Section 21 Pin Function Controller (PFC)
21.1.12 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 D control register H4 (PDCRH4) and port E
control register L4 (PECRL4). When PDCRH4 or PECRL4 selects another function, the IFCR
setting does not affect the pin function.
