//| """Support for edge counting
//|
//| The `countio` module contains logic to read and count edge transitions
//|
//| For more information on the applications of counting edges, see
//| `this Learn Guide on sequential circuits
//| <https://learn.adafruit.com/digital-circuits-4-sequential-circuits>`_.
//|
//| 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."""
