Author

MCD Application Team This file provides two functions and one global variable to be called from user application:

SystemInit(): This function is called at startup just after reset and before branch to main program. This call is made inside the "startup_stm32h7xx.s" file.

SystemCoreClock variable: Contains the core clock (HCLK), it can be used by the user application to setup the SysTick timer or configure other parameters.

  - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
                             be called whenever the core clock is changed
                             during program execution.
