APIC Bus Functional Description
APIC Interrupt Mapping, APIC0 Agent
IRQ #
NOTES:
1. IRQ 14 and 15 may only be driven directly from the pins when in Legacy IDE mode.
2. NO from external devices, YES of access from processor
3. In APIC mode, the PCI interrupts A:H are mapped to IRQ[16:23].
4. When an interrupt is used for PCI IRQ[A:H], SCI, or TCO, it should not be used for ISA-style
5. When programming the polarity of internal interrupt sources on the APIC, interrupts 0
6. When IRQ11 is used for MMT #2, software should ensure IRQ 11 is not shared with any other
7. PCI Message interrupts are not prevented by hardware in these cases. However, the system

must not program these interrupts as edge-triggered (as required for PCI message
interrupts) because the internal and external PIRQs on these inputs must be programmed in
level-triggered modes.
