Instrumentation Trace Macrocell (ITM) support
Hard real-time debugging requires close interaction with the processor. Tracing shall provide a chronological picture of a system's inner workings up to, starting from or in the vicinity an event, mainly to guide a human in understanding a faulty program. Arm and Cortex microcontroller can provide trace event messages via Instrumentation Trace Messages (ITM).
The Universal Debug Engine can visualize the output messages in a trace log view.
