Fx3 GPIF 5 bit mode

[Anonymous]

Hi:

   

    I have a board with an FX3 connected to an FPGA where the GPIF is the synchronous 2bit mode.but through reading "Slave FIFO Interface for EZ-USB® FX3™: 5-Bit Address Mode", I have a quetion about 5bit mode:

   

Q1: Is there an advantage to use gpif 5bit mode compared with 2bit mode?only can use more physical sockets?

        Hi, If you need data paths just less than 4 from the GPIF to any peripheral then please go for SlaveFIFO 2bit. But in case if you need more than 4 then please go for 5bit. Other than that there is no specific advantage or disadvantage. Thanks, sai krishna.

thanks for your answer! but what do you mean "data paths"? it means  sockets used for transmitting datas from GPIF to USB,UART,SPI,I2C and other peripheral?

Hi,

   

Yes. You are right.

   

Thanks,
