Register Information Within the card interface six registers are defined: OCR, CID, CSD, RCA, DSR and SCR. These can be accessed only by corresponding commands. The OCR, CID, CSD and SCR registers carry the card/content specific information, while the RCA and DSR registers are configuration registers storing actual configuration parameters. 1. OCR register The 32-bit operation conditions register stores the VDD voltage profile of the card. Additionally, this register includes status information bits.
2. CID Register The Card Identification (CID) register is 128 bits wide. It contains the card identification information used during the card identification phase. Every individual flash card shall have a unique identification number.
PSN The Serial Number is 32 bits of binary number. MDT The manufacturing date composed of two hexadecimal digits, one is 8 bit representing the year(y) and the other is four bits representing the month(m). The “m” field [11:8] is the month code. 1 = January. The “y” field [19:12] is the year code. 0 = 2000. As an example, the binary value of the Date field for production date “April 2001” will be: 00000001 0100. CRC CRC7 checksum (7 bits). 3.

CSD_STRUCTURE CSD structure version Card Capacity 0 CSD Version 1.0 Standard Capacity 1 CSD Version 2.0 High Capacity and Extended Capacity 2-3 reserved CSD Register Structure TAAC This field is fixed to 0Eh, which indicates 1 ms. The host should not use TAAC, NSAC, and R2W_FACTOR to calculate timeout and should uses fixed timeout values for read and write operations.
Note that for current SD Memory Cards that field must be always 0_0110_010b (032h) which is equal to 25MHz - the mandatory maximum operating frequency of SD Memory Card. In High-Speed mode, that field must be always 0_1011_010b (05Ah) which is equal to 50MHz. And when the timing mode returns to the default by CMD6 or CMD0 command, its value will be 032h. CCC The SD Memory Card command set is divided into subsets (command classes).
1 DSR implemented C_SIZE This field is expanded to 22 bits and can indicate up to 2 TBytes (It is the same as the maximum memory space specified by a 32-bit block address.) This parameter is used to calculate the user data area capacity in the SD memory card (not include the protected area). The user data area capacity is calculated from C_SIZE as follows: memory capacity = (C_SIZE+1) * 512K byte As the maximum capacity of the Physical Layer Specification Version 2.
PERM_WRITE_PROTECT Permanently protects the whole card content against overwriting or erasing (all write and erase commands for this card are permanently disabled). The default value is ‘0’, i.e. not permanently write protected. TMP_WRITE_PROTECT Temporarily protects the whole card content from being overwritten or erased (all write and erase commands for this card are temporarily disabled). This bit can be set and reset. The default value is ‘0’, i.e. not write protected.
4. RCA Register The writable 16-bit relative card address register carries the card address that is published by the card during the card identification. This address is used for the addressed host-card communication after the card identification procedure. The default value of the RCA register is 0x0000. The value0x0000 is reserved to set all cards into the Stand-by State with CMD7. 5.
6. SCR Register In addition to the CSD register there is another configuration register that named - SD CARD Configuration Register (SCR). SCR provides information on SD Memory Card's special features that were configured into the given card. The size of SCR register is 64 bit. This register shall be set in the factory by the SD Memory Card manufacturer. The following table describes the SCR register content.
SD_SPEC Describes the SD Memory Card Physical Layer Specification version supported by this card. SD_SPEC 0 1 Physical Layer Specification Version Number Version 1.0-1.01 Version 1.10 Version 2.00 or Version 3.00 (Refer to SD_SPEC3) reserved 2 3-15 Physical Layer Specification Version SD_SPEC3 SD_SPEC SD_SPEC3 Physical Layer Specification Version Number 2 0 Version 2.00 2 1 Version 3.00 The card manufacturer determines SD_SPEC value by conditions indicated below.

SD_BUS_WIDTHS Describes all the DAT bus widths that are supported by this card. SD_BUS_WIDTHS Supported Bus Widths Bit 0 1 bit (DAT0) Bit 1 reserved Bit 2 4 bit (DAT0-3) Bit 3 reserved SD Memory Card Supported Bus Widths Since SD Memory Card shall support at least the two bus modes 1bit or 4bit width then any SD Card shall set at least bits 0 and 2 (SD_BUS_WIDTH="0101").
