* 1. This file provides two functions and one global variable to be called from

* - SystemInit(): This function is called at startup just after reset and
* before branch to main program. This call is made inside
* the "startup_stm32f3xx.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_stm32f3xx.s" file, to
* configure the system clock before to branch to main program.
*
* 3. This file configures the system clock as follows:
*=============================================================================
* Supported STM32F3xx device
*-----------------------------------------------------------------------------
* System Clock source | HSI
*-----------------------------------------------------------------------------
* SYSCLK(Hz) | 8000000

* - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*)

* (*) HSI_VALUE is a constant defined in stm32f3xx_hal.h file (default value

* in voltage and temperature.
*
* (**) HSE_VALUE is a constant defined in stm32f3xx_hal.h file (default value
