Conformance Notices
This section contains conformance notices.
Federal Communications Commission Notice
This device is test equipment and consequently is exempt from part 15 of the FCC Rules under section 15.103 (c).
Class A
Important: This is a Class A device. In residential areas, this device may cause radio interference. The user should take
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
determined by turning the equipment off or on, you are encouraged to try to correct the interference by one or more of
the following measures:
• ensure attached cables do not lie across the target board
• reorient the receiving antenna
• increase the distance between the equipment and the receiver

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.
