Figure 5.2 shows the relationship between interrupts IRQ7 and IRQ6, interrupts KIN15 to KIN0,
interrupts WUE7 to WUE0, and registers KMIMRA, KMIMR, and WUEMRB.
If any of bits KMIMR15 to KMIMR8 or WUEMRB7 to WUEMRB0 is cleared to 0, interrupt
input from the IRQ7 pin will be ignored. When pins KIN7 to KIN0, KIN15 to KIN8, or WUE7 to
WUE0 are used as key-sense interrupt input pins or wakeup event interrupt input pins, either low-
level sensing or falling-edge sensing must be designated as the interrupt sense condition for the
corresponding interrupt source (IRQ6 or IRQ7).
