The register fields are defined as follows:

REG

Register Number.

Configuration Cycles: Identifies a target double word within a target’s configuration space. This field is copied to the PCI AD bus during the address phase of a Configuration cycle.

Special Cycles: This field must be written with all 0s.

FUN

Function Number.

Configuration Cycles: Identifies a function number within a target’s configuration space. This field is copied to the PCI AD bus during the address phase of a Configuration cycle.

Special Cycles: This field must be written with all 1s.

DEV

Device Number.

Configuration Cycles: Identifies a target’s physical PCI device number. Refer to the section on Generating PCI Configuration Cycles for a description of how this field is encoded.

Special Cycles: This field must be written with all 1s.
