Section 17 Pin Function Controller (PFC)
17.1.9 IRQOUT Function Control Register (IFCR)
IFCR is a 16-bit readable/writable register that is used to control the IRQOUT pin output when it
is selected as the multiplexed pin function by port E control register L4 (PECRL4). When
PECRL4 selects another function, the IFCR setting does not affect the pin function.
