Constants
---------
.. data:: DAC.NORMAL
NORMAL mode does a single transmission of the waveform in the data buffer,
.. data:: DAC.CIRCULAR
CIRCULAR mode does a transmission of the waveform in the data buffer, and wraps around
to the start of the data buffer every time it reaches the end of the table.
