3 wire spi data transfer

Hi

I am using 3 wire SPI IP from the prime Software. I didn't found any document which says how to pass the data or how to use this IP.

In this IP,

Input side 3 wire SPI IP, which is Avalon memory mapped interface, consisting of data lines, clock, write, read, chipselect signals.

Output side 3 wire SPI IP, having SPI interface, consisting of MISO, MOSI, SS_N, SCLK.

I am using 5 slave to connect and communicate with 3 WIRE SPI.

CAN ANYONE HERE PLEASE TELL ME HOW TO PASS THE DATA OVER 3 WIRE SPI????
