+  * @author  MCD Application Team

+  * @brief   CMSIS Cortex-M0 Device Peripheral Access Layer System Source File.

+  *

+  * 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.

+  *

+  * 2. After each device reset the HSI (8 MHz) is used as system clock source.

+  *    Then SystemInit() function is called, in "startup_stm32f0xx.s" file, to

+  *    configure the system clock before to branch to main program.

+  *

+  * 3. This file configures the system clock as follows:

+  *=============================================================================

+  *                         Supported STM32F0xx device

+  *        HCLK(Hz)                               | 8000000

+  *             in voltage and temperature.

+  *         (**) HSE_VALUE is a constant defined in stm32f0xx_hal.h file (default value

+  *              8 MHz), user has to ensure that HSE_VALUE is same as the real
