The alternate pin configuration is as follows:
• Port A, Bit 7 – PCINT7/ADC7/AIN1/XREF/AREF
• Port A, Bit 6 – PCINT6/ADC6/AIN0/SS
• Port A, Bit 5 – PCINT5/ADC5/T1/USCK/SCL/SCK
• Port A, Bit 4 – PCINT4/ADC4/ICP1/DI/SDA/MOSI
• PCINT7: Pin Change Interrupt, source 7.
• ADC7: Analog to Digital Converter, channel 7.
• AIN1: Analog Comparator Positive Input. This pin is directly connected to the positive input
• XREF: Internal Voltage Reference Output. The internal voltage reference 2.56V or 1.1V is
• AREF: External Voltage Reference Input for ADC. The pin port pull-up and digital output
• PCINT6: Pin Change Interrupt, source 6.
• ADC6: Analog to Digital Converter, channel 6.
• AIN0: Analog Comparator Negative Input. This pin is directly connected to the negative
• SS: SPI Slave Select Input. When the SPI is enabled as a slave, this pin is configured as
• PCINT5: Pin Change Interrupt, source 5.
• ADC5: Analog to Digital Converter, channel 5.
• T1: Timer/Counter1 Clock Input.
• USCK: Three-wire Mode USI Clock Input.
• SCL: Two-wire Mode USI Clock Input.
• SCK: SPI Master Clock output, Slave Clock input pin. When the SPI is enabled as a slave,
• PCINT4: Pin Change Interrupt, source 4.
• ADC4: Analog to Digital Converter, channel 4.
• ICP1: Timer/Counter1 Input Capture Trigger. The PA3 pin can act as an Input Capture pin
• DI: Three-wire Mode USI Data Input. USI Three-wire mode does not override normal port
• SDA: Two-wire Mode Serial Interface (USI) Data Input / Output.

output when XREFEN is set and if either 2.56V or 1.1V is used as reference for ADC
conversion. When XREF output is enabled, the pin port pull-up and digital output driver are
turned off.

an input regardless of the setting of DDA6. As a slave, the SPI is activated when this pin is
driven low. When the SPI is enabled as a master, the data direction of this pin is controlled
by DDA6. When the pin is forced to be an input, the pull-up can still be controlled by the
PORTA6 bit.
