Port [A/B/C/D/E] Edge or Level Detection Interrupt Control
IMD[n] is used to control the interrupt is by level trigger or by edge trigger. If the
interrupt is by edge trigger, the trigger source can be controlled by de-bounce. If the
interrupt is by level trigger, the input source is sampled by one HCLK clock and
generates the interrupt.
1 = Level trigger interrupt
0 = Edge trigger interrupt
If set pin as the level trigger interrupt, then only one level can be set on the registers
GPIOx_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.
