bit 7
bit 0
bit 7-5
bit 4-3
bit 2-1
bit 0
Unimplemented: Read as ‘0’
BORV1:BORV0: Brown-out Reset Voltage bits
11 = VBOR set to 2.1V
10 = VBOR set to 2.8V
01 = VBOR set to 4.3V
00 = VBOR set to 4.6V
BOREN1:BOREN0 Brown-out Reset Enable bits⁽¹⁾
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)
10 = Brown-out Reset enabled and controlled by software (SBOREN is enabled)
10 = Brown-out Reset disabled in hardware and software
PWRTEN: Power-up Timer Enable bit⁽¹⁾
1 = PWRT disabled
0 = PWRT enabled
Note 1: 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
