— — — — WDTPS2 WDTPS1 WDTPS0 WDTEN
bit 7 bit 0
bit 7-4 Unimplemented: Read as ’0’
bit 3-1 WDTPS2:WDTPS0: Watchdog Timer Postscale Select bits
111 = 1:1
110 = 1:2
101 = 1:4
100 = 1:8
011 = 1:16
010 = 1:32
001 = 1:64
000 = 1:128
bit 0 WDTEN: Watchdog Timer Enable bit
1 = WDT enabled
0 = WDT disabled (control is placed on the SWDTEN bit)
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 bit 0
bit 7-4 Unimplemented: Read as ’0’
bit 3-2 BORV1:BORV0: Brown-out Reset Voltage bits
11 = V
BOR set to 2.5V
10 = V
BOR set to 2.7V
01 = V
BOR set to 4.2V
00 = V
BOR set to 4.5V
bit 1 BOREN: Brown-out Reset Enable bit
(1)
1 = Brown-out Reset enabled
0 = Brown-out Reset disabled
Note: Enabling Brown-out Reset automatically enables the Power-up Timer (PWRT),
regardless of the value of bit PWRTEN
. Ensure the Power-up Timer is enabled any
time Brown-out Reset is enabled.
bit 0 PWRTEN
: Power-up Timer Enable bit
(1)
1 = PWRT disabled
0 = PWRT enabled
Note: Enabling Brown-out Reset automatically enables the Power-up Timer (PWRT),
regardless of the value of bit PWRTE
. Ensure the Power-up Timer is enabled any
time Brown-out Reset is enabled.
