I'm trying to re-design old 68k board, replace MC68EC000 to MC68SEC000.
Only ROM data is available, no source code, then new board must be binary code compatible to old one.
I'm not sure, those software adjust timing by loop code.
Does 68SEC000 work same as 68EC000 in behavioral?
i.e. prefetch queue depth, latency clock for each instruction.
Are there any docs show those information?
