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. OCR register The 32-bit operation conditions register stores the VDD voltage profile of the card. [. . . ] The OCR register shall be implemented by the cards. OCR Register Definition Transcend Information Inc. 11 TS4~16GUSDHC2-P3 TS4~16GUSDHC2-P3 4~16GB microSDHC Class 2 Card + Reader P3 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. 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: · 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). 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. Transcend Information Inc. 17 TS4~16GUSDHC2-P3 TS4~16GUSDHC2-P3 · COPY 4~16GB microSDHC Class 2 Card + Reader P3 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. · 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). not write protected. · FILE_FORMAT This field is set to 0. 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 default corresponds to the initial CSD contents. The following table lists the correspondence between the CSD entries and the command classes. [. . . ] The following table describes the SCR register content. · SCR_STRUCTURE Version number of the related SCR structure in the SD Memory Card Physical Layer Specification. SCR Register Structure Version · SD_SPEC Describes the SD Memory Card Physical Layer Specification version supported by this card. SD_SPEC 0 1 2 3-15 Physical Layer Specification Version Number Version 1. 0-1. 01 Version 1. 10 Version 2. 00 reserved Physical Layer Specification Version · DATA_STAT_AFTER_ERASE Transcend Information Inc. 20 TS4~16GUSDHC2-P3 TS4~16GUSDHC2-P3 4~16GB microSDHC Class 2 Card + Reader P3 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. In the case of Standard Capacity SD Memory Card, this field shall be set to 2 (Version 1. 01). [. . . ]
