Load Port Arbitration Table (LAT) — RO. The root complex does not implement an
arbitration table for this virtual channel.
Reserved
Transaction Class / Virtual Channel Map (TVM) — R/W. Indicates which
transaction classes are mapped to this virtual channel. When a bit is set, this
transaction class is mapped to the virtual channel.
Reserved
Reserved
VC Negotiation Pending (NP) — RO. When set, indicates the virtual channel is still
