Well, it is not how to setup the wdt, it is how to implement it.  For
example I have about 30 functions in my program.  If there is a wdt
restart I would like to go back to where I was before without effecting
the program flow and recover variable values.  So the software would
continue where it was as if nothing happened.

I'm not sure if I am answering the question you are asking, but here is
an example from CCS C docs:

main() {
   setup_wdt(WDT_2304MS);
   while (TRUE) {
         restart_wdt();
         perform_activity();
   }
}

This sets up the WDT to reset every 2.304 seconds, and you just call
restart_wdt() to reset it whenever needed.
