Interrupt request pin
Interrupt receiving priority: IRQ15 is highest priority
and IRQ1 is lowest.
A choice of four interrupt waveforms is available by
mode setting for each of the 15 pins independently,
including “H” level, “L” level, rising edge, and falling
edge.
Each input has a filtering function for short pulse
signals, by which an interrupt request is recognized
once a signal is detected at active level at three
successive rising edges of the internal clock signal.
Once an interrupt request is detected, it passes
through priority control and masking control and is
output at the IRL<3:0> pins as an interrupt request to
the MPU.
If these pins are not used, they should be fixed at
inactive level.
