19.2.3 NP flag
interrupt requests to prohibit multiple interrupts from being acknowledged.
(2) From INTWDT2 signal
The NP flag is a status flag that indicates that non-maskable interrupt servicing is under execution.
This flag is set when a non-maskable interrupt request signal has been acknowledged, and masks non-maskable
Note FEPSW ← Value that sets NP bit = 1, EP bit = 0
Restoring from non-maskable interrupt servicing executed by the non-maskable interrupt request (INTWDT2)
by using the RETI instruction is disabled. Execute the following software reset processing.
