Problem fix/ Workaround
Do not ship products with on-chip debug of the tiny13 enabled.
5. Watchdog Timer Interrupt disabled
If the watchdog timer interrupt flag is not cleared before a new timeout occurs, the
watchdog will be disabled, and the interrupt flag will automatically be cleared. This is
only applicable in interrupt only mode. If the Watchdog is configured to reset the
device in the watchdog time-out following an interrupt, the device works correctly.
Problem fix / Workaround
Make sure there is enough time to always service the first timeout event before a
new watchdog timeout occurs. This is done by selecting a long enough time-out
period.
