****************************************************************************** - * @file system_stm32f2xx.c - * @author MCD Application Team - * @version V1.0.0 - * @date 18-April-2011 - * @brief CMSIS Cortex-M3 Device Peripheral Access Layer System Source File. - * This file contains the system clock configuration for STM32F2xx devices, - * and is generated by the clock configuration tool - * "STM32f2xx_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_stm32f2xx.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 (16 MHz) is used as system clock source. - * Then SystemInit() function is called, in "startup_stm32f2xx.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 25MHz, refer to "HSE_VALUE" define - * in "stm32f2xx.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: - *============================================================================= - *============================================================================= - * Supported STM32F2xx device revision | Rev B and Y - *----------------------------------------------------------------------------- - * System Clock source | PLL (HSE) - *----------------------------------------------------------------------------- - * SYSCLK(Hz) | 100000000 - *----------------------------------------------------------------------------- - * HCLK(Hz) | 100000000 - *----------------------------------------------------------------------------- - * AHB Prescaler | 1 - *----------------------------------------------------------------------------- - * APB1 Prescaler | 4 - *----------------------------------------------------------------------------- - * APB2 Prescaler | 2 - *----------------------------------------------------------------------------- - * HSE Frequency(Hz) | 25000000 - *----------------------------------------------------------------------------- - * PLL_M | 25 - *----------------------------------------------------------------------------- - * PLL_N | 200 - *----------------------------------------------------------------------------- - * PLL_P | 2 - *----------------------------------------------------------------------------- - * PLL_Q | 5 - *----------------------------------------------------------------------------- - * PLLI2S_N | NA - *----------------------------------------------------------------------------- - * PLLI2S_R | NA - *----------------------------------------------------------------------------- - * I2S input clock | NA - *----------------------------------------------------------------------------- - * VDD(V) | 3.3 - *----------------------------------------------------------------------------- - * Flash Latency(WS) | 3 - *----------------------------------------------------------------------------- - * Prefetch Buffer | ON - *----------------------------------------------------------------------------- - * Instruction cache | ON - *----------------------------------------------------------------------------- - * Data cache | ON - *----------------------------------------------------------------------------- - * Require 48MHz for USB OTG FS, | Enabled - * SDIO and RNG clock | - *----------------------------------------------------------------------------- - *============================================================================= - ****************************************************************************** - * @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.
