|

* 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:

* 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.
