 Every SPI-compatible device has the SS (Slave Select) input that enables communication in this specific device. Master is responsible for generating this enable signal – separately for every slave in the system, as present in figure {{ref>RefSPIPic1}}. Every SPI-compatible device has the SS (Slave Select) input that enables communication in this specific device.

 Due to different hardware implementations, there are four SPI protocol operation modes (table {{ref>RefSPITab2}}). The mode used in the master must fit the mode implemented in the slave device. Due to different hardware implementations, there are four SPI protocol operation modes (table {{ref>RefSPITab2}}).
