Figure 1.14.11. Block diagram of key input interrupt
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
03F0
This pin cannot be used as a normal port input.
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
P10
“L” level is input to any pin that has not been disabled for input, inputs to the other pins are not detected as
an interrupt.
