Interrupt Falling-Edge Event Enable Register (IFEER)
This register is used to enable falling-edge triggered events on the corresponding interrupt pads.
NOTE
If both the IREER[IREE] and IFEER[IFEE] bits are cleared for the same
interrupt source, the interrupt status flag for the corresponding external
interrupt will never be set. If IREER[IREE] and IFEER[IFEE] bits are set
for the same source the interrupts are triggered by both rising edge events
and falling edge events.
