Port 0-4 Interrupt Mode Control
IMD[n] used to control the interrupt is by level trigger or by edge trigger. If the interrupt is
by edge trigger, the trigger source is control de-bounce. If the interrupt is by level trigger,
the input source is sampled by one clock and the generate the interrupt
0 = Edge trigger interrupt
1 = Level trigger interrupt
If set pin as the level trigger interrupt, then only one level can be set on the registers
Px_IEN. If set both the level to trigger interrupt, the setting is ignored and no interrupt will
occur
The de-bounce function is valid for edge triggered interrupt. If the interrupt mode is level
triggered, the de-bounce enable bit is ignored.
