0: Data register not empty, writing to the data register may cause losing a conversion value.
1: Data register for channel B is empty, meaning that a new channel input data may be written.
0: Data register not empty, writing to the data register may cause losing a conversion value.
1: Data register for channel A is empty, meaning that a new channel input data may be written.
0: No underrun in channel B has occurred.
1: Underrun has occurred, at least two consecutive trigger events were received without any new incoming data on channel B in
the meantime.
0: No underrun in channel A has occurred.
1: Underrun has occurred, at least two consecutive trigger events were received without any new incoming data on channel A in
the meantime.
