Multi-Function Device — RO.
0 = Single-function device.
1 = Multi-function device.
Configuration Layout— RO. This field is determined by bit 2 of the MPC register
(D28:F0-5, Offset D8h, bit 2).
00h = Host Bridge.
01h = PCI-to-PCI bridge.
Subordinate Bus Number (SBBN) — R/W. Indicates the highest PCI bus number below
the bridge.
Secondary Bus Number (SCBN) — R/W. Indicates the bus number the port.
Primary Bus Number (PBN) — R/W. Indicates the bus number of the backbone.
