The Card Status Register (CSR) transmits the card’s status information (which may be
stored in a local status register) to the host. The CSR is defined in Section 4.10.1 in the
SDA Physical Layer Specification, Version 2.00.
The SD Status Register (SSR) contains status bits that are related to iNAND proprietary
features and may be used for future applications. The SD Status structure is described in
Section 4.10.2 in the SDA Physical Layer Specification, Version 2.00.
The 16-bit Relative Card Address (RCA) Register carries the card address published by
the card during the card identification. Refer to Section 5.4 in the SDA Physical Layer
Specification, Version 2.00 for more information.
The SD Card Configuration Register (SCR) is in addition to the CSD Register. The SCR
provides information about special features in SanDisk iNAND. For more information,
refer to Section 5.6 in the SDA Physical Layer Specification, Version 2.00.
All registers are accessible in SPI Mode. Their format is identical to the format in the SD
Bus Mode, however a few fields are irrelevant in SPI Mode. In SPI Mode, the Card Status
Register has a different, shorter, format as well. Refer to Section 7.4 in the SDA Physical
Layer Specification, Version 2.00. for more details.
In general, a file system provides structure for iNAND data. The SD Card File System
Specification, published by the SD Association, describes the file format system
implemented in the SanDisk iNAND.
