Description
Target Port Number (PN) — RO. This field indicates the target port number is 6h (root
port #6).
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.PC2 (offset 0224h, bits 1:0) is ‘01’ or FD.PE6D
(offset 3418h, bit 21) is set, the link for this root port is not valid (return 0). When
RPC.PC is ‘00’ and FD.PE6D is cleared, the link for this root port is valid (return 1).
