Accessing FX2 Full/Empty FIFOs

Version 1
    Question: What happen if the external master tries to read from an Empty FIFO or write to a full FIFO of the FX2 operating in slave FIFO mode. Will the Fx2 just ignore the write/read?



    The external master must avoid reading from an empty FIFO or writing to a full FIFO.  Doing so will result in FIFO pointers going out of synch and the FIFOs being rendered unusable. The external master can use the FIFO full/empty flag to monitor the state of the FIFO and decide when to stop writing/reading to/from the FIFO.
