Usage

<n>
Digital I/O trigger line (1 to 6)
Details
The event detector of a trigger enters the detected state when an event is detected. For the specified trigger line,
this command clears the event detector, discards the history, and clears the overrun status(sets the overrun
status to false).
For this command to function as expected, make sure you configure the trigger type and line state of the digital
line for use with the trigger model (use the digital line mode command).
Example
:TRIG:DIG2:IN:CLE
Clears the trigger event detector on I/O line 2.
