Target Port Number (PN) — RO. This field indicates the target port number is 15h
(Intel
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 FD.ZD (offset 3418h, bit 4) is set, the link to Intel High
Definition Audio is not valid (return 0). When FD.ZD is cleared, the link to Intel High
Definition Audio is valid (return 1).

Reserved
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 #27.
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 5h (root
port #5).
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 FD.PE5D (offset 3418h, bit 20) is set, the link for this
root port is not valid (return 0). When FD.PE5D is cleared, the link for this root port is
