Reading microcontroller MC68HC908JL8

Hello Experts.

Please help in reading the ROM microcontroller MC68HC908JL8.

In the MON08 its firmware can only write and erase, read, makes requests ss code.

Please tell me whether it is possible to define it?

I would be grateful for any advice.

Best Regards

Vladimir

The MON08 firmware is fixed and cannot be changed

Thank you.

You want to say that I would not consider it a controller? I managed podprat one code E8 05 FF FF E8 54 E3 BA and was able to keep the firmware. Just picked up a long time, helped programmer Orange. The opportunity is there, but I do not know the definition of code pattern.

Determine the SS-code for reading the ROM

Hello,

you should read the section in the datasheet about the security code to get an overview what you are going to do.

There is no official way to get the security Bytes from a secured microcontroller and in a Freescale Forum definitely nobody would tell you how to crack a Freescale MCU if it is possible.
