[. . . ] The MID number is controlled, defined, and allocated to a SD Memory Card manufacturer by the SD-3C, LLC. This procedure is established to ensure uniqueness of the CID register. · OID A 2-character ASCII string that identifies the card OEM and/or the card contents (when used as a distribution media either on ROM or FLASH cards). The OID number is controlled, defined, and allocated to a SD Memory Card manufacturer by the SD-3C, LLC. This procedure is established to ensure uniqueness of the CID register. Note: SD-3C, LLC licenses companies that wish to manufacture and/or sell SD Memory Cards, including but not limited to flash memory, ROM, OTP, RAM, and SDIO Combo Cards. SD-3C, LLC is a limited liability company established by Matsushita Electric Industrial Co. Ltd. , SanDisk Corporation and Toshiba Corporation. · PNM The product name is a string, 5 ASCII characters long. · PRV Transcend Information Inc. 12 SDHC Card seriies SDHC Card ser es 4~32GB High Capacity Secure Digital Card 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. · 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). 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 Register Table 5-16 shows Definition of the CSD for the High 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. The card command class register CCC defines which command classes are supported by this card. A value of `1' in a CCC bit means that the corresponding command class is supported. · READ_BL_LEN This field is fixed to 9h, which indicates READ_BL_LEN=512 Byte. · READ_BL_PARTIAL This field is fixed to 0, which indicates partial block read is inhibited and only unit of block access is allowed. · WRITE_BLK_MISALIGN This field is fixed to 0, which indicates write access crossing physical block boundaries is always disabled in High Capacity SD Memory Card. · READ_BLK_MISALIGN This field is fixed to 0, which indicates read access crossing physical block boundaries is always disabled in High Capacity SD Memory Card. · DSR_IMP Defines if the configurable driver stage is integrated on the card. If set, a driver stage register (DSR)must be implemented also. Transcend Information Inc. 16 SDHC Card seriies SDHC Card ser es 4~32GB 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). 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. 00 is 32 GB, the upper 6 bits of this field shall be set to 0. · ERASE_BLK_EN This field is fixed to 1, which means the host can erase one or multiple units of 512 bytes. · SECTOR_SIZE This field is fixed to 7Fh, which indicates 64 KBytes. Version 2. 00 cards indicates memory boundary by AU size and this field should not be used. · WP_GRP_SIZE This field is fixed to 00h. [. . . ] 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. This register shall be set in the factory by the SD Memory Card manufacturer. [. . . ]
