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;
q = lower case letters indicate the state of the referenced output one set-up time prior to the LOW-to-HIGH
CP transition;
X = don’t care;
↑ = LOW-to-HIGH CP transition.
