MC7700 turning off with AT!PCOFFEN=1

IoT Modules MC/EM Series
1

Hi there!

I accidentally set AT!PCOFFEN=1 on a MC7700, and it seems like my computer is always setting W_DISABLE , because seemingly no matter what I do, I can’t bring back the serial interface that I would need to connect to, in order to restore factory settings.

Is there any way of restoring factory settings, out-of-band?

Cover the W_DISABLE pin (20) with a piece of tape. It’s an active low signal.

That’s such a practical solution, I don’t know why I didn’t think of it. Thanks! :slight_smile:
