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. One status bit is set if the card power up procedure has been finished. [. . . ] 2) This bit is set to LOW if the card has not finished the power up routine. 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. It contains the card identification information used during the card identification phase. Every individual flash card shall have a unique identification number. The structure of the CID register is defined in the following paragraphs: Name Manufacturer ID OEM/Application ID Product name Product revision Product serial number reserved Manufacturing date CRC7 checksum not used, always 1 Field MID OID PNM PRV PSN -MDT CRC Width 8 16 40 8 32 4 12 7 1 CID-slice [127:120] [119:104] [103:64] [63:56] [55:24] [23:20] [19:8] [7:1] [0:0] The CID Fields · MID An 8-bit binary number that identifies the card manufacturer. 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. Transcend Information Inc. 12 TS4GSDHC80I Rev1. 1 Industrial High Capacity Secure Digital Card 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. SDHC and SDXC Cards do not support write protected groups. · WP_GRP_ENABLE This field is fixed to 0. SDHC and SDXC Cards do not support write protected groups. Transcend Information Inc. 18 TS4GSDHC80I · R2W_FACTOR Rev1. 1 Industrial High Capacity Secure Digital Card This field is fixed to 2h, which indicates 4 multiples. Write timeout can be calculated by multiplying the read access time and R2W_FACTOR. However, the host should not use this factor and should use 250 ms for write timeout · WRITE_BL_LEN This field is fixed to 9h, which indicates WRITE_BL_LEN=512 Byte. · 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). The COPY bit is a one time programmable bit except ROM card. · PERM_WRITE_PROTECT Permanently protects the whole card content against overwriting or erasing (all write and erase commands for this card are permanently disabled). 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). Host should not use this field. · CRC The CRC field carries the check sum for the CSD contents. The checksum has to be recalculated by the host for any CSD modification. The following table lists the correspondence between the CSD entries and the command classes. A `+' entry indicates that the CSD field affects the commands of the related command class. Transcend Information Inc. 19 TS4GSDHC80I 4. [. . . ] 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.
