D Flip-Flop with Clock Enable and Asynchronous Clear
When clock enable (CE) is High, and asynchronous clear (CLR) is Low, the data on the data input (D) of FDCE is transferred to the corresponding data output (Q) during the Low-to-High clock (C) transition. When CLR is High, it overrides all other inputs and resets the data output (Q) Low. When CE is Low, clock transitions are ignored.
