9.7.3. Multiple trigger indications

Sending a trigger to external tools can have additional 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, uploads to a host computer for decompression can occur, therefore reducing the amount stored in the TPA. This 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. Figure 9.3 shows multiple trigger indications from flushes.
