The Reset Status (RSTSTAT) register is a read-only register which indicates the source of
the most recent Reset event, a Stop Mode Recovery event, and a WDT timeout. Reading
this register resets the upper 4 bits to 0.
This register shares its address with the Reset Status register, which is write-only 
(see
POR/VBO—Power-On initiated VBO Reset or general VBO Reset Indicator
If this bit is set to 1, a POR or VBO Reset event occurs. This bit is reset to 0, if a WDT
timeout or Stop Mode Recovery occurs. This bit is also reset to 0 when the register is read.
STOP—Stop Mode Recovery Indicator
If this bit is set to 1, a Stop Mode Recovery occurs. If the STOP and WDT bits are both set
to 1, the Stop Mode Recovery occurs because of a WDT timeout. If the STOP bit is 1 and
the
reset by Power-On Reset or WDT timeout that occurred while not in STOP mode. Reading
this register also resets this bit.
