The SPI boot loading process is similar to the loading process explained in Section 4.6.1.2.1, Loading a Boot Image From EEPROM, except that the image is read from a NOR flash. The data formats supported are also the same as in Section 4.6.1.2, I2C Loading Process. All the other loading processes that are detailed for I2C master mode work for the SPI boot mode, too.
