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 |
