The DRV2625 internal waveform sequencer can be triggered by controlling the IN/TRIG pin. There are two external trigger options: edge trigger and level trigger. See the data sheet for more information on these Input Trigger Modes.

In Mode 0 in the Additional Hardware Modes section, the DRV2625 can be set in external trigger mode and then triggered by using the trigger button control on button B4 or alternatively by applying an external trigger signal to the PWM test point.
