7 | * This file provides two functions and one global variable to be called from
8 | * user application:
9 | * - SystemInit(): This function is called at startup just after reset and
10 | * before branch to main program. This call is made inside
11 | * the "startup_stm32l0xx.s" file.
12 | *
13 | * - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
14 | * by the user application to setup the SysTick
15 | * timer or configure other parameters.
16 | *
17 | * - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
18 | * be called whenever the core clock is changed
19 | * during program execution.
