Hi team,

Could you tell me the solution when the I2C bus is stuck in low? I suppose that sending RESET or sending some clocks can resolve this issue. If yes, I'd like to know specific procedure.

Best Regards,

Hi Shoji,

I have not seen this situation before, thus not able to comment on a workaround, however I agree that toggling RESET should take the device out of an unknown state.
