  • Page 108: Pci Interrupt Routing Map

    MS440GX Motherboard Product Guide PCI Interrupt Routing Map This section describes interrupt sharing and how the interrupt signals are connected between the PCI expansion slots and onboard PCI devices. The PCI specification states how interrupts can be shared between devices attached to the PCI bus. In most cases, the small amount of latency added by interrupt sharing does not affect the operation or throughput of the devices.

  • Page 109: Interrupt Routing Example

    Technical Reference Interrupt Routing Example IF an add-in card in the second PCI slot has one interrupt (group INTA) THEN in this slot, an interrupt source from group INTA connects to the PIRQB signal WHICH is not connected to any onboard interrupt sources AND IF there are no other add-in cards THEN this card does not share its interrupt with any other devices.
