Multi-Function Device — RO. This bit is 0 to indicate a single function device.
Header Type — RO. 8-bit field identifies the header layout of the configuration space, which is a PCI-
to-PCI bridge in this case.
Primary Bus Number — RO. This field indicates the bus number of the hub interface and is
hardwired to 00h.
Secondary Bus Number — R/W. This field indicates the bus number of PCI. Note: when this
number is equal to the primary bus number (i.e., bus #0), the Intel
configuration cycles to this bus number as Type 1 configuration cycles on PCI.
Subordinate Bus Number — R/W. This field specifies the highest PCI bus number below the hub
interface to PCI bridge. If a Type 1 configuration cycle from the hub interface does not fall in the
Secondary-to-Subordinate Bus ranges of Device 30, the Intel
back to the hub interface.
