Card Specific Data Register
The Card Specific Data (CSD) Register configuration information is required to access
iNAND data. The CSD defines the data format, error correction type, maximum data
access time, etc. The field structures of the CSD Register vary depending on the physical
specifications and card capacity. The CSD_STRUCTURE field in the CSD Register
indicates which structure version is used. Table 3-4 shows the version number as it relates
to the CSD structure. Refer to Section 5.3.1 of the SDA Physical Layer Specification,
Version 2.00 for more information.
Table 3-4
Table 3-5 provides an overview of the CSD Register. More field-specific information can
be found in Section 5.3.2, Table 5-4 of the SDA Physical Layer Specification, Version 2.00.
