*
* @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(**)

*
* (*) 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
