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
