*
|

* The file is the unique include file that the application programmer

|

* - Configuration section that allows to select:
|
||||
* - The STM32H7xx device used in the target application
|
||||
* - To use or not the peripheral’s drivers in application code(i.e.
|
||||
* code will be based on direct access to peripheral’s registers
|
||||
* rather than drivers API), this option is controlled by
|
||||
* "#define USE_HAL_DRIVER"

|

*
|

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

* constant and the selected clock source:
|
||||
*
|

* - If SYSCLK source is CSI, SystemCoreClock will contain the CSI_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.

* (**) HSI_VALUE is a constant defined in stm32h7xx_hal.h file (default value
