1 how to use Master Operation, especially how to use Avalon Configuration to set the computer's address,which is mapped to PCI_Bus_Access? 

2 how to write data to the Control_Register_Access?why the data is always 0 when I read data from the Control_Register_Access? why I can't write data to the Control_Register_Access. 

Thank you very much,If you can give me any suggestions and keys.
