 *   @b Description
 *   @n This function initializes the device registers with the register-values
 *      provided through the config data structure.
 *
 *   @b Arguments
 *   @verbatim
            hWdt            Handle to the watchdog timer instance

            config          Pointer to the config structure containing the
                            device register values
     @endverbatim
