NOTE
Use the SynchronousM trigger mode to receive notification when the triggered action on all nodes is
complete.
Input characteristics:
•
All rising edges are input triggers.
•
When all external drives release the physical line, the rising edge is detected as an input trigger.
•
A rising edge is not detected until all external drives release the line and the line floats high.

Output characteristics:
•
In addition to trigger events from other trigger objects, the
digio.trigger[
N
].assert()
and
tsplink.trigger[
N
].assert()
functions generate a low pulse that is similar to the falling
edge trigger mode.
•
An action overrun occurs if the physical line state is low while a stimulus event occurs.
