ing from Deep Sleep functionally looks like a POR, the
technique described in Section 9.2.4.9 “Checking
and Clearing the Status of Deep Sleep Mode”
should be used to distinguish between Deep Sleep and
a true POR event.
When a true POR occurs, the entire device, including
all Deep Sleep logic (Deep Sleep registers, RTCC,
DSWDT, etc.) is reset.
