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<=1'b0;
else if(PRE == 1)
Q<=1'b1;
else
Q<=D;
end
