Hi.
I'd like to implement slavefifo IN wih FPGA. then I've just found as below code from AN65974.
module slaveFIFO2b_fpga_top(
reset_in_, //input reset active low
clk, //input clp 27 Mhz
// sync,
fdata,
faddr, //output fifo address
slrd, //output read select
slwr, //output write select
flaga,
flagb,
flagc,
flagd,
sloe, //output output enable select
clk_out, //output clk 100 Mhz and 180 phase shift
slcs, //output chip select
pktend, //output pkt end
mode_p,
PMODE,
RESET,
// tri_state,
// PMODE_2 //used for debugging
);
But I'm not sure below 1 port what should I do with that
mode_p
Might be, I believe that above 1 port is connected with FX3 board. but I'm not sure and what am I supposed to with 1 port. Even there is nowhere in the CYPRESS documents about mode_p .
Does anyone know how to connect the mode_p with FPGA and FX3 board?

The mode_p are the input signals coming to the FPGA module. These 3 bit represent the mode in which you are configuring the FPGA to driver the data. If you see the AN65974, then you will notice the mention of sw8, these switches will select the mode for the slave fifo operation. For more details, you can refer the table provided in the application note, which shows the different supported mode.
