External Interrupt 3.
A falling edge on this pin will cause an external interrupt 3 if enabled.
External Interrupt 2.
A rising edge on this pin will cause an external interrupt 2 if enabled.
External Interrupt 1.
A falling edge or low level on this pin will cause an external interrupt 1 if enabled.
External Interrupt 0.
A falling edge or low level on this pin will cause an external interrupt 0 if enabled.
Serial Port Transmit.
This pin transmits the serial port data in serial port modes 1 and emits the
synchronizing clock in serial port mode 0. (Refer to ALTSEL register)
Serial Port Receive.
This pin receives the serial port data in serial port modes 1 and is a bi-directional
data transfer pin in serial port mode 0.
