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. - * - ****************************************************************************** - * @attention - * - * THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS - * WITH CODING INFORMATION REGARDING THEIR PRODUCTS IN ORDER FOR THEM TO SAVE - * TIME.
