+  * @param[in]  u32CmpValue     Setting the window compared value. Valid values are between 0x0 to 0x3F.
+  * @param[in]  u32EnableInt    Enable WWDT time-out interrupt function. Valid values are TRUE and FALSE.

+  * @return     None
+  *
+  * @details    This function makes WWDT module start counting with different counter period by pre-scale setting and compared window value.
+  * @note       This WWDT_CTL register can be write only one time after chip is powered on or reset.
