+ ******************************************************************************
+ * @file system_stm32f30x.c
+ * @author MCD Application Team
+ * @version V1.1.1
+ * @date 28-March-2014
+ * @brief CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
+ * This file contains the system clock configuration for STM32F30x devices,
+ * and is generated by the clock configuration tool
+ * stm32f30x_Clock_Configuration_V1.0.0.xls
+ *
+ * 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
+ * and Divider factors, AHB/APBx prescalers and Flash settings),
+ * depending on the configuration made in the clock xls tool.
+ * This function is called at startup just after reset and
+ * before branch to main program. This call is made inside
+ * the "startup_stm32f30x.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_stm32f30x.s" file, to
+ * configure the system clock before to branch to main program.
+ *
+ * 3. If the system clock source selected by user fails to startup, the SystemInit()
+ * function will do nothing and HSI still used as system clock source. User can
+ * add some code to deal with this issue inside the SetSysClock() function.
+ *
+ * 4. The default value of HSE crystal is set to 8MHz, refer to "HSE_VALUE" define
+ * in "stm32f30x.h" file. 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.
+ *
+ * 5. This file configures the system clock as follows:
