Data (DATA) — R/W. This 16-bit field is programmed by system software if MSI is
enabled. Its content is driven onto the lower word (PCI AD[15:0]) during the data
phase of the MSI memory write transaction.
Next Capability (NEXT) — RO. This field indicates the location of the next pointer in
the list.
Capability Identifier (CID) — RO. Value of 0Dh indicates this is a PCI bridge
subsystem vendor capability.
Subsystem Identifier (SID) — R/WO. This field indicates the subsystem as identified
by the vendor. This field is write once and is locked down until a bridge reset occurs
(not the PCI bus reset).
Subsystem Vendor Identifier (SVID) — R/WO. This field indicates the manufacturer
of the subsystem. This field is write once and is locked down until a bridge reset occurs
(not the PCI bus reset).
Next Capability (NEXT) — RO. This field indicates that this is the last item in the list.
Capability Identifier (CID) — RO. Value of 01h indicates this is a PCI power
management capability.
