bit 7
Unimplemented: Read as ‘0’
ULPWUE: Ultra Low-Power Wake-up Enable bit
1 = Ultra Low-Power Wake-up enabled
0 = Ultra Low-Power Wake-up disabled
SBODEN: Software BOD Enable bit
1 = BOD enabled
0 = BOD disabled
WUR: Wake-up Reset Status bit
1 = No Wake-up Reset occurred
0 = A Wake-up Reset occurred (must be set in software after a Power-on Reset occurs)
Unimplemented: Read as ‘0’
POR: Power-on Reset Status bit
1 = No Power-on Reset occurred
0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
BOD: Brown-out Detect Status bit
1 = No Brown-out Detect occurred
0 = A Brown-out Detect occurred (must be set in software after a Brown-out Detect occurs)
Legend:
R = Readable bit
- n = Value at POR
