|
- *
|
|
|
- * 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_stm32f4xx.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.
