80. DFF with Async Reset and Preset

How do you plan to solve it?

module dff_async_reset_preset (
    input  CLK,
    input  RST,
    input  PRE,
    input  D,
    output reg Q
);
    always @(posedge CLK or posedge RST or posedge PRE) begin
        if ( RST == 1) 
            Q <= 0;
        else if (PRE == 1 )
            Q <= 1;
        else 
            Q <= D;
    end
