Is there an example for the slave sync fifo that uses 5-bit addressing?
We do have example for Slave Sync Fifo 5bit addressing. It comes along with GPIF 2 designer (http://www.cypress.com/?rID=59628). You can refer the state diagram from the same, and the firmware side you can refer SlaveFifoSync example coming as part of FX3 SDK (http://www.cypress.com/?rID=57990).
example firmware that supports 5-bit addressing mode will be added in the new SDK release that is going to happen in a weeks time.
