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.
