4 Multiple trigger indications

Sending a trigger to external tools can have extra consequences apart from stopping trace capture.

For example, in cases where the events immediately before the trigger might be important, but only a small buffer is available. In this case, uploads to a host computer for decompression can occur, reducing the amount of trace data that is stored in the TPA. This procedure is also useful where the trigger originated from a device that is not directly associated with a trace source, and is a marker for a repeating interesting event.

The following figure shows multiple trigger indications from flushes.
