The AXI Serial Peripheral Interface (SPI) connects to the Advanced eXtensible Interface (AXI4). This core provides a serial interface to SPI devices such as SPI EEPROMs and SPI serial flash devices. The SPI protocol, as described in the Motorola M68HC11 data sheet, provides a simple method for a master and a selected slave to exchange data. This 32-bit soft IP core is designed to interface with the AXI4-Lite interface.

Key Features

• AXI4-Lite interface is based on the AXI4 specification
• Connects as a 32-bit AXI4-Lite slave
• Supports four signal interface (MOSI, MISO, SCK and SS)
• Supports slave select (SS) bit for each slave on the SPI bus
• Supports full-duplex operation
• Supports master and slave SPI modes
• Supports programmable clock phase and polarity
• Supports continuous transfer mode for automatic scanning of a peripheral
