//| """Support for frequency based protocols
//|
//| .. warning:: This module is not available in SAMD21 builds. See the
//|   :ref:`module-support-matrix` for more info.
//|

//| 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.
//|
//| For example::
//|
//|   import frequencyio
//|   import time
//|   from board import *
//|
//|   frequency = frequencyio.FrequencyIn(D13)
//|   frequency.capture_period = 15
//|   time.sleep(0.1)
//|
//| This example will initialize the the device, set
//| :py:data:`~frequencyio.FrequencyIn.capture_period`, and then sleep 0.1 seconds.
//| CircuitPython will automatically turn off FrequencyIn capture when it resets all
//| hardware after program completion. Use ``deinit()`` or a ``with`` statement
//| to do it yourself."""
