35.3.4 CRC Checking of Flash During Boot

Some devices support running a CRC check of the Flash contents as part of the boot process. This check can be performed even when the device is locked. The result of this CRC check can be read from the ASI_CRC_STATUS register. Refer to the CRCSCAN - Cyclic Redundancy Check Memory Scan section in the device data sheet for more information on this feature.
