Description of the example

The device is put to sleep in sleep modes with increasing "depth", and is periodically woken up by the RTT_ALARM. The RTT_ALARM wakes the CPU every 5 seconds. The device will remain in ACTIVE mode for approximately 3 seconds after wake- up, before it goes to sleep in the next mode.

A pin (LED_ACTIVITY_STATUS_PIN) with, e.g., a LED connected is driven low when the device is active and driven high when the device is sleeping.
