V1STS—Virtual Channel 1 Resource Status Register
Offset Address: 0026–0027h
Default Value:
PAT—Port Arbitration Table
Offset Address: 0030–006Fh
Default Value:
This is a 64-byte register that contains the arbitration table to be loaded into the port
arbitration table. Every 4-bits contains an entry for one of the downstream PCI-Express
ports or a 0h to indicate idle. The ports are mapped as follows:
This table is copied to an internal structure used during port arbitration when
V1CTL.PAS is set to 04h, and V1CTL.LAT is set to 1.

VC Negotiation Pending (NP) — RO. When set, indicates the virtual channel is still
being negotiated with ingress ports.
Port Arbitration Tables Status (ATS) — RO. Indicates the coherency status of the
port arbitration table. This bit is set when LAT (offset 000Ch:bit 0) is written with
value 1 and PAS (offset 0014h:bits19:17) has value of 4h. This bit is cleared after the
table has been updated.
