/*
* WDT_OPT_PAUSE_IN_SLEEP is a bit tricky because depending on
* the frequency the platform is running at and the wdog timeout
* value relative to the sleep time, the system may wakeup enough
* to keep system time accurate enough on timer rollovers. During
* this time, the wdog will start ticking again so you can
* possibly still have the wdog expire.
