_______
An NMI interrupt request is generated when input on the NMI pin changes state from high to low, after the
NMI interrupt was enabled by writing a “1” to bit 4 of register PM2. The NMI interrupt is a non-maskable
interrupt, once it is enabled.
The input level of this NMI interrupt input pin can be read by accessing the P8 register’s P8_5 bit.
NMI is disabled by default after reset (the pin is a GPIO pin, P8
register. Once enabled, it can only be disabled by a reset signal.
The NMI input has an effective digital debounce function for a noise rejection. Refer to "17.6 Digital
Debounce function" for this detail. When using NMI interrupt to exit stop mode, set the NDDR register to
"FF
A key input interrupt is generated when input on any of the P10
PD10_7 bits in the PD10 register set to “0” (input) goes low. Key input interrupts can be used as a key-on
wakeup function, the function to exit wait or stop mode. However, if you intend to use the key input interrupt,
do not use P10
interrupt. Note, however, that while input on any pin which has had the PD10_4 to PD10_7 bits set to “0”
(input mode) is pulled low, inputs on all other pins of the port are not detected as interrupts.
