4.7. Control Shadow

The control shadow interface is used to bring out the settings of the various configuration register fields of the function. These fields are often required in designing the control path of the application layer logic. The application logic decodes information provided on this interface to create a shadow copy. The interface provides updates for primary control signals only. The application logic must read extra information required through the lite_csr interface by reading the configuration register of interest.

Note: Refer to Interfaces and Signals for details on the interface signals.
