H = HIGH Level (steady state), L = LOW Level (steady state)
X = Irrelevant (any input, including transitions)
↑ = Transition from LOW-to-HIGH level.
QAO, QBO, QHO = the level of QA, QB, or QH, respectively, before the indi-
cated steady state input conditions were established.
QAn, QGn = The level of QA or QG before the most recent ↑ transition of the
clock; indicated a one-bit shift.
