7701E–AVR–02/11
• Port A, Bit 1 – ADC1/AIN0/PCINT1
ADC1: Analog to Digital Converter, Channel 1
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.
PCINT1: Pin Change Interrupt source 1. The PA1 pin can serve as an external interrupt
source for pin change interrupt 0.
• Port A, Bit 2 – ADC2/AIN1/PCINT2
ADC2: Analog to Digital Converter, Channel 2
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.
PCINT2: Pin Change Interrupt source 2. The PA2 pin can serve as an external interrupt
source for pin change interrupt 0.
• Port A, Bit 3 – ADC3/T0/PCINT3
ADC3: Analog to digital converter, channel 3.
T0: Timer/counter 0 counter source.
PCINT3: Pin change interrupt source 3. The PA3 pin can serve as an external interrupt source
for pin change interrupt 0.
• Port A, Bit 4 – ADC4/USCK/SCL/T1/PCINT4
ADC4: Analog to Digital Converter, Channel 4
USCK: Three-wire mode Universal Serial Interface Clock.
SCL: Two-wire mode Serial Clock for USI Two-wire mode.
T1: Timer/Counter1 counter source.
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 – ADC5/DO/OC1B/PCINT5
ADC5: Analog to digital converter, channel 5.
DO: Data output in USI three-wire mode. Data output (DO) overrides PORTA5 value, and it is
driven to the port when the data direction bit DDA5 is set (one). However the PORTA5 bit still
controls the pull-up, enabling pull-up if direction is input and PORTA5 is set (one).
OC1B: Output compare match output: The PA5 pin can serve as an external output for the
Timer/Counter1 compare match B. The PA5 pin has to be configured as an output (DDA5 set
(one)) to serve this function. The OC1B pin is also the output pin for the PWM mode timer
function.
PCINT5: Pin change interrupt source 5. The PA5 pin can serve as an external interrupt source
for pin change interrupt 0.
