I have a little problem and I don´t know exactilly if you can help me but I have to try because at this moment I’m lossed.
We’re developing a new product and in our first discussions with homologation institutes they have said to us that our software has to be necessary “SOFT- Class C”. This kind of software is very special because demands to the programmer a lot of considerations about the security of microprocessor.
This soft demands me to control CPU registers ( with WALPAT routines for example), Programme counter ,addressing, clock, invariable memory internal or external (cyclic redundancy test->CRC8) , timer , etc.
My question is:
¿Do you have developed any routines or libraries which control some possibles CPUs errors , clock errors or memory errors, etc? Is there any application note with some kind of questions?
Let me know please. I have to develop this project with the micro MC9S08AW16.
