Clearing the Interrupt Status and Interrupt Signal
Interrupt status bits are used to identify the input signal bit being used for requesting an interrupt.
When an interrupt status is input, the interrupt request signal and the interrupt status are cleared
automatically.
CAUTION
-
All of the interrupt status bits are set to 0 when the power is turned on.
-
If an interrupt mask bit has been set to disable interrupts, the interrupt status bit is not set even when
the input signal changes its level.
