WDTEN<1:0>: Watchdog Timer Enable bits
11 = WDT is enabled in hardware; SWDTEN bit is disabled
10 = WDT is controlled by the SWDTEN bit setting
01 = WDT is enabled only while the device is active and is disabled in Sleep mode; SWDTEN bit is
disabled
00 = WDT is disabled in hardware; SWDTEN bit is disabled
