-  *      - SystemInit(): This function is called at startup just after reset and

-  *                      before branch to main program. This call is made inside

-  *                      the "startup_stm32l0xx.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.

-  *

-  *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**)
