+ *
+ * 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
+ *-----------------------------------------------------------------------------
