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 of
XREF: Internal Voltage Reference Output. The internal voltage reference 2.56V or 1.1V is out-

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 input
SS: SPI Slave Select Input. When the SPI is enabled as a slave, this pin is configured as an

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, this

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