//| """Light and deep sleep used to save power
//|
//| The `sleepio` module provides sleep related functionality. There are two supported levels of
//| sleep, light and deep.
//|
//| Light sleep leaves the CPU and RAM powered so that CircuitPython can resume where it left off
//| after being woken up. Light sleep is automatically done by CircuitPython when `time.sleep()` is
//| called. To light sleep until a non-time alarm use `sleepio.sleep_until_alarm()`.
//|
//| Deep sleep shuts down power to nearly all of the chip including the CPU and RAM. This can save
//| a more significant amount of power at the cost of starting CircuitPython from scratch when woken
//| up. CircuitPython will enter deep sleep automatically when code exits without error. If an
//| error causes CircuitPython to exit, error LED error flashes will be done periodically. To set
//| alarms for deep sleep use `sleepio.set_alarms` they will apply to next deep sleep only."""
