.. method:: Pin.init(mode, pull=Pin.PULL_NONE, af=-1)
.. method:: Pin.init(mode, pull=Pin.PULL_NONE, \*, value=None, alt=-1)
Initialise the pin:
- ``mode`` can be one of:
- *mode* can be one of:
- ``Pin.IN`` - configure the pin for input;
- ``Pin.OUT_PP`` - configure the pin for output, with push-pull control;

- ``Pin.AF_OD`` - configure the pin for alternate function, open-drain;
- ``Pin.ANALOG`` - configure the pin for analog.
- ``pull`` can be one of:
- *pull* can be one of:
- ``Pin.PULL_NONE`` - no pull up or down resistors;
- ``Pin.PULL_UP`` - enable the pull-up resistor;
- ``Pin.PULL_DOWN`` - enable the pull-down resistor.
- when mode is ``Pin.AF_PP`` or ``Pin.AF_OD``, then af can be the index or name
of one of the alternate functions associated with a pin.
- *value* if not None will set the port output value before enabling the pin.
- *alt* can be used when mode is ``Pin.AF_PP`` or ``Pin.AF_OD`` to set the
index or name of one of the alternate functions associated with a pin.
This arg was previously called *af* which can still be used if needed.
Returns: ``None``.
