Overview of Interrupt Pin Selection Circuit

The interrupt pin selection circuit selects pins to be used as interrupt input pins from
among various peripheral input pins.
Interrupt Pin Selection Circuit
The interrupt pin selection circuit is used to select interrupt input pins from amongst various peripheral
inputs (TRG0/ADTG, UCK0, UI0, EC0, SCK, SI, INT00). The input signal from each peripheral function
pin is selected by this circuit and the signal is used as the INT00 (channel 0) input of external interrupt.
This enables the input signals to the peripheral function pins to also serve as external interrupt pins.
