Enabling an event puts the device out of the low-power since the ADC autonomously samples to assert the event condition. + +IIO trigger support +=================== + +An IIO trigger ``ad4062-devX`` is registered by the driver to be used by the +same device, to capture samples to a software buffer. It is required to attach +the trigger to the device by setting the ``current_trigger`` before enabling +and reading the buffer. + +The acquisition is sequential and bounded by the protocol timings, software +latency and internal timings, the sample rate is not configurable. The burst +averaging mode does impact the effective sample rate, since it increases the +internal timing to output a single sample.
