Still not making yourself clear. The use of that code is to reset the timer that causes the watchdog to reboot the microcontroller.. developer.mbed.org/.../WatchDog-Timer Are you sure a watchdog timer is the best option to solve your need?

The watchdog must be configured before it is started. After it is started, the watchdog’s configuration registers, which comprise registers CRV, RREN, and CONFIG, will be blocked for further configuration.

If you need to reconfigure WDT after it's started, you should instead look into using the RTC.
