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.
Figure 94: Synchronous acceptor input trigger
Output characteristics:
• In addition to trigger events from other trigger objects, the digio.trigger[N].assert() and
tsplink.trigger[N].assert() functions release the line if the line is latched low. The pulse
width is not used.
• When the trigger is asserted, it releases the line if the line is latched low.
• The physical line state does not change until all drives (internal and external) release the line.
• Action overruns occur if the internal drive is not latched low and a source event is received.
