Hello !!

Thanks for your tip Craig !!

Im using a Siemens microcontroller
called SAB80C515-A in my application.

I have a comment to Craig's tip !!
Using a timer to create the reset code for the watchdog timer, doesent seem like a secure method. Imagine that your program stops because of waiting for a hardware signal that never occurs.
e.g. While(!P4.0); and P4.0 is never set !!
The interrupt from the timer will still reset the WDT, but your program still halts in the while loop.
Is this theory wrong ???

Best regards Brian.
