4.3.1.1Bus Number

PCI configuration space protocol requires that all PCI buses in a system be assigned a bus number. Furthermore, bus numbers must be assigned in ascending order within hierarchical buses. Each PCI bridge has registers containing its PCI bus number and subordinate PCI bus number, which must be loaded by POST code. The Subordinate PCI bus number is the bus number of the last hierarchical PCI bus under the current bridge. The PCI bus number and the Subordinate PCI bus number are the same in the last hierarchical bridge.

4.3.1.2Device Number and IDSEL Mapping

Each device under a PCI bridge has its IDSEL input connected to one bit out of the PCI bus address/data signals AD[31::11] for the PCI bus. Each IDSEL-mapped AD bit acts as a chip select for each device on PCI. The host bridge responds to a unique PCI device ID value, that along with the bus number, cause the assertion of IDSEL for a particular device during configuration cycles. The following table shows the correspondence between IDSEL values and PCI device numbers for the PCI bus. The lower 5-bits of the device number are used in CONFIG_ADDRESS bits [15::11].
