At that time, the master_data pointer is set up - and the slave can access any io registers of the master device (in the case - the slave is bound to it). Otherwise it doesn't need this functions and - therfor they may not be initialized. - - The other functions are just for convenience, as they are for sure used by - most/all of the codecs.
