H = HIGH voltage level.
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition.
L = LOW voltage level.
l = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition.
q = lower case letters indicate the state of the referenced output one set-up time prior to the LOW-to-HIGH clock
X = don’t care.
