WUEMRB is an 8-bit readable/writable register that performs mask control for the wakeup event
interrupt inputs (pins WUE7 to WUE0). A wakeup event interrupt is enabled by clearing the
corresponding mask bit to 0.
WUEMRB is initialized to H'FF by a reset and in hardware standby mode.
Bits 7 to 0—Wakeup Event Interrupt Mask (WUEMR7 to WUEMR0): These bits control
wakeup event interrupt requests (WUE7 to WUE0).

Figure 5.2 shows the relationship between interrupts IRQ7 and IRQ6, interrupts KIN15 to KIN0,
interrupts WUE7 to WUE0, and registers KMIMR, KMIMRA, and WUEMRB.
