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