Ver 1.0 SDHC Card series 4~16GB 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 (see Chapter 4.7). 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.
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card OCR Register Definition 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. The supported voltage range is coded as shown in Table 5-1. 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.
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card • PRV The product revision is composed of two Binary Coded Decimal (BCD) digits, four bits each, representing an “n.m” revision number. The “n” is the most significant nibble and “m” is the least significant nibble. As an example, the PRV binary value field for product revision “6.2” will be: 0110 0010 • PSN The Serial Number is 32 bits of binary number.
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card The CSD Register Fields (CSD Version 2.0) The following sections describe the CSD fields and the relevant data types. If not explicitly defined otherwise, all bit strings are interpreted as binary coded numbers starting with the left bit first. • CSD_STRUCTURE Field structures of the CSD register are different depend on the Physical Specification Version and Card Capacity.
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card 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 (See 4.6.2). • NSAC This field is fixed to 00h. NSAC should not be used to calculate time-out values.
Ver 1.0 SDHC Card series 4~16GB 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).
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card • 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).
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card This field is set to 0. Host should not use this field. • COPY Defines if the contents is original (= ‘0’) or has been copied (=’1’). The COPY bit for OTP and MTPdevices, sold to end consumers, is set to ‘1’ which identifies the card contents as a copy. The COPY bit is an one time programmable bit.
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card 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.
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card is 0x404. 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.
Ver 1.0 SDHC Card series 4~16GB High Capacity Secure Digital Card Defines the data status after erase, whether it is ‘0’ or ‘1’ (the status is card vendor dependent). • SD_SECURITY Describes the security algorithm supported by the card. SD Supported Security Algorithm Note that it is mandatory for a regular writable SD Memory Card to support Security Protocol. For ROM (Read Only) and OTP (One Time Programmable) types of the SD Memory Card, the security feature is optional.
