D Flip-Flop with Asynchronous Preset
FDP is a single D-type flip-flop with data (D) and asynchronous preset (PRE) inputs, and data output (Q). The asynchronous PRE, when High, overrides all other inputs and presets the Q output High. The data on the D input is loaded into the flip-flop when PRE is Low on the Low-to-High clock (C) transition.
