WebThe circuit waits for an event on clk or clr, then sets q3 and q4 to 0 if clr is 1 or 0, respectively. Otherwise, the circuit sets either q3 or q4 to the value d, depending on whether a posedge clk activated the third Always Construct, or a negedge clk activated the fourth Always Construct. The fifth Always Construct is sensitive to clk and pre.
