• ADC5/ACMP2/INT1/SCK – Bit 5
ADC5, Analog to Digital Converter, input channel 5
ACMP2, Analog Comparator 2 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.
INT1, External Interrupt source 1. This pin can serve as an external interrupt source to the MCU.
SCK: Master Clock output, Slave Clock input pin for SPI channel. When the SPI is enabled as a slave, this
pin is configured as an input regardless of the setting of DDD4. When the SPI is enabled as a master, the
data direction of this pin is controlled by DDD4. When the pin is forced to be an input, the pull-up can still
be controlled by the PORT bit.
• MOSI/ADC3/ACMPM– Bit 4
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.
ADC3, Analog to Digital Converter, input channel 3.
ACMPM, Analog Comparators 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.
• PSCOUTR1/ADC2/ACMP2M– Bit 3
PSCOUTR1: Output 1 of PSCR.
ADC2, Analog to Digital Converter, input channel 2
ACMP2M, Analog Comparator 2 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.
• INT0/PSCOUT21 – Bit 2
INT0, External Interrupt source 0. This pin can serve as an external interrupt source to the MCU.
PSCOUT21: Output 1 of PSC 2.
• PSCOUT20 – Bit 1
PSCOUT20: Output 0 of PSC 2.
• T1/PSCOUT23/ACMP3_OUT – Bit 0
T1, Timer/Counter1 counter source.
PSCOUT23: Output 3 of PSC 2.
ACMP3_OUT, Analog Comparator3 Output.
