Does anybody know to which register you should keep writing to keep the watchdog timer from resetting the system. The manuals say to write a register periodically to let the watchdog know that the system is fine, but from what I see in here there wasn't any accessible register generated from the SOPC builder.

Moreover, what is the generated name of this reset signal that is activated whenever the watchdog times out. And how can you monitor it. I know you cannot write to it or modify it, I just want to monitor it.

Any help will be appreciated.
