 *   @n@b CSL_CPINTC_open
 *
 *   @b Description
 *   @n This API opens the interrupt controller instance. This should always
 *      be the first call to the CSL CPINTC Functional layer. The handle 
 *      which is returned from this call should be passed in all subsequent
 *      CSL API's.
 *      
 *   <b> Return Value </b> 
 *   @n  CSL_CPINTC_HANDLE  - Handle to the CPINTC Module
 *   @n  0                  - Error. 
 *
 *   <b> Pre Condition </b>
 *   @n  None
 *
 *   <b> Post Condition </b>
 *   @n  None 
 *    
 *   @b  Affects
 *   @n  None.
 *
 *   @b  Example
 *   @verbatim
        CSL_CPINTC_HANDLE   hnd;
        ...
        hnd = CSL_CPINTC_open (0);    // Opens CPINTC Instance 0
        ...
