Table 166: Port VC Status Register (Offset 0x14A)
Bit Field Description Init Access
0 VC Arbitration Table Status Not supported 0 RO
Table 167: VC Resource Capability Register (Offset 0x14C)
Bit Field Description Init Access
31:24 Port Arbitration Table Offset Must be set to 0 for endpoint devices 0x00 RO
22:16 Maximum Time Slots Must be set to 0 for endpoint devices 0x00 RO
15 Reject Snoop Transactions Must be set to 0 for endpoint devices 0 RO
14 Advanced Packet Switching VC may be used for non-AS packet traffic 0 RO

Table 168: VC Resource Control Register (Offset 0x150)
Bit Field Description Init Access
31 VC Enable Default VC is always enabled 1 RO
26:24 VC ID Default VC = 0 0x0 RO
19:17 Port Arbitration Select Must be set to 0 for endpoint devices 0x0 RO
16 Load Port Arbitration Table Must be set to 0 for endpoint devices 0 RO
7:0 TC/VC Map A 1 at bit n indicates that TC n is mapped to VC0 (bit
0 is read only and is hardwired to 1)
