Research direction
Start at the ITMSettings::bus_id entry point and compare its current behavior and documentation with the permitted values in the ARMv7-M standard, page 718. Confirm the supported bus IDs and update the relevant check or documentation so the API matches the standard; verify the existing ITM-related tests if available.
