Port [A/B/C/D/E] Input Signal De-bounce Enable
DBEN[n]used to enable the de-bounce function for each corresponding bit. If the input
signal pulse width can’t 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 is controlled by DBNCECON[3:0]
The DBEN[n] is used for “edge-trigger” interrupt only, and ignored for “level trigger”
interrupt
1 = The bit[n] de-bounce function is enabled
0 = The bit[n] de-bounce function is disabled
The de-bounce function is valid for edge triggered interrupt. If the interrupt mode is
level triggered, the de-bounce enable bit is ignored.
