Abstract：Based on SPI bus，design controller to read and write the EEPROM.Detailedly describe the SPI bus working principle and register defination of controller.On the basis of application example，EEPROM read and write operation and timing are introduced.Through the compilatior of controller driver based on ARM processor，achieve read and write operation to the EEPROM.

and verify the correctness of the SPI bus interface design.
