+  *                      the "startup_stm32f4xx.s" file.
+  *
+  *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+  *                                  by the user application to setup the SysTick
+  *                                  timer or configure other parameters.
+  *
+  *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+  *                                 be called whenever the core clock is changed
+  *                                 during program execution.

+  *
+  * @note   - The system frequency computed by this function is not the real

+  *             or HSI_VALUE(*) multiplied/divided by the PLL factors.

+  *         (**) HSE_VALUE is a constant defined in stm32f4xx_hal_conf.h file (its value
+  *              depends on the application requirements), user has to ensure that HSE_VALUE
+  *              is same as the real frequency of the crystal used. Otherwise, this function
+  *              may have wrong result.
