bit 7 bit 0
Legend:
R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’
-n = Value when device is unprogrammed u = Unchanged from programmed state
bit 7-5 Unimplemented: Read as ‘0’
bit 4-3 BORV1:BORV0: Brown-out Reset Voltage bits
11 = VBOR set to 2.1V
10 = V
BOR set to 2.8V
01 = V
BOR set to 4.3V
00 = V
BOR set to 4.6V
bit 2-1 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
bit 0 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.
