* @brief CMSIS Cortex-M7 Device Peripheral Access Layer System Source File.
|
||||
*
|
||||
* 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_stm32f7xx.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.

* (*) HSI_VALUE is a constant defined in stm32f7xx_hal_conf.h file (default value
