Datasheet, Volume 2

This register contains interrupt line routing information. The device itself does not use 
this value, rather it is used by device drivers and operating systems to determine 
priority and vector information.

This register specifies which interrupt pin this device uses.

Interrupt Connection (INTCON)
This field is used to communicate interrupt line routing 

information. 
BIOS Requirement: POST software writes the routing information 

into this register as it initializes and configures the system. The 

value indicates to which input of the system interrupt controller 

this device's interrupt pin is connected.

Interrupt Pin (INTPIN)
As a multifunction device, the PCI Express device may specify any 

INTx (x=A,B,C,D) as its interrupt pin.
The Interrupt Pin register indicates which interrupt pin the device 

(or device function) uses. 
1h = Corresponds to INTA# (Default)
2h = Corresponds to INTB#
3h = Corresponds to INTC# 
4h = Corresponds to INTD# 
Devices (or device functions) that do not use an interrupt pin must 

put a 0 in this register. 
The values 05h through FFh are reserved. 
This register is write once. BIOS must set this register to select the 

INTx to be used by this root port.
