 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Under what circumstances does the MM.watchdog flag get cleared or reset to zero? |

On a restart (for whatever reason). Geoff Graham - http://geoffg.net |

Maybe a misunderstanding. I understand that MM.Watchdog is true on a restart due to the watchdog timer but on what conditions is the flag set back to zero? GM |

It is set to zero when the uM starts with a normal power up and it is set to true if a watchdog timeout caused the restart. It is not changed until the next power up. Currently a reset (pulling MCLR low) does not change MM.Watchdog, it requires a power recycle (I plan to change this). Are you seeing something different? Geoff Geoff Graham - http://geoffg.net |

Thanks for the info Geoff all is as you have explained. I am accessing the micromite remotely (via the console port) and would like to reset the MM.watchdog flag but as you have explained I will need to power cycle the micromite. GM |
