ep8 and fifo out
We are developing a usb project with Cy7c68013A-100. We have heavy input traffic and light output traffic. So we dicided to use ep2 as input endpoint and ep8 as output.
But we can't get output data from the fifo pins (FD0 - FD15). FIFOADDR is set to "11". FLAG is signaling like data is going through.
Then we turn things upside down and set ep2 as output endpoint and ep8 as input. And the data appears on the fifo pins, so everything works well.
Does it mean that we can't use ep8 as output endpoint, or we missed something significant?
