* @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.
