@author MCD Application Team + * @version V1.3.1 + * @date 17-January-2014 + * @brief CMSIS Cortex-M0 Device Peripheral Access Layer System Source File. + * This file contains the system clock configuration for STM32F0xx devices, + * and is generated by the clock configuration tool + * STM32F0xx_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_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 Range) 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. 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 "stm32f0xx.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: + *============================================================================= + * System Clock Configuration + *============================================================================= + * System Clock source | PLL(HSE) + *----------------------------------------------------------------------------- + * SYSCLK | 48000000 Hz + *----------------------------------------------------------------------------- + * HCLK | 48000000 Hz + *----------------------------------------------------------------------------- + * AHB Prescaler | 1 + *----------------------------------------------------------------------------- + * APB1 Prescaler | 1 + *----------------------------------------------------------------------------- + * APB2 Prescaler | 1 + *----------------------------------------------------------------------------- + * HSE Frequency | 8000000 Hz + *----------------------------------------------------------------------------- + * PLL MUL | 6 + *----------------------------------------------------------------------------- + * VDD | 3.3 V + *----------------------------------------------------------------------------- + * Flash Latency | 1 WS + *----------------------------------------------------------------------------- + *============================================================================= + ****************************************************************************** + * @attention + * + *
