Target Port Number (PN) — R/WO. This field is programmed by platform BIOS to match the port
number of the (G)MCH RCRB that is attached to this RCRB.
Target Component ID (TCID) — R/WO. This field is programmed by platform BIOS to match the
component ID of the (G)MCH RCRB that is attached to this RCRB.
Reserved
Link Type (LT) — RO. This bit indicates that the link points to the (G)MCH RCRB.
Link Valid (LV) — RO. This bit indicates that the link entry is valid.
Base Address Upper (BAU) — R/WO. This field is programmed by platform BIOS to match the
upper 32-bits of base address of the (G)MCH RCRB that is attached to this RCRB.
Base Address Lower (BAL) — R/WO. This field is programmed by platform BIOS to match the
lower 32-bits of base address of the (G)MCH RCRB that is attached to this RCRB.
Target Port Number (PN) — RO. This field indicates the target port number is 1h (root port #1).
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.PE1D (offset 3418h, bit 16) is set, this link is not valid (returns
0). When FD.PE1D is cleared, this link is valid (returns 1).
