The hard processor system (HPS) provides two serial peripheral interface (SPI) masters and two SPI slaves.
The SPI masters and slaves are instances of the Synopsys
(SSI) controller (DW_apb_ssi). †

Features of the SPI Controller

The SPI controller has the following features: †
• Serial master and serial slave controllers – Enable serial communication with serial-master or
serial-slave peripheral devices. †
• Serial interface operation – Programmable choice of the following protocols:
• Motorola SPI protocol
• Texas Instruments Synchronous Serial Protocol
• National Semiconductor Microwire
• DMA controller interface integrated with HPS DMA controller
• SPI master supports received serial data bit (RXD) sample delay
• Transmit and receive FIFO buffers are 256 words deep
• SPI master supports up to four slave selects
• Programmable master serial bit rate
• Programmable data item size of 4 to 16 bits
• Support for Multi-master mode through the FPGA logic
