 * @section Introduction
 *
 * @subsection xxx Purpose and Scope
 * The purpose of this document is to identify a set of common CSL APIs
 * for the McASP Module across variousdevices. 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 McASP Module. While in 
 * other cases this list of APIs may not be sufficient to cover all the features 
 * of a particular McASP Module. The CSL developer should use his discretion in 
 * designing new APIs or extending the existing ones to cover these.
 *
 * @subsection aaa Terms and Abbreviations
 *  -#  CSL:  Chip Support Library
 *  -#  API:  Application Programmer Interface
 *  -# MCASP: Application Programmer Interface
