Writing a non-zero value to these bits enables the Window mode, and selects the duration of the closed period accordingly.

The bits are optionally lock-protected:

• If LOCK bit in WDT.STATUS is '1', all bits are change-protected (Access = R)
• If LOCK bit in WDT.STATUS is '0', all bits can be changed (Access = R/W)

Writing a non-zero value to this bit enables the WDT, and selects the time-out period in Normal mode accordingly. In Window mode, these bits select the duration of the open window.

The bits are optionally lock-protected:

• If LOCK in WDT.STATUS is '1', all bits are change-protected (Access = R)
• If LOCK in WDT.STATUS is '0', all bits can be changed (Access = R/W)
