	always @* begin
        if(EN) begin
            if (S && R) begin
                Q_reg = 1'b0;
                Qn_reg = 1'b1;
            end else if(S && !R) begin
                Q_reg = 1'b1;
                Qn_reg = 1'b0;
            end else if (!S && R) begin
                Q_reg = 1'b0;
                Qn_reg = 1'b1;
            end
