I want to start a USB3.0 design using FX3 CYUSB3014 32bit slave fifo mode. from the documentation I understand that CYUSB3014 only supports 16bit slave fifo and not 32bit but sometimes people refer to 32bit slave fifo.
My question: how can I use 32bit synchronous slafe fifo when doc. page 15 (http://www.cypress.com/?docID=50647) states that only 16pin are connected in slafe fifo mode.
CYUSB3014 does support slave fifo in 32 Bit synchronous / asynchronous mode. Many of our customers use 32 Bit sync Slave fifo in CYUSB3014.
I agree that the details on sync slavefifo in Page 15 creates an impression like oly 16 Bit interface can be used for slave fifo. We apologize for the confusion. We will change it in our next revision of the datasheet.

Thank you. This is what I wanted to hear.
