1.1 Event Triggering
For efficient development of USB systems, it is critical that users are able to extract
important information from a crowded stream of bus traffic, and accurately identify and
selectively record information that is of most interest. The Events and Action fields for
trigger set-up is intuitive and graphical, thus making pre-recording set-up time efficient.
USB Mobile HS provides real-time hardware triggering on the critical components of USB.
Users can custom-configure and control order of events selected for triggering. The count
and sequence options define the rules for data recording sessions. There are two
Counters, Filter Out/In and a Restart option that causes sequencing and counting to start
again. Any sequence can include up to seven events of any type.
Users can adjust the depth of the recording memory - up to 64 megabytes - and
determine where in the recording the trigger is located.
