Clock ¶
This interface enables microcontroller clock configuration and management, offering two view modes:
Graphic view: Provides a schematic overview of the clock paths, clock sources, dividers, and multipliers(see Clock tree).
Drop-down menus and buttons allow modification of clock element values.
A zoom feature is available to enhance visibility.
Table view: Displays all clock sources in a tabular format (see Clock table).
In both views, users can:
Switch view (1): Switch between clock tree or table view.
Search (2): Search for specific clock components.
Resolve clock issues (3): Address any existing clock issues.
Conflicts are highlighted with red borders.
Reset clock (4): Reset the clock configuration to default settings.
Lock/unlock (5): Lock an element to prevent changes. It is possible to lock any type of clock element (for example, multiplexers, dividers, etc.)
Toggle detail view (6): Display or hide the detail view panel.
The following functionalities are only available in the clock tree:
Configure RCC (7): Navigate to the RCC configuration tab.
Highlight clock path (8): Visually emphasize the selected clock path.
Highlight all paths: Highlight all related paths.
Highlight occurrences: Highlight every occurrence of the selected element.
Highlight to origin: Highlight the path tracing back to its origin source.
The following functionalities are only available in the graphic view:
Navigation and zoom controls (9): The bottom toolbar provides tools for zooming (see Clock tree toolbar).
Keyboard shortcuts (10): Access a list of available shortcuts to speed up operations within the graphic view (see Clock tree shortcuts).
The following functionalities are only available in the table view:
Columns table settings (11): Customize visible table columns.
Pagination controls (12): Navigate through the table pages.
Note
When no issues are detected in the clock view, the Resolve clock issues button changes to No clock issues .
Clock tree ¶
Clock tree toolbar ¶
To toggle between the hand cursor (move mode) and the selection cursor (edit mode), user can press the Esc key , which makes it easier to pan the graph and then quickly return to selecting and editing graph elements.
Clock tree shortcuts ¶
Clock table ¶
Note
If you enter an invalid frequency for the selected clock sources, a message indicates that the current clock configuration does not provide a valid solution. You can change the clock source or keep the current configuration.
When you enter a value that is not within the acceptable limits for the system, a notification appears stating:
