Legend:
R = Readable bit
P = Programmable bit
-n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state

bit 2-1
bit 0
Unimplemented: Read as ‘0’
VREGEN: USB Internal Voltage Regulator Enable bit
1 = USB voltage regulator enabled
0 = USB voltage regulator disabled
BORV1:BORV0: Brown-out Reset Voltage bits⁽¹⁾
11 = Minimum setting
.

.
00 = Maximum setting
BOREN1:BOREN0: 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 21.0 “Electrical Characteristics” for the specifications.
2: The Power-up Timer is decoupled from Brown-out Reset, allowing these features to be independently
controlled.
