2.6. Triggering

A trigger event indicates points of interest. The STM supports triggering functionality through

  • assertion of the trigger outputs, TRIGOUTSPTE, TRIGOUTSW, and TRIGOUTHETE

  • insertion of TRIG or TRIG_TS packets into the trace stream

  • use of the trigger ATID on the ATB interface.

See the System Trace Macrocell Programmers’ Model Architecture Specification for more information about triggers.
