+//|         """Create an alarm triggered by a `microcontroller.Pin` level. The alarm is not active
+//|         until it is passed to an `alarm`-enabling function, such as `alarm.light_sleep_until_alarms()` or
+//|         `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.
