+  ******************************************************************************
+  * @file    system_stm32f1xx.c
+  * @author  MCD Application Team
+  * @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.
+  *
