In the hunt for the big fat penguin jumping all over the bus, I have managed to lock my MSP34xx in some sort of test mode. Read returns the register number we just wrote, not the contents. It doesn't apply to the revision code registers, though. Seems to be non-volatile, power cycle did no good. It may have gone wrong because I did not sent reset_on and reset_off as two separate messages - there was no Stop between the two. -- Kyösti Mälkki kmalkki@xxxxxxxxx
