* @author MCD Application Team
* @version V1.1.1
* @date 29-April-2016
* @brief CMSIS STM32L4xx Device Peripheral Access Layer Header File.
*
* The file is the unique include file that the application programmer
* is using in the C source code, usually in main.c. This file contains:
* - Configuration section that allows to select:
* - The STM32L4xx device used in the target application
* - To use or not the peripheral<EFBFBD>s drivers in application code(i.e.
* code will be based on direct access to peripheral<EFBFBD>s registers
* rather than drivers API), this option is controlled by
* "#define USE_HAL_DRIVER"

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

* @brief Update SystemCoreClock variable according to Clock Register Values.
* The SystemCoreClock variable contains the core clock (HCLK), it can
* 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.
*
* - The result of this function could be not correct when using fractional
* value for HSE crystal.
