ATmega16M1/32M1/64M1
SS_A: Slave Port Select input. When the SPI is enabled as a slave, this pin is configured as an
input regardless of the setting of DDD0. As a slave, the SPI is activated when this pin is 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.
