Target Port Number (PN) — RO. 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. 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).
Reserved
Reserved
Bus Number (BN) — RO. Indicates the root port is on bus #0.
Device Number (DN) — RO. Indicates the root port is on device #28.
Function Number (FN) — RO. Indicates the root port is on function #1.
Reserved
Target Port Number (PN) — RO. Indicates the target port number is 3h (root port
#3).
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. Indicates that the link points to a root port.
Link Valid (LV) — RO. When RPC.PC (offset 0224h, bits 1:0) is ‘11’, or FD.PE3D
(offset 3418h, bit 18) is set, the link for this root port is not valid (return 0). When
RPC.PC is ‘00’, ‘01’, or “10’, and FD.PE3D is cleared, the link for this root port is valid
(return 1).
