Legend:
R = Readable bit
-n = Value at POR
P = Programmable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7,5
bit 6
bit 4
bit 3-0
FWDTEN<1:0>: Watchdog Timer Enable bits
11 = WDT is enabled in hardware
10 = WDT is controlled with the SWDTEN bit setting
01 = WDT is enabled only while the device is active; WDT is disabled in Sleep; SWDTEN bit is disabled
00 = WDT is disabled in hardware; SWDTEN bit is disabled
WINDIS: Windowed Watchdog Timer Disable bit
1 = Standard WDT is selected; windowed WDT is disabled
0 = Windowed WDT is enabled; note that executing a CLRWDT instruction while the WDT is disabled in
hardware and software (FWDTEN<1:0> = 00 and SWDTEN (RCON<5>) = 0) will not cause a
device Reset
FWPSA: WDT Prescaler bit
1 = WDT prescaler ratio of 1:128
0 = WDT prescaler ratio of 1:32
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
