8.5.8.2.6 Waveform Triggers
When the waveform sequencer has the effect (or effects) loaded, the waveform sequencer can be triggered by
an internal trigger, external trigger (edge), or external trigger (level). To trigger using the internal trigger set the
MODE[2:0] bit to 0 in register 0x01. To trigger using the external trigger (edge), set the MODE[2:0] bit to 1 and
then follow the trigger instructions listed in the Edge Trigger section. To trigger using the external trigger (level),
set the MODE[2:0] bit to 2 and then follow the trigger instructions listed in the Level Trigger section.
