Can I trap a watchdog in the MKL17?

The MKL17 has a builtin watchdog but there doesn't appear to be any way to trap the watchdog event itself. The processor simply resets and I can read the RCM_SRS0[WDOG] bit to be set so on that next reset I can determine a watchdog occurred, but I'd like to generate a traceback and burn it into flash before resetting the unit. Is there anyway to configure the unit to do this or do I need an external watchdog?

 

Thanks.
