Hi,

In FX3, how to configure the GPIF II for slave FIFO 8 bit operation.

Thanks

Subbarao.

GPIF II Designer has the "Data bus width" option to select 8 bit bus.

Regards,

Anand

 Hi,

Thanks for you reply.

I will select "Data bus witdth" as 8 bit in GPIF II designer.

In addition to Data bus width, in SlaveFifoSync example, io_cfg.isDQ32Bit  and  io_cfg.lppMode variables are assigned as below to select either 16 bit or 32 bit operation.

#if (CY_FX_SLFIFO_GPIF_16_32BIT_CONF_SELECT == 0)

    io_cfg.isDQ32Bit = CyFalse;

    io_cfg.lppMode   = CY_U3P_IO_MATRIX_LPP_UART_ONLY;

#else

    io_cfg.isDQ32Bit = CyTrue;

    io_cfg.lppMode   = CY_U3P_IO_MATRIX_LPP_DEFAULT;

#endif

here my doubt is which values I should assign to  io_cfg.isDQ32Bit  and  io_cfg.lppMode variables  for 8 bit operation.

Thanks,

Subbarao.

You should be going with the configuration similar to 16-bit bus.

Cheers,

Anand

 Hi Anand,

Thanks for the clarification.
