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