  * @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
