An NMI interrupt is generated when the input to the P8
is a non-maskable external interrupt. The pin level can be checked in the port P8

This pin cannot be used as a normal port input.
Notes:
If the direction register of any of P10
input interrupt is generated. A key input interrupt can also be used as a key-on wakeup function for cancel-
ling the wait mode or stop mode. However, if you intend to use the key input interrupt, do not use P10

interrupt.

occurring regardless of the setting in the interrupt control register. When “1” is set in the key input interrupt
disable register, there is no input via the port pin even when the direction register is set to input.
