3.7.6.1.4. Requested NMI Mode

Any interrupt can be nonmaskable, depending on the configuration of the EIC. An NMI typically signals a critical system event requiring immediate handling, to ensure either system stability or real-time performance.

status.IL and RIL are ignored for nonmaskable interrupts.
