PFL with S4 and MAXii

Hi Pete

And thank you for your reply.

I don't believe that I have this issue cause it happens to work well.

In fact, I believe that I have a timing issue somewhere.

When I stated that the MAXii PFL design does nothing, I meant that, possibly, it has considered that the S4 simply needs nothing.

That was the purpose of my question regarding the sample timing diagram.

I assume that the PFL design monitors the configuration wires and would decide to start or not the cfg cycle.

This is my missing info.

I will start to simulate, but I do not know if this would work as the AN states that one can not.....

Regards

Thomas
