 *   @n@b CSL_dmaxGetHwSetupFifoXFRParamEntry
 *
 *   @b Description
 *   @n This function initializes the device registers with the appropriate
 *      values provided through the HwSetup Data structure. After the 
 *      Setup is completed, the device is ready for  operation.      
 *      For information passed through the HwSetup Data structure refer
 *   @a CSL_dmaxHwSetup.
 *
 *   @b Arguments
 *   @verbatim
 *    
 *          paramEntry  Pointer to Prameter Table Entry where data 
 *						is to be stored
 *
 *          setup  		Pointer to a dmax FIFO Transfer Setup Object
 *           
 *   @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li                    CSL_SOK - Successful completion of hardware     
 *                                    setup
 *   @li                    CSL_ESYS_ INVPARAMS - Hardware structure is  
 *                                    not properly initialized
 *   @li                    CSL_ESYS_ BADHANDLE - Invalid CSL handle
 *
 *
 *   <b> Pre Condition </b>
 *   @n  Both CSL_dmaxInit() and a CSL_dmaxOpen() must be called
 *
 *   <b> Post Condition </b>
 *   @n  DMAX registers are configured 
 *
 *   @b  Modifies
 *   @n  DMAX registers
 *
 *   @b Example
 *   @verbatim
