Code

module jk_ff_enable (
    input  CLK,
    input  EN,
    input  J,
    input  K,
    output reg Q
);
// Write your code here
    always @(posedge CLK) begin
        if (EN) begin
            case ({J, K})
                2'b00: Q <= Q;       // hold
                2'b01: Q <= 1'b0;    // reset
                2'b10: Q <= 1'b1;    // set
                default: Q <= ~Q;    // toggle
            endcase
        end
    end
