To exit XIP mode, software should first disable the DAC and INDAC to ensure no new data read accesses will be sent to the FLASH device. It should then set mode bits to other than the established in the corresponding Flash Device specifications. These are dependent on the FLASH device and manufacturer. Software should then reset OSPI_CONFIG_REG[17] ENTER_XIP_MODE_FLD.
Note the FLASH device must see a READ instruction before it can disable its internal XIP mode state, so this means XIP mode will internally stay active until the next READ instruction is serviced. User must take care to ensure that XIP mode is disabled before the end of any READ sequence.
