|
|
|
9 * This file provides two functions and one global variable to be called from
|
|
|
10 * user application:
|
|
|
11 * - SystemInit(): This function is called at startup just after reset and
|
|
|
12 * before branch to main program. This call is made inside
|
|
|
13 * the "startup_stm32f4xx.s" file.
|
|
|
14 *
|
|
|
15 * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
|
|
|
16 * by the user application to setup the SysTick
|
|
|
17 * timer or configure other parameters.
|
|
|
18 *
|
|
|
19 * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
|
|
|
20 * be called whenever the core clock is changed
|
|
|
21 * during program execution.
