To each peripheral function

• WICR register (interrupt pin selection circuit control register)

This register is used to determine which of the available peripheral input pins should be outputted to the

interrupt circuit and which interrupt pins they should serve as.

• Selection circuit

This circuit outputs the input from the pin selected by the WICR register to the INT00 input of the

external interrupt circuit (channel 0).
