Toggle Flip-Flop with Toggle Enable and Asynchronous Preset

When the asynchronous preset (PRE) input is High, all other inputs are ignored and output Q is set High. When toggle enable input (T) is High and PRE is Low, output Q toggles, or changes state, during the Low-to-High clock (C) transition.
