50 1) by calling CMSIS function SystemCoreClockUpdate()
51 2) by calling HAL API function HAL_RCC_GetSysClockFreq()
52 3) each time HAL_RCC_ClockConfig() is called to configure the system clock frequency
53 Note: If you use this function to configure the system clock; then there
54 is no need to call the 2 first functions listed above, since SystemCoreClock
55 variable is updated automatically.
