Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-1

Unimplemented: Read as ‘0’

bit 0

SWDTEN: Software Enable or Disable the Watchdog Timer bit(1)

1 = WDT is turned on

0 = WDT is turned off (Reset value)
