Configures and controls transfers through the ITM interface
| ITMENA | Enables the ITM |
| TSENA | Enables Local timestamp generation |
| SYNCENA | Enables Synchronization packet transmission for a synchronous TPIU |
| TXENA | Enables forwarding of hardware event packet from the DWT unit to the ITM for output to the TPIU |
| SWOENA | Enables asynchronous clocking of the timestamp counter |
| STALLENA | Stall the PE to guarantee delivery of Data Trace packets. |
| TSPRESCALE | Local timestamp prescaler, used with the trace packet reference clock |
| GTSFREQ | Defines how often the ITM generates a global timestamp, based on the global timestamp clock frequency, or disables generation of global timestamps |
| TRACEBUSID | Identifier for multi-source trace stream formatting. If multi-source trace is in use, the debugger must write a unique non-zero trace ID value to this field |
| BUSY | Indicates whether the ITM is currently processing events |
