* @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_stm32g4xx.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 HSI (16 MHz) is used as system clock source.
|
||||
* Then SystemInit() function is called, in "startup_stm32g4xx.s" file, to
|
||||
* configure the system clock before to branch to main program.
|
||||
*
|
||||
* This file configures the system clock as follows:
