1477K–AVR–08/10
AIN0: Analog Comparator Positive input and ADC5: ADC input channel 5
as input with the internal pull-up switched off to avoid the digital port function from interfering
with the function of the Analog Comparator or analog to digital converter.
PCINT1: Pin Change Interrupt 1 pin. Pin change interrupt is enabled on pin when global interrupt
is enabled, pin change interrupt is enabled and the alternate function do not mask the interrupt.
The masking alternate function is the Analog Comparator. Digital input is enabled on pin PA6
also in SLEEP modes, if the pin change interrupt is enabled and not masked by the alternate
function.
• ADC4, ADC3 Port – A, Bit 5, 4
ADC4/ADC3: ADC Input Channel 4 and 3. Configure the port pins as inputs with the internal
pull-ups switched off to avoid the digital port function from interfering with the function of the ana-
log to digital converter.
• AREF/PCINT1 Port – A, Bit 3
AREF: External Reference for ADC. Pullup and output driver are disabled on PA3 when the pin
is used as an external reference or Internal Voltage Reference (2.56V) with external capacitor at
the AREF pin by setting (one) the bit REFS0 in the ADC Multiplexer Selection Register
(ADMUX).
PCINT1: Pin Change Interrupt 1 pin. Pin change interrupt is enabled on pin when global interrupt
is enabled, pin change interrupt is enabled and the alternate function do not mask the interrupt.
The masking alternate function is the pin usage as an analog reference for the ADC. Digital input
is enabled on pin PA3 also in SLEEP modes, if the pin change interrupt is enabled and not
masked by the alternate function.
