 		 #180065 - 0ns hold is allowed indeed...
Responding to: ???'s previous message
... but are you sure it's not a negative time, "fixed" by adding the extra capacitance of the analyzer? You might try to zoom in to that area, and also try to capture timing of start, stop and the reverse data direction (slave-to-master).
