Use CyU3PGpifWriteDataWords with DMA AUTO channel
I'm now using FX3 as an 8080 master and GPIF works at DMA auto mode. It works well. Now I need to add a feature that some data can be sent by CyU3PGpifWriteDataWords through EP0 request. However, I added the condition in GPIFII state machine, but the control request always fails when call CyU3PGpifWriteDataWords in the setup request handler. What should I do?
