HIGH voltage level
HIGH voltage level one setup time prior to the LOW-to-HIGH transition of nLEXX or nEXX (XX = AB or BA)
LOW voltage level
LOW voltage level one setup time prior to the LOW-to-HIGH transition of nLEXX or nEXX (XX = AB or BA)
Don’t care
LOW-to-HIGH transition of nLEXX or nEXX (XX = AB or BA)
No change
