-  * @file    system_stm32f0xx.c

-  * @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

-  *-----------------------------------------------------------------------------

-  *        System Clock source                    | HSI

-  *-----------------------------------------------------------------------------

-  *        SYSCLK(Hz)                             | 8000000

-  *-----------------------------------------------------------------------------

-  *        HCLK(Hz)                               | 8000000

-  *-----------------------------------------------------------------------------

-  *        AHB Prescaler                          | 1

-  *-----------------------------------------------------------------------------

-  *        APB1 Prescaler                         | 1

-  *         other parameters.

-  *         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:

-  *

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

-  *

-  *         (*) HSI_VALUE is a constant defined in stm32f0xx_hal.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.h file (default value

-  *              8 MHz), 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
