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.
• When the trigger is asserted, it generates a low pulse that is similar to the Falling Edge trigger
mode
