This is a forum for Coldfire chips, which are "MCF5xxxx". That chip is a DSP. You should post in the DSP forum.

https://community.nxp.com/t5/Digital-Signal-Controllers/bd-p/dsc

Your problem has nothing to do with the chip though. You need the User or Service Manuals for your elevator. That should detail a command which says to save the changed into non-volatile memory, assuming the board has that somewhere. There might be a small EEPROM or it might use the internal 4k of Data Flash inside the CPU.

Something like this (Google found this for the DCD-231)

http://www.sigmaelevator.com/updata/pds/ELCOM_PA_08_3.pdf

In the "Examples" section it finishes off with:

(h) Key in ‘BBB’ and ‘39E’ to go [S39] menu to save new data.
(i) Key in ‘AAE’ and ‘1E’ in sequence. Then, the new data is saved.

Your one should have a similar command, maybe the same.

Thanks for replying 

I have manual for Elevator and I do every thing good 

But my problem is not show directly after once time power off 

Maybe I turn power off and on 10 times and I don't lost configuration or maybe after 4 turn on and off the configuration automatically changes 

The problem maybe in pwoer (vdd,vdda,vss,visa,or vcapc)?

I need solve this problem I have this problem 4 board it in used about 10 year ago 

Thanks for help my
