driven low. When the SPI is enabled as a master, the data direction of this pin is controlled by
DDD0. When the pin is forced to be an input, the pull-up can still be controlled by the
PORTD0 bit.
– PCINT9, Pin Change Interrupt 9.
• PCINT8/PSCOUT1A/INT3 – Bit 0
– PSCOUT1A, Output 1A of PSC.
– INT3, External Interrupt source 3: This pin can serve as an external interrupt source to the
MCU.
– PCINT8, Pin Change Interrupt 8.
