DON'T do this one. Neither the reset nor the arduino bootloader does not reset the watchdog
That's a bit strong given the fact that it's fairly easy to shut off the watchdog at the top of setup.
But it's not.
Ah. Got it. I'm using an Arduino compatible board that doesn't have this problem. I assumed all boards behaved like mine.
It may be possible to avoid this problem by using the "Interrupt and System Reset Mode". It all depends on how the processor behaves if the watchdog is turned off in the ISR.
