Legend:
R = Readable bit
U = Unimplemented bit
W = Writable bit
P = Programmable bit
-n = Bit Value at POR: (‘0’, ‘1’, x = Unknown)
r = Reserved bit

bit 1
bit 0
Reserved: Write ‘0’; ignore read
ON: Watchdog Timer Enable bit⁽¹⁾
1 = Enables the WDT if it is not enabled by the device configuration
0 = Disable the WDT if is was enabled in software.
Reserved: Write ‘0’; ignore read
SWDTPS<4:0>: Shadow Copy of Watchdog Timer Post-Scaler Value from Device Configuration bits
Reserved: Write ‘0’
WDTCLR: Watchdog Timer Reset bit
1 = Writing a ‘1’ will reset the WDT.
0 = Software cannot force this bit to a ‘0’.
Note 1: A read of this bit will result in a ‘1’ if the WDT is enabled by the device configuration or by software.
