That agrees with what Martin Josefsson and i came across, we ended up combing through the datasheet and ended up coming to the conclusion that either we were missing something subtle or the hardware just didn't work. It's a shame because i had a friend who had a whole bunch of these and wanted to use the watchdog in production.
