 If the Toggle Watchdog C-Node is executed, the watchdog timer register is reloaded with the value given by the Enable Watchdog C-Node.\\
 If the watchdog timer register reaches zero before it is toggled the processor is reseted and the flashed program is booted and executed from start.\\

+Typically the "enable watchdog" is executed at program start and "toggle watchdog" is executed in the application main loop once on every iteration.\\

+**notes:**
+  * This c-nodes work on any target, but only in compiled mode
+  * Once the watchdog is enabled, debugging gets complicated. For this reason add the watchdog only at the very end of a development cycle
+  * If you need to survey several parallel loops, insert the "watchdog_toggle" into one loop and survey the loop counters of the others
+  * A reset during a file function can corrupt a file system
+  * When inserting the in line C-nodes the following warnings are generated.\\ This warning can be ignored, because it is about a disabled part of the block diagram. {{:snippets:errorsnwarnings:inline_c_node_not_supported.png?direct|}}
