SLOS854D May 2014 – March 2018 DRV2605L
This bit is used to fire processes in the DRV2605L device. The process fired by the GO bit is selected by the MODE[2:0] bit (register 0x01). The primary function of this bit is to fire playback of the waveform identifiers in the waveform sequencer (registers 0x04 to 0x0B), in which case, this bit can be thought of a software trigger for haptic waveforms. The GO bit remains high until the playback of the haptic waveform sequence is complete. Clearing the GO bit during waveform playback cancels the waveform sequence. Using one of the external trigger modes can cause the GO bit to be set or cleared by the external trigger pin. This bit can also be used to fire the auto-calibration process or the diagnostic process.
