+ * This file provides two functions and one global variable to be called from

+ * - 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:

+ * 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.

+ * value for HSE crystal.
