9:Core/Src/system_stm32f3xx.c **** * - SystemInit(): This function is called at startup just after reset and

11:Core/Src/system_stm32f3xx.c **** * the "startup_stm32f3xx.s" file.

12:Core/Src/system_stm32f3xx.c **** *
|

13:Core/Src/system_stm32f3xx.c **** * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
