Bit
Name
Description
7
IRQ15_SEL
IRQ15 Edge or Level Select. Selects PIC IRQ15 sensitivity configuration.
0: Edge; 1: Level. (Note 1)
Note 1. If ICW1 bit 3 in the PIC is set as level, it overrides the settings of this bit. This bit is provided to configure a PCI
interrupt mapped to IRQ[x] on the PIC as level-sensitive (shared).
6
IRQ14_SEL
IRQ14 Edge or Level Select. Selects PIC IRQ14 sensitivity configuration.
0: Edge; 1: Level. (Note 1)
5
RSVD
Reserved. Write to 0.
4
IRQ12_SEL
IRQ12 Edge or Level Select. Selects PIC IRQ12 sensitivity configuration.
0: Edge; 1: Level. (Note 1)
3
IRQ11_SEL
IRQ11 Edge or Level Select. Selects PIC IRQ11 sensitivity configuration.
0: Edge; 1: Level. (Note 1)
2
IRQ10_SEL
IRQ10 Edge or Level Select. Selects PIC IRQ10 sensitivity configuration.
0: Edge; 1: Level. (Note 1)
1
IRQ9_SEL
IRQ9 Edge or Level Select. Selects PIC IRQ9 sensitivity configuration.
0: Edge; 1: Level. (Note 1)
0
RSVD
Reserved. Write to 0.
