-  *
-  *   This file provides two functions and one global variable to be called from 
-  *   user application:
-  *      - SystemInit(): This function is called at startup just after reset and 
-  *                      before branch to main program. This call is made inside
-  *                      the "startup_stm32f4xx.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.
