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.
See descriptions below

STOP
bit is 0, the Stop Mode Recovery is not caused by a WDT timeout. This bit is
