Processor Configuration Registers  
2.6.22  
INTRLINE—Interrupt Line Register  
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.

Description  
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.  
A value of 1 corresponds to INTA# (Default)  
A value of 2 corresponds to INTB#  
A value of 3 corresponds to INTC#  
A value of 4 corresponds to INTD#  
2:0  
RW-O  
1h  
Uncore  
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.
