Section 29 Pin Function Controller (PFC)
29.2.11 IRQOUT Function Control Register (IFCR)
IFCR is a 16-bit readable/writable register that is used to control the IRQOUT/REFOUT pin
output when it is selected as the multiplexed pin function by port B control register L4 (PBCRL4).
When PBCRL4 selects another function, the IFCR setting does not affect the pin function.
