Each trigger mode controls the input trigger detection and output trigger generation. The input
detector monitors for and detects all edges, even if the node that generates the output trigger causes
the edge.
A trigger overrun generates if an input trigger is received before the previous input trigger processes.
To determine if a trigger overrun has occurred, reference the trigger overrun attributes.
For additional information on the hardware trigger modes, see
command reference
To have direct control of the line state, use the bypass trigger mode.
