Legend:
R = Readable bit
-n = Value at POR
CO = Clearable Only bit
W = Writable bit
‘1’ = Bit is set
r = Reserved bit
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-5
bit 4
bit 3
bit 2
bit 1
bit 0
Unimplemented: Read as ‘0’
Reserved: Maintain as ‘0’
VDDBOR: VDD Brown-out Reset Flag bit⁽¹⁾
1 = A VDD Brown-out Reset has occurred (set by hardware)
0 = A VDD Brown-out Reset has not occurred
VDDPOR: VDD Power-On Reset Flag bit^(1,2)
1 = A VDD Power-up Reset has occurred (set by hardware)
0 = A VDD Power-up Reset has not occurred
VBPOR: VBPOR Flag bit^(1,3)
1 = A VBAT POR has occurred (no battery connected to the VBAT pin, or VBAT power below Deep Sleep
Semaphore retention level, set by hardware)
0 = A VBAT POR has not occurred
VBAT: VBAT Flag bit⁽¹⁾
1 = A POR exit has occurred while power applied to the VBAT pin (set by hardware)
0 = A POR exit from VBAT has not occurred
Note 1:
2:
3:
This bit is set in hardware only; it can only be cleared in software.
Indicates a VDD POR. Setting the POR bit (RCON<0>) indicates a VCORE POR.
This bit is set when the device is originally powered up, even if power is present on VBAT. It is recom-
mended that the user clear this flag, and the next time, this bit will only set when the VBAT voltage goes
below 0.4-0.6V with VDD = 0.
