    How can I know the packet end of an OUT transfer from GPIF side

    liu.ming

      For an in transfer(cyusb -> host), I can notiy usb3014 the packet end by using PKTEND# signal;

         

      But for an out transfer(host -> cyusb), can I know the packet end from GPIF side if I using dma to transfer data from UIB to GPIF? Is FIFO_EMPTY ok?
