S5920 – PCI Product: PCI Configuration Registers
Each PCI bus device contains a unique 256-byte region called its configuration header space. Portions of this con-
figuration header are mandatory in order for a PCI agent to be in full compliance with the PCI specification. This
section describes each of the configuration space fields—its address, default values, initialization options, and bit
definitions—and also provides an explanation of its intended usage.
