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
0: Interrupt request is detected on the falling edge of the
1: Interrupt request is detected on the rising edge of the
Reserved
These bits are always read as 0. The write value should
always be 0.
