(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
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.
