This content describes the Trace Port Interface Unit (TPIU) that is designed for use in single-processor systems based on Arm Cortex®-M processors. Using TPIU-M, you can export instrumentation trace data and processor execution trace data off-chip to a Trace Port Analyzer (TPA) for use in a software debugging environment, for example Arm Development Studio or Keil® Microcontroller Development Kit (MDK).
