All sources of synchronization are combined before being used to generate synchronization in both trace streams, if data trace is active.
Periodic synchronization of the data trace stream is aligned with synchronization in the instruction stream. If the ETM is configured to trace only events in the data stream, it is also necessary to configure the instruction trace stream to contain sufficient elements to permit the required data trace stream synchronization.
