    FX2LP Slave FIFO full and empty change simultaneously

    dan.morgan

      i'm using the slave FIFO interface for bulk auto-in transfers directly from an FPGA to the host, in asynchronous mode.

         

       

         

      Right after the FULL flag asserts, the FULL flag deasserts and the EMPTY flag asserts simultaneously.

         

       

         

      I have attached a screen shot of the waveforms.

         

       

         

      Any ideas of what could cause this?
