使用FPGA发送数据到FX3时全标志设置为低

我用UB3.0做我的相机系统。现在我遇到了一个问题。当我使用FPGA发送数据到FX3时，我发现全标志设置为低，MMEDMA缓冲区已满。但我不想这样，如果我在PC中读取数据足够快，那么这个标志是否可能被设置为低。总之，我想要一个不间断的数据传输，但是完整的标志阻止了我。

   I‘m using u***3.0 to do my camera system. Now I meet a problem. when I use FPGA transmit data to FX3, I find the full flag is set to low which meens DMA buffer is full. But I don't want this, if I read data fast enough in PC, could it be possible that this flag is not set to low. In a word, I want a ceaseless data transfer, but the full flag stop me.
