Finding the
Answer
As you look at the overlapping waveforms, you notice there are transitions
on the data lines during the read, indicating the data is unstable, which is
the probable cause of the problem you’ve been looking for.
You have found what is causing the problem in this routine. Additional
troubleshooting of the hardware will lead you to the actual cause.
Summary You have just learned how to use the timing and state analyzers
interactively to find a problem that first appeared to be a software
problem, but actually is a hardware problem.
You have learned to:
• trigger one analyzer with the other
• time correlate measurement data
• interpret the Mixed mode display
• overlap timing waveforms
