The actions of the GO bit directly follow the IN/TRIG pin. When the IN/TRIG pin is high, the GO bit is high. When the IN/TRIG pin goes low, the GO bit clears. Therefore, a falling edge cancels the transaction. The level trigger can implement a GPIO-controlled buzz on-off controller if an appropriately long waveform is selected. The user must hold the IN/TRIG high for the entire duration of the waveform to complete the effect.
