Attention

This software is licensed under terms that can be found in the LICENSE file in the root directory of this software component. If no LICENSE file comes with this software, it is provided AS-IS.

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_stm32wb0x.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 (64 MHz) is used as system clock source. Then SystemInit() function is called, in "startup_stm32wb0x.s" file, to configure the system clock before to branch to main program.

This file configures the system clock as follows:

System Clock source | HSI

SYSCLK(Hz) | 16000000

HCLK(Hz) | 16000000
