Legend:
R = Readable bit
R = Readable bit
P = Programmable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7,5
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
bit 6
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
device Reset
