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.

Synchronous acceptor trigger mode (SynchronousA)
Use the synchronous acceptor trigger mode (SynchronousA) with the SynchronousM trigger mode.
The roles of the internal and external drives are reversed in the SynchronousA trigger mode.
Input characteristics:
•
The falling edge is detected as the external drive pulses the line low, and the internal drive
latches the line low.
