Port A, Bit 4 – AIN0/PCINT4
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.
PCINT4: Pin Change Interrupt source 4. The PA4 pin can serve as an external interrupt source
for pin change interrupt 0.
Port A, Bit 5 – AIN1/PCINT5
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.
PCINT5: Pin Change Interrupt source 5. The PA5 pin can serve as an external interrupt source
for pin change interrupt 0.
Port A, Bit 6 – CLKI/PCINT6
CLKI: External Clock Input. When used as a clock pin, the pin can not be used as an I/O pin.
PCINT6: Pin Change Interrupt source 6. The PA6 pin can serve as an external interrupt source
for pin change interrupt 0.
Port A, Bit 7 – RESET/dW/PCINT7
RESET: External Reset input is active low and enabled by unprogramming (“1”) the RSTDISBL
Fuse. Pullup is activated and output driver and digital input are deactivated when the pin is used
as the RESET pin.
dW: When the debugWIRE Enable (DWEN) Fuse is programmed and Lock bits are unpro-
grammed, the debugWIRE system within the target device is activated. The RESET port pin is
configured as a wire-AND (open-drain) bi-directional I/O pin with pull-up enabled and becomes
the communication gateway between target and emulator.
PCINT7: Pin Change Interrupt source 7. The PA7 pin can serve as an external interrupt source
for pin change interrupt 0.
