the necessary precautions, if appropriate.
CE Declaration of Conformity
The system should be powered down when not in use.
It is recommended that ESD precautions be taken when handling DSTREAM, RealView ICE, and RealView Trace
equipment.
The DSTREAM, RealView ICE, and RealView Trace modules generate, use, and can radiate radio frequency energy
and may cause harmful interference to radio communications. There is no guarantee that interference will not occur in
a particular installation. If this equipment causes harmful interference to radio or television reception, which can be

2.1 About DSTREAM
DSTREAM is an ARM®debug and trace hardware unit. It enables you to connect a software
debugger to an ARM processor-based target using a hardware interface such as JTAG or Serial
Wire Debug (SWD). It also enables the collection of trace from the device for non-intrusive
debug and code optimization.
Note
Some debuggers are unable to capture trace from the external trace port of a System-on-Chip
(SoC) device. See the documentation that accompanies your debugger for details of the trace
capabilities of your debugger.
