PCI Configuration

PCI Interrupt Request Routing

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines

over which devices can send interrupt signals to the microprocessor. The PCI IRQ

pins are typically connected to the PCI bus pins as follows:

DEVICE

MCP1 INT Pin

IDSEL

CLOCK

REQ# / GNT#

PCI Slot

PIRQA

AD17

PCICLK 0

REQ#0 / GNT#0

Mini PCI Slot

PIRQB

AD18

PCICLK 1

REQ#1 / GNT#1

LAN1

PIRQC

AD21

CLKLAN 1

REQ#2 / GNT#2
