Unimplemented: Read as ’0’
WDTPS2:WDTPS0: Watchdog Timer Postscale Select bits
111 = 1:1
110 = 1:2
101 = 1:4
100 = 1:8
011 = 1:16

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
- n = Value when device is unprogrammed
U = Unimplemented bit, read as ‘0’
u = Unchanged from programmed state

bit 7-4
bit 3-2
bit 1
bit 0
Unimplemented: Read as ’0’
BORV1:BORV0: Brown-out Reset Voltage bits
11 = VBOR set to 2.5V
10 = VBOR set to 2.7V
01 = VBOR set to 4.2V
00 = VBOR set to 4.5V
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.
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.
