BITFIELDTYPEDEFAULTDESCRIPTION
7-0WAVFORM7[7:0]R/W0When the GO bit is asserted, the waveform processing engine will go to register address 0x03 and play the waveform ID that is indicated there. After completion of that waveform, the engine proceeds to register address 0x04 to play that waveform ID. If the ID value is zero, the playback process terminates. Otherwise this process repeats until it finds a waveform ID of zero, or all 8 waveforms are played.
