* @brief CMSIS STM32F1xx Device Peripheral Access Layer Header File.
*
* The file is the unique include file that the application programmer
* is using in the C source code, usually in main.c. This file contains:
* - Configuration section that allows to select:
* - The STM32F1xx device used in the target application
* - To use or not the peripheral's drivers in application code(i.e.
* code will be based on direct access to peripheral's registers
* rather than drivers API), this option is controlled by
* "#define USE_HAL_DRIVER"

******************************************************************************
* @file system_stm32f1xx.c
* @author MCD Application Team
* @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_stm32f1xx_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_stm32f1xx_xx.s" file, to
* configure the system clock before to branch to main program.
*
* 4. The default value of HSE crystal is set to 8 MHz (or 25 MHz, depending on
* the product used), refer to "HSE_VALUE".
* 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.
