H = HIGH voltage level steady state.
L = LOW voltage level steady state.
h = HIGH voltage level one setup time prior to the LOW-to_HIGH clock transition.
l = LOW voltage level one setup time prior to the LOW-to-HIGH clock transition.
X = Don’t care.
q = Lowercase letters indicate the state of the referenced output prior to the LOW-to-HIGH clock transition.
↑ = LOW-to-HIGH clock transition.
