Because in China, there is no information that can be searched online, which is an opportunity to be recognized by the leadership, so I really want to succeed

Now, I read RXFIFO, always full status, I tried for a long time, two weeks, not too much time, hoping to get help, thanks

Sorry, but I don't have any technical expertise with the chip you are asking for help with.

From what I can find online, only the manual and a couple questions are available: http://www.cypress.com/taxonomy/term/81431

But, the questions refer to all hotlink products and not just the one that you are asking about.

My advice would be to open a case with the cypress technical support for help on it; They are very good with pointing you towards a solution or examples.

Go to the main cypress.com webpage -> Design Support -> Create a Support Case

Can you explain what you are having trouble with? It sounds like the chip is working as intended?

The chip looks like it is designed to work with HotLink devices; Try looking at some of those?

Sorry, we are in different time zones, my trouble is: my code is written according to the manual (asynchronous, on-chip FIFO, REFCLK18MHz), but the effect is not correct. So if someone can give me a program example, let me verify that this chip is genuine, because now look at the chip LOGO printing position is not the same, the feeling is not genuine.

At present, to complete the read and write FIFO communication, tx rx and spontaneous self-closing, FIFO interface to read the data through the parallel register, but read many Ox0505 / 0x0501 / 0x0301
