Hi,

First off, many thanks for helping me my question "How to check if an input
gets stuck?"

Now I need to do CRC check on ROM as well. I will also have to do RAM check.

I will ask about CRC first.

I already understand how CRC works and have a routine to calculate a 16-bit
number's CRC.

But I don't know how to apply the routine to check the program ROM and data
ROM. (I use a small chip 12CE519.)

Can someone shrede lights on it?

Some code to illustrate the process will be greatly appreciated!

Thanks!
Tony
