completed when all stamples, from all shots, are acquired.
The @b{fsm-auto-start} attribute is read/write. It is used to activate the
auto-start acquisition option. We said that when an acquisition is over, the
ADC stops the state machine; if you write 1 in this attribute, the driver sends
a start command when the acquisition is over. This is useful for a streaming
acquisition because the driver starts the state machine automatically.
The ADC mark with a timestamp all these events: state machine start, state
machine stop and acquisition end. The device split each timestamp in 3
