• ADC6/INT2/ACMPN1/AMP2-/PCINT5 – Bit 5
ADC6, Analog to Digital Converter, input channel 6.
INT2, External Interrupt source 2. This pin can serve as an External Interrupt source to the MCU.
ACMPN1, Analog Comparator 1 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 Ana-
log Comparator.
PCINT5, Pin Change Interrupt 5.
• APM0+/PCINT4 – Bit 4
AMP0+, Analog Differential Amplifier 0 Positive Input Channel.
PCINT4, Pin Change Interrupt 4.
• AMP0-/PCINT3 – Bit 3
AMP0-, Analog Differential Amplifier 0 Negative Input Channel. 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 Amplifier.
PCINT3, Pin Change Interrupt 3.
• ADC5/INT1/ACMPN0/PCINT2 – Bit 2
ADC5, Analog to Digital Converter, input channel 5.
INT1, External Interrupt source 1. This pin can serve as an external interrupt source to the MCU.
ACMPN0, Analog Comparator 0 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 Ana-
log Comparator.
PCINT2, Pin Change Interrupt 2.
• PCINT1/MOSI/PSCOUT2B – Bit 1
MOSI: SPI Master Data output, Slave Data input for SPI channel. When the SPI is enabled as a
slave, this pin is configured as an input regardless of the setting of DDB1 When the SPI is
enabled as a master, the data direction of this pin is controlled by DDB1. When the pin is forced
to be an input, the pull-up can still be controlled by the PORTB1 and PUD bits.
PSCOUT2B, Output 2B of PSC.
PCINT1, Pin Change Interrupt 1.
• PCINT0/MISO/PSCOUT2A – Bit 0
MISO, Master Data input, Slave Data output pin for SPI channel. When the SPI is enabled as a
master, this pin is configured as an input regardless of the setting of DDB0. When the SPI is
enabled as a slave, the data direction of this pin is controlled by DDB0. When the pin is forced to
be an input, the pull-up can still be controlled by the PORTB0 and PUD bits.
PSCOUT2A, Output 2A of PSC.
PCINT0, Pin Change Interrupt 0.
