Use RWDT to force reboot if wake from deep sleep fails

[iParcelBox]

Hi,

Is there a way to enable RWDT and continue to feed it during deep sleep, so that the device will do a full hard reset (incl. RTC) in the event it fails to wake from deep sleep after a pre-defined period of time (e.g. 1 hour)?

Any code samples to point me in the right direction would be much appreciated!
