Hello,
Is it possible to throttle a streaming transfer from host to device? In other words, can the device hold off the host?
Regards,
Rob

Hi,
If you set NAK on your endpoint, it will throttle the transfer and make sure the host is informed about it.

Hi Madhu
I have an FPGA hanging off the GPIF interface. I'd like the FPGA to hold-off the host, if needed. Is this possible? How does one NAK on this interface?

Hi,
You can have an interrupt (GPIO) from the FPGA to FX3. When FPGA asserts this interrupt pin, FX3 may set the NAK on the endpoint using the interrupt callback
