-  * 1. This file provides two functions and one global variable to be called from

-  *    user application:

-  *      - SystemInit(): This function is called at startup just after reset and 

-  *                      before branch to main program. This call is made inside

-  *                      the "startup_stm32f0xx.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.

-   * @brief  Update SystemCoreClock variable according to Clock Register Values.

-  *         The SystemCoreClock variable contains the core clock (HCLK), it can

-  *         be used by the user application to setup the SysTick timer or configure

-  *         other parameters.

-  *

-  * @note   Each time the core clock (HCLK) changes, this function must be called

-  *         to update SystemCoreClock variable value. Otherwise, any configuration

-  *         based on this variable will be incorrect.

-  *

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

-  *           frequency in the chip. It is calculated based on the predefined

-  *           constant and the selected clock source:

-  *

-  *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*)

-  *

-  *           - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(**)

-  *

-  *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**)

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

-  *

-  *         (*) HSI_VALUE is a constant defined in stm32f0xx_hal_conf.h file (default value

-  *             8 MHz) but the real value may vary depending on the variations

-  *             in voltage and temperature.

-  *

-  *         (**) HSE_VALUE is a constant defined in stm32f0xx_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.

-  *

-  *         - The result of this function could be not correct when using fractional

-  *           value for HSE crystal.

-  *

-  * @param  None

-  * @retval None
