bit 2-1
bit 0
Unimplemented: Read as ‘0’
BORV<1:0>: Brown-out Reset Voltage bits⁽¹⁾
11 = Minimum setting
.
.
.
00 = Maximum setting
BOREN<1:0>: Brown-out Reset Enable bits⁽²⁾
11 = Brown-out Reset enabled in hardware only (SBOREN is disabled)
10 = Brown-out Reset enabled in hardware only and disabled in Sleep mode
(SBOREN is disabled)
01 = Brown-out Reset enabled and controlled by software (SBOREN is enabled)
00 = Brown-out Reset disabled in hardware and software
PWRTEN: Power-up Timer Enable bit⁽²⁾
1 = PWRT disabled
0 = PWRT enabled
Note 1: See Section 27.1 “DC Characteristics” for the specifications.
2: The Power-up Timer is decoupled from Brown-out Reset, allowing these features to
be independently controlled.
Legend:
R = Readable bit
P = Programmable bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state
