- * |[15:0] |DBEN[n] |Port 0-4 Pin [n] Input Signal De-bounce Enable Control
- * | | |DBEN[n] bit is used to enable the de-bounce function for each corresponding bit.
- * | | |If the input signal pulse width cannot be sampled by continuous two de-bounce sample cycle, the input signal transition is seen as the signal bounce and will not trigger the interrupt.
- * | | |The de-bounce clock source is controlled by DBNCECON[4], one de-bounce sample cycle period is controlled by DBNCECON[3:0].
- * | | |0 = Px.n de-bounce function Disabled.
- * | | |1 = Px.n de-bounce function Enabled.
- * | | |The de-bounce function is valid only for edge triggered interrupt. If the interrupt mode is level triggered, the de-bounce enable bit is ignored.
- * | | |Note1: x = 0~4, n = 0~7.
- * | | |Note2: If Px.n pin is chosen as Power-down wake-up source, user should be disable the de-bounce function before entering Power-down mode to avoid the second interrupt event occurred after system waken up which caused by Px.n de-bounce function.

- * | | |IMD[n] bit is used to control the triggered 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.
- * | | |0 = Edge trigger interrupt.
- * | | |1 = Level trigger interrupt.
- * | | |If the pin is set as the level trigger interrupt, only one level can be set on the registers Px_IEN. If both levels to trigger interrupt are set, the setting is ignored and no interrupt will occur.
- * | | |The de-bounce function is valid only for edge triggered interrupt. If the interrupt mode is level triggered, the de-bounce enable bit is ignored.

- * | | |When setting the IR_EN[n] bit to 1 :
- * | | |If the interrupt is level trigger (IMD[n] is 1), the input Px.n pin will generate the interrupt while this pin state is at high level.
- * | | |If the interrupt is edge trigger (IMD[n] is 0), the input Px.n pin will generate the interrupt while this pin state changed from low to high.
- * | | |0 = Px.n level high or low to high interrupt Disabled.
