
PCINT21: Pin Change Interrupt source 21. The PD5 pin can serve as an external interrupt
source.
• T0/PCINT20 – Port D, Bit 4
T0: Timer/Counter0 counter source.
PCINT20: Pin Change Interrupt source 20. The PD4 pin can serve as an external interrupt
source.
