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, 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.
