NMI Status Register
Each NMI event and status flag is retained across soft reset. This includes all the flags of NMISR register:
FNMIPLL, FNMINVM, FNMIOCDS, FNMIOWD, FNMIMAP, and indirectly, FNMIECC and FNMISUP. In the case of
NMIs with shared source i.e. watchdog, ECC or supply prewarning NMI, the respective indicator or event flags
not located in NMISR are also retained. Refer to Chapter 1.6.5 for identifying the NMI event.
