Table 13-3.
The alternate pin configuration is as follows:
• ADC4/PSCOUT0B/SCK/PCINT7 – Bit 7
PSCOUT0B, Output 0B of PSC.
ADC4, Analog to Digital Converter, input channel 4.
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 DDB7. When the SPI is
enabled as a master, the data direction of this pin is controlled by DDB7. When the pin is forced
to be an input, the pull-up can still be controlled by the PORTB7 bit.
PCINT7, Pin Change Interrupt 7.
• ADC7/PSCOUT1B/PCINT6 – Bit 6
ADC7, Analog to Digital Converter, input channel 7.
PSCOUT1B, Output 1B of PSC.
PCINT6, Pin Change Interrupt 6.
