Complex and Internal Triggers
6.6
TRIGGER TYPE SELECTION
Up to four events can be required before the trace or break occurs. The combination of
these events can be specified three ways:
In addition, the complex triggering feature along with the trace memory window can be
used to perform the following functions:
6.6.1
Sequential
Figure 6-2 shows the Trigger subtab of the Complex Trigger Settings tab for Sequential
event selection.
1. Select Sequential if each event must occur in sequence to generate the trigger.
2. Click on a tab to enter information about each event ( Event 1 , Event 2 , Event 3 )
and the trigger event ( Trigger ).

Keep in mind that for sequential triggers, the emulator will wait until Event 1 is satisfied
before proceeding to Event 2 , and on down to the final Trigger event. If only one trigger
event is specified and it is placed in Event 1 , extra instruction cycles will be executed
while the emulator determines that Event 2, Event 3 and the Trigger event have been
satisfied. Therefore, always right-justify the trigger specification; that is, use the
right-most event tabs first.
