******************************************************************************
* @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.

* @brief Update SystemCoreClock variable according to Clock Register Values.

*
* @note - The system frequency computed by this function is not the real
* frequency in the chip. It is calculated based on the predefined
* constant and the selected clock source:
*
* - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*)
*
* - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(**)
*
* - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**)
* or HSI_VALUE(*) multiplied by the PLL factors.
*
* (*) HSI_VALUE is a constant defined in stm32f1xx.h file (default value
* 8 MHz) but the real value may vary depending on the variations
* in voltage and temperature.
*
* (**) HSE_VALUE is a constant defined in stm32f1xx.h file (default value
* 8 MHz or 25 MHz, depending on the product used), user has to ensure
* that HSE_VALUE is same as the real frequency of the crystal used.
* Otherwise, this function may have wrong result.
