Datasheet
Figure 10. Processor Configuration Cycle Flow Chart
Internal Device Configuration Accesses
The processor decodes the Bus Number (Bits 23:16) and the Device Number fields of
the CONFIG_ADDRESS register. If the Bus Number field of CONFIG_ADDRESS is 0 the
configuration cycle is targeting a PCI Bus 0 device.
If the targeted PCI Bus 0 device exists in the processor and is not disabled, the
configuration cycle is claimed by the appropriate device.
