WATCHDOG TIMER CONTROL REGISTER (WTIM)

DESCRIPTION
Prior to the Watchdog being enabled, this bit is known as WEN.
After the Watchdog is enabled, it is known as WTR. Once the
Watchdog timer has been enabled, this bit cannot be reset to 0.
As long as the Watchdog timer is enabled, it will indicate a '1'.
Writing a '1' to this bit causes the Watchdog to be retriggered to
the timer value indicated by bits WTM[3:0].
