Description
NMI Input Level
Sets the level of the signal input at the NMI pin. This bit
can be read from to determine the NMI pin level. This bit
cannot be modified.
0: NMI input level is low
1: NMI input level is high
Reserved
These bits are always read as 0. The write value should
always be 0.
NMI Edge Select
Selects whether the falling or rising edge of the interrupt
request signal at the NMI pin is detected.
0: Interrupt request is detected on falling edge of NMI
1: Interrupt request is detected on rising edge of NMI
Reserved
These bits are always read as 0. The write value should
always be 0.
