Transcend reserves the right to make changes in specifications at any time without prior notice. 6 Transcend Information Inc. TS2GUSD-P3 Register Information 2GB microSD Card + Reader P3 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. [. . . ] 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). 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 11 Transcend Information Inc. TS2GUSD-P3 corresponding command class is supported. 2GB microSD Card + Reader P3 · READ_BL_LEN The maximum read data block length is computed as 2READ_BL_LEN. The maximum block length might therefore be in the range 512. . . 2048 bytes (see Chapter 4. 11 for details). Note that in SD Memory Card the WRITE_BL_LEN is always equal to READ_BL_LEN · READ_BL_PARTIAL (always = 1 in SD Memory Card) Partial Block Read is always allowed in SD Memory Card. It means that smaller blocks can be used as well. The minimum block size will be one byte. · WRITE_BLK_MISALIGN Defines if the data block to be written by one command can be spread over more than one physical block of the memory device. The size of the memory block is defined in WRITE_BL_LEN. WRITE_BLK_MISALIGN=0 signals that crossing physical block boundaries is invalid. WRITE_BLK_MISALIGN=1 signals that crossing physical block boundaries is allowed. · READ_BLK_MISALIGN Defines if the data block to be read by one command can be spread over more than one physical block of the memory device. The size of the memory block is defined in READ_BL_LEN. READ_BLK_MISALIGN=0 signals that crossing physical block boundaries is invalid. READ_BLK_MISALIGN=1 signals that crossing physical block boundaries is allowed. · DSR_IMP 21 Transcend Information Inc. TS2GUSD-P3 2GB microSD Card + Reader P3 Defines if the configurable driver stage is integrated on the card. If set, a driver stage register (DSR)must be implemented also. · C_SIZE This parameter is used to compute the user's data card capacity (not include the security protected area). The actual size is computed by increasing this number by one. A value of zero means 1 write block, 127 means 128 write blocks. · WP_GRP_SIZE The size of a write protected group. The contents of this register is a 7 bit binary coded value, defining the number of erase sectors (see SECTOR_SIZE). The actual size is computed by increasing this number by one. A value of zero means 1 erase sector, 127 means 128 erase sectors. · WP_GRP_ENABLE A value of `0' means no group write protection possible. · R2W_FACTOR Defines the typical block program time as a multiple of the read access time. The following table defines the field format. · WRITE_BL_LEN The maximum write data block length is computed as 2WRITE_BL_LEN. The maximum block lengthmight therefore be in the range from 512 up to 2048 bytes. [. . . ] For ROM (Read Only) and OTP (One Time Programmable) type of SD Memory Card the security feature is optional · SD_BUS_WIDTHS Describes all the DAT bus widths that are supported by this card. Since SD Memory Card shall support at least the two bus modes 1bit or 4bit width then any SD Card shall set at least bits 0 and 2 (SD_BUS_WIDTH="0101"). 02 Transcend Information Inc.
