bit 7

bit 0

bit 7-5

Unimplemented: Read as ‘0’

bit 4-3

BORV1:BORV0: Brown-out Reset Voltage bits(1)

= Maximum setting

= Minimum setting

bit 2-1

BOREN1:BOREN0: Brown-out Reset Enable bits(2)

= Brown-out Reset enabled in hardware only (SBOREN is disabled)

= Brown-out Reset enabled in hardware only and disabled in Sleep mode

(SBOREN is disabled)

= Brown-out Reset enabled and controlled by software (SBOREN is enabled)

= Brown-out Reset disabled in hardware and software

bit 0

PWRTEN: Power-up Timer Enable bit(2)

= PWRT disabled

= PWRT enabled

Note 1: See Section 26.1 “DC Characteristics: Supply Voltage” for 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

U = Unimplemented bit, read as ‘0’

-n = Value when device is unprogrammed

u = Unchanged from programmed state
