Prefetchable Memory Base Upper Portion (PMBU) — R/W. Upper 32-bits of the
prefetchable address base.
Prefetchable Memory Limit Upper Portion (PMLU) — R/W. Upper 32-bits of the
prefetchable address limit.
Capabilities Pointer (PTR) — RO. Indicates that the pointer for the first entry in the
capabilities list is at 50h in configuration space.
Interrupt Pin (IPIN) — RO. The PCI bridge does not assert an interrupt.
Interrupt Line (ILINE) — R/W. Software written value to indicate which interrupt line
(vector) the interrupt is connected to. No hardware action is taken on this register.
Since the bridge does not generate an interrupt, BIOS should program this value to FFh
as per the PCI bridge specification.
