Hi ,

The clklow is been explained in the page no: 363 of the below document.

This signal should be used with Intel external soft lock detection logic.

That's a direct quote from the user guide, but I don't think this answers the question. Where is the external soft lock detection described? Google doesn't show any reference for an Intel soft lock circuit.
