Security bytes is possible

Poor connections.... Incorrect pin out.... Wrong oscilator setting... Leg lifting requied (use volt meter display) .. Secure part security bits required (AD) HC08 parts for example..

After all above can be certain is good try either Xprog or ETL...

hi!
I have reset failure. but connections ok
connections made as upa pinouts.
Could you send me pictures pinots of upa, or little help
I think the default is pinouts because reading is correct in eeprom
I would like your opinion.
sorry for my English
thanks

how I can find security bits?
thanks

Search dk for security bits by application..

If they can not be found and you have checked various options upa can not help you..

You will need ETL to work this out.. be sure mask is covered and remove part from board !

As for pin outs use upa help pdfs and switch to meter view to check for possible legs that might require lifting..

ok
i am going to try it
thanks
