See Section 26.1 “DC Characteristics: Supply Voltage” for specifications.
The Power-up Timer is decoupled from Brown-out Reset, allowing these features to be independently controlled.
Unimplemented: Read as ‘0’
BORV<1:0>: Brown-out Reset Voltage bits
11 = V
10 = V
01 = V
00 = V
BOREN<1:0>: Brown-out Reset Enable bits
11 = Brown-out Reset enabled in hardware only (SBOREN is disabled)
10 = Brown-out Reset enabled in hardware only and disabled in Sleep mode
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
1 = PWRT disabled
0 = PWRT enabled
Unimplemented: Read as ‘0’
WDTPS<3:0>: Watchdog Timer Postscale Select bits
1111 = 1:32,768
1110 = 1:16,384
1101 = 1:8,192
1100 = 1:4,096
1011 = 1:2,048
1010 = 1:1,024
1001 = 1:512
1000 = 1:256
0111 = 1:128
0110 = 1:64
0101 = 1:32
0100 = 1:16
0011 = 1:8
0010 = 1:4
0001 = 1:2
0000 = 1:1
WDTEN: Watchdog Timer Enable bit
1 = WDT is always enabled. SWDTEN bit has no effect
0 = WDT is controlled by SWDTEN bit of the WDTCON register
