8.1.20 INTRLINE1—Interrupt Line (D1:F0)
PCI Device:
Address Offset:
Default Value:
Access:
Size:
This register contains interrupt line routing information. The device itself does not use this value;
rather device drivers and operating systems use it to determine priority and vector information.

Default
R/W Interrupt Connection: This field is used to communicate interrupt line routing
00h information. POST software writes the routing information into this register as it
initializes and configures the system. The value in this register indicates which
input of the system interrupt controller this device's interrupt pin is connected to.
Access &
Default
RO Interrupt Pin: As a single function device, the PCI Express* device specifies
01h INTA as its interrupt pin.
