About tracing with DSTREAM

DSTREAM is capable of capturing trace data into a cyclic buffer, and you can define the buffer size up
to a maximum of 4GB.
When a sufficient amount of trace data has been captured to fill the buffer, the FULL LED illuminates.
The buffer then wraps, continues to capture trace data, and overwrites the original trace data captured.
You can stop trace capture by using a trigger condition or a manual stop, and you can configure the
amount of trace captured after a trigger event.
See the DS-5 debugger documentation for details of the trace capabilities, and for configuring trace.
