- ******************************************************************************
- * @file system_stm32f10x.c
- * @author MCD Application Team
- * @version V3.5.0
- * @date 11-March-2011
- * @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_stm32f10x_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_stm32f10x_xx.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 8 MHz (or 25 MHz, depedning on
- * the product used), refer to "HSE_VALUE" define in "stm32f10x.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.

- 2. Please make sure that the selected System clock doesn't exceed your device's

- - For Low, Medium and High density devices an external 8MHz crystal is
- used to drive the System clock.
- - For Connectivity line devices an external 25MHz crystal is used to drive
- the System clock.
- If you are using different crystal you have to adapt those functions accordingly.
