More watchdog ?'s

2005-07-29 by Bruce Parham

If fig 28, on pg. 53 of the 'M128 data sheet, is true it look like the wd timer
is running all the time and, to insure a full count, a wdr should be issued
prior to enabling. Is this really the case or is the timer held in reset when
not enabled? Thanks.

I've never put that one to the test, but it seems reasonable and painless to
do so.  I've always issued a WDR before enabling the WDT.
