Description
NMI Input Level
Indicates the state of the signal input to the NMI pin.
This bit can be read to determine the NMI pin level.
This bit cannot be modified.
0: State of the NMI input is low
1: State of the NMI input is high
Reserved
These bits are always read as 0. The write value
should always be 0.
NMI Edge Select
