-  ******************************************************************************
-  * @file    system_stm32l4xx.c
-  * @author  MCD Application Team
-  * @version V1.1.1
-  * @date    29-April-2016
-  * @brief   CMSIS Cortex-M4 Device Peripheral Access Layer System Source File
-  *
-  *   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_stm32l4xx.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.
-  *
-  *   After each device reset the MSI (4 MHz) is used as system clock source.
-  *   Then SystemInit() function is called, in "startup_stm32l4xx.s" file, to
-  *   configure the system clock before to branch to main program.
-  *
-  *   This file configures the system clock as follows:
-  *=============================================================================
-  * System clock source                | PLL_HSE                     | PLL_HSI           | PLL_MSI
-  *                                    | (external 4 to 48 MHz xtal) | (internal 16 MHz) | (internal 100kHz to 48 MHz)
-  *---------------------------------------------------------------------------------------------
-  * SYSCLK(MHz)                        | 48                          | 80                | 80
-  *---------------------------------------------------------------------------------------------

-  *---------------------------------------------------------------------------------------------
-  * APB1CLK (MHz)                      | 48                          | 80                | 80
-  *---------------------------------------------------------------------------------------------
-  * APB2CLK (MHz)                      | 48                          | 80                | 80
-  *---------------------------------------------------------------------------------------------
-  * USB capable (48 MHz precise clock) | YES                         | NO                | YES

-  *         be used by the user application to setup the SysTick timer or configure
-  *         other parameters.
-  *
-  * @note   Each time the core clock (HCLK) changes, this function must be called
-  *         to update SystemCoreClock variable value. Otherwise, any configuration
-  *         based on this variable will be incorrect.
-  *
-  * @note   - The system frequency computed by this function is not the real
-  *           frequency in the chip. It is calculated based on the predefined
-  *           constant and the selected clock source:
-  *
-  *           - If SYSCLK source is MSI, SystemCoreClock will contain the MSI_VALUE(*)
-  *
-  *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(**)
-  *
-  *           - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(***)
-  *
-  *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(***)
-  *             or HSI_VALUE(*) or MSI_VALUE(*) multiplied/divided by the PLL factors.
-  *
-  *         (*) MSI_VALUE is a constant defined in stm32l4xx_hal.h file (default value
-  *             4 MHz) but the real value may vary depending on the variations
-  *             in voltage and temperature.
-  *
-  *         (**) HSI_VALUE is a constant defined in stm32l4xx_hal.h file (default value
-  *              16 MHz) but the real value may vary depending on the variations
-  *              in voltage and temperature.
-  *
-  *         (***) HSE_VALUE is a constant defined in stm32l4xx_hal.h file (default value
-  *              8 MHz), user has to ensure that HSE_VALUE is same as the real
-  *              frequency of the crystal used. Otherwise, this function may
-  *              have wrong result.
