5. Move the cursor to the [d] resource term and press INSERT three times . Three resource terms are added
which maybe used to define an ORed relationship to the triggerterm . The NEXT[] and PREV[ ]keys are
used to select a specific resource term for each field . The fields provide an ORed relationship for the
final trigger term as shown in figure 4-29 .

Figure 4-30. State Trace Specification With Sequence Terms and
ORed Trigger Starts Terms
Sequence triggering occasionally requires a restart term to ensure the sequence is found in one pass through
a branch network . If a restart term is not specified, the analyzer may eventually see all the sequence terms,
though not in the path specified, and a trace will be executed . If the logic analyzer finds part of the sequence
terms but not all the terms, then finding a sequence restart term will instruct the analyzer to repeat the
sequence until all terms are found in the specified sequence .
1 . Move the cursor to the sequence restart field.
2. Press NEXT[] or PREV[] to select a restart term .
3. As many as four resource terms may be selected to be ORed with the initial restart term by pressing the
INSERT key. The State Trace Specification (figure 4-31) contains the maximum amount of resource
terms to be ORed.
