PCI Configuration Space CSR (CONFIG CSR)
Configuration and read back of the CONFIG CSR is accomplished by the Host processor via the PCI
bus. These registers assume their default value on assertion of a chip-level reset or when the device
power state transitions from D3 to D0. See
Registers in offsets 00h - 03Fh are standard PCI header registers, as described in the PCI Local Bus
Specification Revision 3.0. Please refer to the specification for further details.
Register 78h is a PCIB specific extension related to power management.
