Hi,Dears,

Should you tell me how to read the code in Mask MCU??

Or the code in Mask MCU could not read out???

Thanks.

Hi,

There really is not enough information to reply to your question properly. If you are talking about a masked rom part, you would only be able to read the mask if it is your own code.  If someone else owns the mask rom part, it would be proprietary.
