WebSo when @valid_count is 1, @fifo_rd_en will be high because @valid_count isn't 2. But @valid_count won't reach the value of 2, because @rd_en prevents it from that by staying high. So the data flows with both @fifo_rd_en and @rd_en held high, and @valid_count remaining on 1. Except for the beginning, the data is copied from @fifo_dout to @dout.
