To further what Eric said, to answer the question which requirements are important in the standard, they ALL are.

Every sentence and requirement that was written in the standard is there for a reason and was the result of much discussion. I can't stress the importance of reading the standard closely and following the details.

Please do not rely on 3rd party documentation like the Enttec manual for determining requirements. By doing that, at best, you'll only be compatabile with their product.

Another point worth mentioning, the Enttec Sniffer is a great debugging tool, but do NOT rely on it's analysis of the timing. We have found that it is frequently incorrect in regards to doing detailed timing analysis. For that, you're best bet is using an Oscilloscope.
