WIZ107SR/WIZ108SR Rev 1.4 external watchdog reset - HINT

Just for those who face the problem that WIZ107SR/WIZ108SR resets periodically every 2 seconds with custom application code:
with board revision 1.4 an external watchdog was added: TPS3823-33 must be fed by a level transition on Port 2.0

Thanks for your advice.
