I recommend NOT messing with the watchdog for any unrelated functions.

The function of the watchdog should be reserved for auch systems who
need it to implement security related functions; messing with it in
unrelated places (like setting it into unexpected states and or
timeouts) may cause undefined behaviour on such systems.

Don't do it.

Best regards,

Wolfgang Denk
