7:Src/system_stm32f0xx.c **** * 1. This file provides two functions and one global variable to be called from

12:Src/system_stm32f0xx.c **** *
13:Src/system_stm32f0xx.c **** * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
14:Src/system_stm32f0xx.c **** * by the user application to setup the SysTick
15:Src/system_stm32f0xx.c **** * timer or configure other parameters.
16:Src/system_stm32f0xx.c **** *
17:Src/system_stm32f0xx.c **** * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
18:Src/system_stm32f0xx.c **** * be called whenever the core clock is changed
19:Src/system_stm32f0xx.c **** * during program execution.
20:Src/system_stm32f0xx.c **** *
21:Src/system_stm32f0xx.c **** * 2. After each device reset the HSI (8 MHz) is used as system clock source.
22:Src/system_stm32f0xx.c **** * Then SystemInit() function is called, in "startup_stm32f0xx.s" file, to
23:Src/system_stm32f0xx.c **** * configure the system clock before to branch to main program.
24:Src/system_stm32f0xx.c **** *
25:Src/system_stm32f0xx.c **** * 3. This file configures the system clock as follows:
