Interrupt Pin (IPIN) — RO. This field indicates the interrupt pin driven by the root
port. At reset, this register takes on the following values, which reflect the reset state
of the D28IP register in chipset configuration space:
NOTE: The value that is programmed into D28IP is always reflected in this register.
Interrupt Line (ILINE) — R/W. Default = 00h. Software written value to indicate
which interrupt line (vector) the interrupt is connected to. No hardware action is taken
on this register.
