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