The clock configuration tab displays a graphic that enables easy visualisation and comprehension of the clock routing and configuration, as well as a graphical editing interface that provides instant feedback and validation of the options selected:

  • Invalid clock values are highlighted in red

  • Tooltips provide the information necessary to correct an invalid configuration

  • Radio buttons allow easy clock selection

  • Drop down lists are used to select between valid divider values

STM32CubeMX automatically generates the system, CPU and AHB/APB bus frequencies from the clock sources and prescalers selected by the user.
