*
* - SystemCoreClock variable: Contains the core clock, it can be used

*
* - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
* be called whenever the core clock is changed

1) by calling CMSIS function SystemCoreClockUpdate()
2) by calling HAL API function HAL_RCC_GetHCLKFreq()
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.

*
* @note - The system frequency computed by this function is not the real

*
* - If SYSCLK source is CSI, SystemCoreClock will contain the CSI_VALUE(*)
* - 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 CSI_VALUE(*),
* HSI_VALUE(**) or HSE_VALUE(***) multiplied/divided by the PLL factors.
*
* (*) CSI_VALUE is a constant defined in stm32h7xx_hal.h file (default value
* 4 MHz) but the real value may vary depending on the variations

* in voltage and temperature.
*
* (***)HSE_VALUE is a constant defined in stm32h7xx_hal.h file (default value
