Unformatted text preview: FACE Primitive : D Flip Flop with Clock Enable and Asynchronous Clea Introduction This design element is a single D - type 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 this design element is transferred to the corresponding data output (@ ) during the Low - to - High clock ( C ) transition . When CLR is High It overrides all other Inputs and resets the data output ( ) Low . When CE Is Low , clock transitions are Ignored This flip flop is asynchronously cleared , outputs Low , when power is applied For FAGA devices , power - on conditions are simulated when global set reset GSR ) is active GSR defaults to active - High but can be inverted by adding an Inverter In front of the GSR input of the appropriate STARTUP architecture symbol Logic Table Inputs Outputs CLR CE No Change...

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
