Port Arbitration Select (PAS) — R/W. This field indicates which port table is being programmed. The
root complex takes no action on this setting since the arbitration is fixed and there is no arbitration
table.
Load Port Arbitration Table (LAT) — RO. The root port does not implement an arbitration table for
this virtual channel.
Reserved.
Transaction Class / Virtual Channel Map (TVM) — R/W. This field 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. Transaction class 0 must always mapped to VC0.
Reserved.
VC Negotiation Pending (NP) — RO.
0 = Negotiation is not pending.
1 = Indicates the Virtual Channel is still being negotiated with ingress ports.
Port Arbitration Tables Status (ATS). There is no port arbitration table for this VC, so this bit is
