Attention Button Interrupt Mask (ABIM): If this bit is set, system interrupts
from Attention Button Press Detected are masked. The state of this bit has no
effect on the state of the Attention Button Press Detected bit.
Isolated Power Fault Interrupt Mask (IPFIM): If this bit is set, system
interrupts from Isolated Power Fault Detected are masked. The state of this
bit has no effect on the state of the Isolated Power Fault Detected bit.
Card Presence Interrupt Mask (CPIM): If this bit is set, system interrupts
from Card Presence Change Detected are masked. The state of this bit has
no effect on the state of the Card Presence Change Detected bit.

I/OxAPIC Interrupt Controller Registers
(Function 1 and 3)
The Intel® 6700PXH 64-bit PCI Hub contains two I/OxAPIC controllers, both of which reside on
the primary bus. The intended use of these controllers for the Intel® 6700PXH 64-bit PCI Hub is to
have the interrupts from PCI bus A connected to the interrupt controller on Function 1, and have
the interrupts on PCI bus B connected to the interrupt controller on Function 3. The Intel®
6702PXH 64-bit PCI Hub supports a single I/OxAPIC controller, corresponding to Function 1.
