South edge, east end (input, bit width 1) Asynchronous reset: When 0 or undefined, this input has no effect.Īs long as it is 1, the flip-flop's value is pinned to 0.
East edge, south end (output, bit width 1) Outputs the complement of the value currently stored by theįlip-flop. East edge, labeled Q, north end (output, bit width 1) Outputs the value currently stored by the flip-flop.
