Bus Number (BN) — RO. This field indicates the root port is on bus #0.
Device Number (DN) — RO. This field indicates the root port is on device #28.
Function Number (FN) — RO. This field indicates the root port is on function #0.
Reserved
Target Port Number (PN) — RO. This field indicates the target port number is 2h (root port #2).
Target Component ID (TCID) — R/WO. This field returns the value of the ESD.CID (offset
0104h, bits 23:16) field programmed by platform BIOS, since the root port is in the same
component as the RCRB.
Reserved
Link Type (LT) — RO. This bit indicates that the link points to a root port.
Link Valid (LV) — RO. When RPC.PC (offset 0224h, bits 1:0) is ‘01’, ‘10’, or ‘11’, or FD.PE2D
(offset 3418h, bit 17) is set, the link for this root port is not valid (return 0). When RPC.PC is ‘00’
and FD.PE2D is cleared, the link for this root port is valid (return 1).
