• Pattern Trigger <For the setup procedure, see section 6.10>
With pattern triggers, the multiple trigger sources are set, and a trigger is activated
when all of the trigger conditions of the trigger sources are met or when the trigger
conditions are no longer met. Trigger conditions are specified by combining the status
(high or low) of each trigger source. In addition, one of the trigger sources can be set
to the clock signal, and the trigger can be activated in sync with the clock signal.
