= 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 nonstable; that is, it will not persist whenpreset and clear inputs
return to their inactive (high) level.
