3. Set the edge or glitch for each channel.
Don't cares are indicated by a (.).
NOTE:
After you close the edge term assignment dialog, you may see $ indicators in
the term value field. This symbol indicates that the value can't be displayed in
the selected base. Choose Binary base to see the actual assignments.
Using Timer Terms
Timers are like other resource terms in that they are either true or
false. They are unlike other terms, however, in that they are controlled
within the trigger sequence and act like a stopwatch. When a timer
reaches its assigned count (expires), it becomes true. When a timer
expires or stops, its count resets to zero.
Timers can be set to Start, Stop, Pause, or Continue as the analyzer
enters a trigger sequence level. The two timers are global, so each
sequence level except the first has the ability to control the same timer.
As more sequence levels are added, the timer status in the new levels
defaults to Off. If a timer is paused in one level, it must be continued in
another level before it will be restarted. If the trigger sequence returns
to the same sequence level again, the timer will be restarted.
Each Timer term can be used by either of the two analyzers, but not
both.
To Assign a Time Value to the Timer Terms
1. Select the Timer subtab in the Trigger tab.
2. Select the timer value field, next to the timer name.
3. Enter a timer value.
4. Use the up/down arrow buttons to scroll through timer values.
The minimum value a timer can have is 400 ns, which is also the default
value.
To Include a Timer in a Trigger Sequence
1. Assign a time value to the timer you want to use.
2. Select the sequence level you want to use it in, and choose Edit....
