//| `alarm.exit_and_deep_sleep_until_alarms()`.
//|
//| :param microcontroller.Pin pin: The pin to monitor. On some ports, the choice of pin
//| may be limited due to hardware restrictions, particularly for deep-sleep alarms.
//| :param bool value: When active, trigger when the pin value is high (``True``) or low (``False``).
//| On some ports, multiple `PinAlarm` objects may need to have coordinated values
//| for deep-sleep alarms.
//| :param bool edge: If ``True``, trigger only when there is a transition to the specified
//| value of ``value``. If ``True``, if the alarm becomes active when the pin value already
//| matches ``value``, the alarm is not triggered: the pin must transition from ``not value``
//| to ``value`` to trigger the alarm. On some ports, edge-triggering may not be available,
//| particularly for deep-sleep alarms.
//| :param bool pull: Enable a pull-up or pull-down which pulls the pin to the level opposite
//| that of ``value``. For instance, if ``value`` is set to ``True``, setting ``pull``
//| to ``True`` will enable a pull-down, to hold the pin low normally until an outside signal
//| pulls it high.
