Description
NMI Input Level
Sets the level 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: 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
0: Interrupt request is detected on falling edge of NMI
1: Interrupt request is detected on rising edge of NMI
IRQ0 Sense Select
This bit sets the IRQ0 interrupt request detection
mode.
0: Interrupt request is detected on low level of IRQ0
1: Interrupt request is detected on edge of IRQ0 input
IRQ1 Sense Select
This bit sets the IRQ1 interrupt request detection
mode.
0: Interrupt request is detected on low level of IRQ1
1: Interrupt request is detected on edge of IRQ1 input
