Interrupt Line
This register communicates interrupt line routing
information. Power-On-Self-Test (POST) software writes
the routing information into this register as it configures
the system. This register indicates the system interrupt
controller input to which this PCI function’s interrupt pin
connects. System architecture determines the values in
this register.
Interrupt Pin
This read only register indicates which interrupt pin the
PCI function uses. This register is set to 0x01, which indi-
cates that PCI function presents interrupts on the INTA/
or ALT_INTA/ pins. The Interrupt Request Routing Mode
bits, bits [9:8] in the
mine if the function presents interrupts on INTA/,
ALT_INTA/, or both.
