If any of bits KMIMR15 to KMIMR8 or WUEMRB7 to WUEMRB0 is cleared to 0, interrupt
input from the ,54: pin will be ignored. When pins .,1: to .,13, .,148#to .,1;, or :8(: to
:8(3 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).

5.4.1
There are four types of external interrupts: NMI, IRQ7 to IRQ0, KIN15 to KIN0 and WUE7 to
WUE0. WUE7 to WUE0 and KIN15 to KIN8 share the IRQ7 interrupt source, and KIN7 to KIN0
share the IRQ6 interrupt source. Of these, NMI, IRQ7, IRQ6 , and IRQ2 to IRQ0 can be used to
restore this LSI from software standby mode.
