/* NMIIrqIsOn flag is defined in libpp.a, and appears to be set when an NMI

call back into parts of the OS?)
The esp_iot_rtos_sdk disables all interrupt manipulations while this
flag is set.
It's also referenced from some other blob libraries (not known if
read or written there).
ESPTODO: It may be possible to just read the 'ps' register instead
of accessing thisvariable.
