Im trying to use Watchdog Timer interrupt in R8C/tiny(RENESAS) micro

I couldn't get it.
Im getting the watchdog timer reset function and Iam trying to reset it
only once, even that i didn't get.
I made all settings. I don't know that interrupt function is not all
working.
Can I get any solution ....
The document states that you can only set PM12 to a logic one (select reset
mode) and there is no way to reset it from within the programme. Are you
wishing to use the interrupt or reset function?
You might find you need a write to both registers WDTR and WDTS (0x000D and
0x000E) to initialise and restart the watchdog count down.
Chapter 11 of the "RC8/10 Group Hardware Manual" describes it.
