IMD0	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 interrup. 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.
