# Burst Sequence Diagrams

## *DRSSTC\_Driver* Burst Sequence Example

The following sequence diagram shows a resonant burst operation (after the [loop has closed](/mujoseph-docs/emma-mk1-drsstc/drsstc_driver-firmware-overview/high-resolution-timer-hrtim/external-event-eev-configuration.md#eev6-zero-crossing-detection-zcd-feedback-signal)/ [ZCD feedback](/mujoseph-docs/emma-mk1-drsstc/hardware-overview/electrical-design/pcb-design/current-sense.md#zero-crossing-detection-zcd) detected) following an invocation of `mujoe_resdrv_start_burst`:
