7647G–AVR–09/11
• PCINT0/MISO/PSCOUT2A – Bit 0
MISO, Master Data input, Slave Data output pin for SPI channel. When the SPI is enabled as
a master, this pin is configured as an input regardless of the setting of DDB0. When the SPI is
enabled as a slave, the data direction of this pin is controlled by DDB0. When the pin is forced
to be an input, the pull-up can still be controlled by the PORTB0 and PUD bits.
PSCOUT2A, Output 2A of PSC.
PCINT0, Pin Change Interrupt 0.
