H = High voltage level.
h = High voltage level one set-up time prior to the low-to-high clock transition.
l = Low voltage level one set-up time prior to the low-to-high clock transition.
L = Low voltage level.
X = Don’t care.
­↑ = Transition from low to high level.
qn = Lower case letters indicate the state of the reference output clock transition.
