Hi,
I am so sorry for the delay.

it is hte upper address of the BD_ADDR in the standard, anyhow you do not need it it should be an input to the CRC block because it will change according to the system state which will be controlled by the sytem controller.

I think we have to define a way to manage all of the files, blocks and coding style so as to enable others to join hte coding.
I put in hte CVS a vhdl package that defines hte system constants.
We should also agree on hte naming conventions of hte files and ports.

I suggest to follow the open cores vhdl coding style and to put the entity and architecture in different files.
Port names should start with Capital letter and names as in the bluetooth design document.

I'll depend on every one to test and verify his block and if possible to provide the logic resources and timing information after synthesis.

Please let me know your suggestions.
