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 bit
11 = WDT is enabled in hardware
10 = WDT is controlled with the SWDTEN bit setting
01 = WDT is enabled only while 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 RCON bit, SWDTEN = 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
