Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

bit 6-1

bit 0

WDTW: Watchdog Timer Window bit

1 = WDT count is in fourth quadrant

0 = WDT count is not in fourth quadrant

Unimplemented: Read as ‘0’

SWDTEN: Software Enable/Disable for Watchdog Timer bit(1)

1 = WDT is turned on

0 = WDT is turned off

Note 1: If the WDTEN Configuration bit = 1, then WDT is always enabled, irrespective of this control bit. If WDTEN

Configuration bit = 0, then it is possible to turn WDT on/off with this control bit.
