IRQ Pin Digital Filter Enable Register 0 (IRQFLTE0)
FLTENi Bit (IRQi Digital Filter Enable) (i = 0 to 5)
This bit enables the digital filter used for the IRQi pin.
The digital filter is enabled when the FLTENi bit is 1, and disabled when the FLTENi bit is 0.
The IRQi pin level is sampled at the sampling clock cycle specified with the IRQFLTC0.FCLKSELi[1:0] bits. When the
sampled level matches three times, the output level from the digital filter changes.
For details of the digital filter, see
section 14.4.7, Digital Filter
