H = High level (steady state).
L = Low level (steady state).
X = Irrelevant
= Transition from low to high level
Q0= The level of Q before the incicated steady
state input conditions were established.
*This configuration is nonstable; that is it will not persist
when preset and clear inputs return to their inactive (high) level.
