The NMI interrupt occurs when a signal applied to the NMI pin changes from a high-level ("H") signal to a
low-level ("L") signal. The NMI interrupt is a non-maskable interrupt. Although the P8
the NMI interrupt input pin, the P8_5 bit in the P8 register indicates the input level for this pin.
NOTES:
Key input interrupt request is generated when one of the signals applied to the P10
mode is on the falling edge. The key input interrupt can be also used as key-on wake-up function to exit wait
or stop mode. To use the key input interrupt, do not use P10
shows a block diagram of the key input interrupt. When an "L" signal is applied to any pins in input mode,
signals applied to other pins are not detected as an interrupt request signal.
When the PSC_7 bit in the PSC register
occurs regardless of interrupt control register settings. When the PSC_7 bit is set to "1", no input from a
port pin is available even when in input mode.
