run trace
Turning the count off allows the analyzer to store 1024 states
instead of 512 states. For example:
trace after 5c2h
only 5c2h
counting off <RETURN>
(The default trace depth is 256, which means that only 256 states
are uploaded and are available to be displayed. You can increase
the trace depth so that more states can be viewed; however, it takes
longer to upload more states. Refer to the "Changing the Trace
Depth" section in the "Displaying Traces" chapter.)
In the trace command, you can specify a trigger on the Nth
occurrence of a state. To specify an occurrence count, enter:
trace about 5c2h occurs 5
only 5c2h
counting state AGAIN <RETURN>
