Virtual Channel Enable (EN) — RO. Always set to 1. Virtual Channel 0 cannot be
disabled.
Reserved.
Virtual Channel Identifier (VCID) — RO. Indicates the ID to use for this virtual channel.
Reserved.
Port Arbitration Select (PAS) — R/W. 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
