Referenz design SPI Interface

I need to use the SPI interface of my Zynq to control the AD9234 interface. When analyzing the design (for example zc706 and daq2) there are spi0_csn_i and spi0_sdo_i input signals, why? For SPI I need SDI, SDO, SCLK and CSN. Why are they defined as input and output?


Also what ps_interrupt signals do I need?
