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.
