 * @section Introduction
 *
 * @subsection xxx Purpose and Scope
 * The purpose of this document is to identify a set of common CSL APIs for
 * the MCBSP module across various devices. The CSL developer is expected to
 * refer to this document while designing APIs for these modules. Some of the
 * listed APIs may not be applicable to a given MCBSP module. While other cases
 * this list of APIs may not be sufficient to cover all the features of a
 * particular MCBSP Module. The CSL developer should use his discretion 
 * designing new APIs or extending the existing ones to cover these.

 *                               - CSL_MCBSP_CMD_REG_RESET changed to
 *                                 CSL_MCBSP_CMD_RESET 
 *
 *  July 04, 2005 ds             - Removed support for DX Mode.Hence removed
 *                                 dxState from CSL_McbspHwSetup
 *                               - Removed support for enhanced sample clock
 *                                 mode. 
 *                               - Register Naming convention used for 
 *                                 Multichannel registers are changed according 
 *                                 the changes in cslr_mcbsp.h
 *
 *  July 26, 2005 ds            - Removed control cmd 
 *                                CSL_MCBSP_CMD_IO_MODE_CONTROL. 
 *                                  
 *  Sept 21, 2005 ds            - Removed the DXR and DRR register from the 
 *                                config data structure
 *
 *  Oct  27, 2005 ds            - Removed CSL_MCBSP_QUERY_PID query from 
 *                                CSL_McbspHwStatusQuery
 *
 *  Feb 02 , 2006 ds            - IntEvent added to CSL_McbspHwSetup and 
 *                                removed interrupt mode commands and queries

 *       peripheral. MMR's go to an alternate location.
 *
 *   @b Arguments
 *   @verbatim
