/* The SystemCoreClock variable is updated in three ways:
    1) by calling CMSIS function SystemCoreClockUpdate()
    2) by calling HAL API function HAL_RCC_GetSysClockFreq()
    3) each time HAL_RCC_ClockConfig() is called to configure the system clock frequency
       Note: If you use this function to configure the system clock; then there
             is no need to call the 2 first functions listed above, since SystemCoreClock
             variable is updated automatically.
