		The WDT can be enabled at reset. This is controlled by the WDTAUTO
		fuse. The WDT will be set in basic mode, RCSYS is set as source for
		CLK_CNT, and PSEL will be set to a value giving Tpsel above 100 ms
		(SAM4L)

		This setting informs that start-up logic that the watchdog is
		enabled.

	---help---
		If the WDT can be enabled at reset then this setting may be used to
		configure and disable the watchdog timer very early in the boot
		sequence.
