I/OxAPIC Interrupt Controller Registers (Function 1)
The Intel® 6702PXH 64-bit PCI Hub contains one I/OxAPIC controller, which reside on the
primary bus. The intended use of this controller for the Intel® 6702PXH 64-bit PCI Hub is to have
the interrupts from PCI bus A connected to the interrupt controller on Function 1.
