  * @version V4.2.0
  * @date    31-March-2017
  * @brief   CMSIS Cortex-M3 Device Peripheral Access layer System Source File.
  * 
  * 1.  This file provides two functions and one global variable to be called from 
  *     user application:
  *      - SystemInit（）: Setups the system clock （System clock source PLL Multiplier
  *                      factors AHB/APBx prescalers and Flash settings）. 
  *                      This function is called at startup just after reset and 
  *                      before branch to main program. This call is made inside
  *                      the “startup_stm32f1xx_xx.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_stm32f1xx_xx.s“ file to
  *    configure the system clock before to branch to main program.
  *
  * 4. The default value of HSE crystal is set to 8 MHz （or 25 MHz depending on
  *    the product used） refer to “HSE_VALUE“. 
  *    When HSE is used as system clock source directly or through PLL and you
  *    are using different crystal you have to adapt the HSE value to your own
  *    configuration.
