H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state;
 = LOW-to-HIGH clock transition;  = HIGH-to-LOW clock transition.
Q6S = the data in register stage 6 before the LOW to HIGH clock transition.
Q7S = the data in register stage 7 before the HIGH to LOW clock transition.
