 *   @n@b CSL_tmrHwSetupRaw
 *
 *   @b Description
 *   @n This function initializes the device registers with the register-values
 *      provided through the Config Data structure.
 *
 *   @b Arguments
 *   @verbatim
            hTmr            Handle to the TMR instance

            config          Pointer to config structure
     @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li            CSL_SOK               - Configuration successful
 *   @li            CSL_ESYS_BADHANDLE    - Invalid handle
 *   @li            CSL_ESYS_INVPARAMS    - Configuration is not
                                            properly initialized
 *   <b> Pre Condition </b>
 *   @n  None
 *
 *   <b> Post Condition </b>
 *   @n  The registers of the specified TMR instance will be setup
 *       according to input configuration structure values.
 *
 *   @b Modifies
 *   @n Hardware registers of the specified TMR instance.
 *
 *   @b Example
