See note 1.

Note

1. H = HIGH voltage level;

h = HIGH voltage level one set-up time prior to the LOW-to-HIGH CP transition;

L = LOW voltage level.

l = LOW voltage level one set-up time prior to the LOW-to-HIGH CP transition;

Z = high-impedance OFF-state;

X = don’t care;

↑ = LOW-to-HIGH CP transition.
