Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card 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.
Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card 1) This bit is valid only when the card power up status bit is set. 2) This bit is set to LOW if the card has not finished the power up routine. 3) Only UHS-I card supports this bit. A voltage range is not supported if the corresponding bit value is set to LOW. As long as the card is busy, the corresponding bit (31) is set to LOW. 2. CID Register The Card Identification (CID) register is 128 bits wide.

Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card 3. CSD Register The CSD Register shows Definition of the CSD for the High Capacity SD Memory Card and Extended Capacity SD Memory Card (CSD Version 2.0). The following sections describe the CSD fields and the relevant data types for the High Capacity SD Memory Card. CSD Version 2.0 is applied to SDHC and SDXC Cards. The field name in parenthesis is set to fixed value and indicates that the host is not necessary to refer these fields.

Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card • 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. TAAC bit position code 2:0 time unit 0=1ns, 1=10ns, 2=100ns, 3=1µs, 4=10µs, 5=100µs, 6=1ms, 7=10ms 6:3 time value 0=reserved, 1=1.0, 2=1.2, 3=1.3, 4=1.5, 5=2.0, 6=2.5, 7=3.0, 8=3.5, 9=4.0, A=4.5, B=5.0, C=5.5, D=6.0, E=7.0, F=8.
Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card 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).
Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card DSR_IMP DSR type 0 no DSR implemented 1 DSR implemented DSR Implementation Code Table • 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).
Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card • WRITE_BL_PARTIAL This field is fixed to 0, which indicates partial block read is inhibited and only unit of block access is allowed. • FILE_FORMAT_GRP This field is set to 0. Host should not use this field. • COPY Defines whether the contents is original (=0) or has been copied (=1). Setting this bit to 1 indicates that the card content is a copy. The COPY bit is a one time programmable bit except ROM card.
Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card 5. DSR Register (Optional) The 16-bit driver stage register can be optionally used to improve the bus performance for extended operating conditions (depending on parameters like bus length, transfer rate or number of cards). The CSD register carries the information about the DSR register usage. The default value of the DSR register is 0x404. 6.

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 Physical Layer Specification Version 2 3-15 • SD_SPEC3 SD_SPEC SD_SPEC3 Physical Layer Specification Version Number 2 0 Version 2.00 2 1 Version 3.
Rev. 1.0 SDHC10 Card series 4~32GB High Capacity Secure Digital Card The basic rule of setting this field: SDSC Card sets this field to 2 (Version 1.01) SDHC Card sets this field to 3 (Version 2.00). SDXC Card sets this field to 4 (Version 3.xx). Note that it is mandatory for a regular writable SD Memory Card to support Security Protocol. • SD_BUS_WIDTHS Describes all the DAT bus widths that are supported by this card.
