/* pause/resume present difficulties for the NRF PWM audio module.
*
* A PWM sequence can be stopped in its tracks by sending a TASKS_STOP event,
* but there's no way to pick up the sequence where it was stopped; you could
* start at the start of one of the two sequences, but especially for "single buffer"
* sample, this seems undesirable.
*
* Or, you can stop at the end of a sequence so that you don't duplicate anything
* when restarting, but again this is unsatisfactory for a "single buffer" sample.
*
* For now, I've taken the coward's way and left these methods unimplemented.
* Perhaps the way forward is to divide even "single buffer" samples into tasks of
* only a few ms long, so that they can be stopped/restarted quickly enough that it
* feels instant. (This also saves on memory, for long in-memory "single buffer"
* samples, since we have to locally take a resampled copy!)

//| :mod:`audiopwmio` --- Support for audio input and output
//| ========================================================
//|
//| .. module:: audiopwmio
//| :synopsis: Support for audio output via digital PWM
//| :platform: NRF52
//|
//| The `audiopwmio` module contains classes to provide access to audio IO.
//|
//| Libraries
//|
//| .. toctree::
//| :maxdepth: 3
//|
//| PWMAudioOut
//|
//| All classes change hardware state and should be deinitialized when they
//| are no longer needed if the program continues after use. To do so, either
//| call :py:meth:`!deinit` or use a context manager. See
//| :ref:`lifetime-and-contextmanagers` for more info.
//|
//| Since CircuitPython 5, `Mixer`, `RawSample` and `WaveFile` are moved
//| to :mod:`audiocore`.
