• WICR register (interrupt pin selection circuit control register)
This register is used to determine which of the available peripheral input pins should be
output 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 (ch. 0).
