Atmel ATtiny24/44/84 [Preliminary]
Alternate Functions of Port A
The Port A pins with alternate function are shown in
Table 12-3.
• Port A, Bit 0 – ADC0/AREF/PCINT0
ADC0: Analog to Digital Converter, Channel 0
AREF: External Analog Reference for ADC. Pullup and output driver are disabled on PA0
when the pin is used as an external reference or Internal Voltage Reference with external
capacitor at the AREF pin by setting (one) the bit REFS0 in the ADC Multiplexer Selection
Register (ADMUX).
PCINT0: Pin Change Interrupt source 0. The PA0 pin can serve as an external interrupt
source for pin change interrupt 0.
