D Flip-Flop with Synchronous Reset and Synchronous Set
FDRS is a single D-type flip-flop with data (D), synchronous set (S), and synchronous reset (R) inputs and data output (Q). The synchronous reset (R) input, when High, overrides all other inputs and resets the Q output Low during the Low-to-High clock (C) transition. (Reset has precedence over Set.) When S is High and R is Low, the flip-flop is set, output High, during the Low-to-High clock transition. When R and S are Low, data on the (D) input is loaded into the flip-flop during the Low-to-High clock transition.
