ATtiny261/ATtiny461/ATtiny861
• Port A, Bit 6 - ADC5/AIN1/PCINT6
ADC5: Analog to Digital Converter, Channel 5.
AIN1: Analog Comparator 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.
PCINT6: Pin Change Interrupt source 6.
• Port A, Bit 5 - ADC4/AIN2/PCINT5
ADC4: Analog to Digital Converter, Channel 4.
AIN2: Analog Comparator 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.
• Port A, Bit 4 - ADC3/ICP0/PCINT4
ADC3: Analog to Digital Converter, Channel 3.
ICP0: Timer/Counter0 Input Capture Pin.
PCINT4: Pin Change Interrupt source 4.
• Port A, Bit 3 - AREF/PCINT3
AREF: External analog reference for ADC. Pull-up and output driver are disabled on PA3 when
the pin is used as an external reference or internal voltage reference with external capacitor at
the AREF pin.
PCINT3: Pin Change Interrupt source 3.
• Port A, Bit 2 - ADC2/INT1/USCK/SCL/PCINT2
ADC2: Analog to Digital Converter, Channel 2.
INT1: The PA2 pin can serve as an External Interrupt source 1.
USCK: Three-wire mode Universal Serial Interface Clock.
SCL: Two-wire mode Serial Clock for USI Two-wire mode.
PCINT2: Pin Change Interrupt source 2.
• Port A, Bit 1 - ADC1/DO/PCINT1
ADC1: Analog to Digital Converter, Channel 1.
DO: Three-wire mode Universal Serial Interface Data output. Three-wire mode Data output over-
rides PORTA1 value and it is driven to the port when data direction bit DDA1 is set. PORTA1 still
enables the pull-up, if the direction is input and PORTA1 is set.
PCINT1: Pin Change Interrupt source 1.
• Port A, Bit 0 - ADC0/DI/SDA/PCINT0
ADC0: Analog to Digital Converter, Channel 0.
