= High voltage level
= Low voltage level
= High state must be present one setup time before the
Low-to-High transition of LEXX or EXX (XX=AB or BA)
= Low state must be present one setup time before the
Low-to-High transition of LEXX or EXX (XX=AB or BA)
= Low-to-High transition of LEXX or EXX XX = AB or BA
