A low-to-high transition on the IN/TRIG pin sets the GO bit. The playback sequence indicated in the waveform sequencer plays as normal. The user can cancel the transaction by clearing the GO bit. An additional low-to-high transition while the GO bit is high also cancels the transaction which clears and resets the GO bit. Clearing the trigger pin (high-to-low transition) does nothing, therefore the user can send a short pulse without knowing how long the waveform is. The pulse width should be at least 1 µs to ensure detection.
