Streaming traces over Arm ITM (ULINKpro version)

Percepio Application Note #21 describes the support for ITM tracing on ARM Cortex-M3, M4 and M7 MCUs that was introduced in Tracealyzer version 4.1. The ITM interface (short for Instrumentation Trace Macrocell) allows the Tracealyzer recorder library to send event data via the debug probe, either using the SWO pin (Serial Wire Output), or over the ETM trace pins if available.
