H = High level (steady state).
L = Low level (steady state).
X = Irrelevant.
↑ = Transition from low to high level.
↓ = Transition from high to low level.
Q0 = The level of Q before the indicated input conditions were established.
Toggle: Each output changes to the complement of its previous level on each active transition (pulse) of the clock.
* This configuration is unstable; that is, it will not persist when preset and clear inputs return to their inactive (high)
level.
