//| until it is listed in an `alarm`-enabling function, such as `alarm.sleep_until_alarm()` or
//| `alarm.restart_on_alarm()`.
//|
//| :param pins: The pins to monitor. On some ports, the choice of pins
//| 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 all_same_value: If ``True``, all pins listed must be at `value` to trigger the alarm.
//| If ``False``, any one of the pins going to `value` will trigger the alarm.
//| :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 value opposite
//| 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.
