clocks dynamically (i.e. without device restart) is no longer supported.
* ``set_dataset(..., save=True)`` has been renamed
``set_dataset(..., archive=True)``.
* On the AD9914 DDS, when switching to ``PHASE_MODE_CONTINUOUS`` from another mode,
use the returned value of the last ``set_mu`` call as the phase offset for
``PHASE_MODE_CONTINUOUS`` to avoid a phase discontinuity. This is no longer done
automatically. If one phase glitch when entering ``PHASE_MODE_CONTINUOUS`` is not
an issue, this recommendation can be ignored.

The "frequency update" pulse is sent to the DDS with a fixed latency
with respect to the current position of the time cursor.
When switching from other phase modes to the continuous phase mode,
there is no jump in the DDS phase. This is however not true when
using the continuous phase mode after playing back a DMA sequence
that contained the other phase modes.

:param pow: adds an offset to the phase.
:param phase_mode: if specified, overrides the default phase mode set

makes it easier to have a well-defined phase relationship between
DDSes on the same bus that are updated at a similar time.
