    What happens to data if the host fails to read it on time?

    naz

      Here's the scenario: the GPIF generates the data and passes it through the manual DMA channel to the USB side. The data generation is non-stop, so if the host is not reading the data, what happens to it, at what stage, and is there a way to signal when it happens (via events/interrupts)? Please, provide the detailed description of data flow from the GPIF unit to USB unit including all the events/interrupts, buffers, buffer wrap ups, buffer commitments and other events that happen during the transfer.
