10.3.7
NMIFCR is a 32-bit readable and conditionally writable register that has an NMI flag (NMIFL bit)
which can be read or cleared by software. The NMIFL bit is automatically set to 1 by hardware
when an NMI interrupt is detected by the INTC. Writing 0 to the NMIFL bit clears it.
The value of the NMIFL bit does not affect acceptance of the NMI by the CPU. Although an NMI
request detected by the INTC is cleared when the CPU accepts the NMI, the NMIFL bit is not
cleared automatically. Even if 0 is written to the NMIFL bit before the NMI request is accepted by
the CPU, the NMI request is not canceled.

Description
NMI Input Level
Indicates the level of the signal input to the NMI pin;
that is, this bit is read to determine the level on the NMI
pin. This bit cannot be modified.
0: The low level is being input to the NMI pin
1: The high level is being input to the NMI pin
Reserved
These bits are always read as 0. The write value
should always be 0.
