55 / 66 page MultiMediaCard TM 55 command. *4 CMD25 Yes [31:0] data address R1 WRITE_MULTIPL E_BLOCK continuously writes blocks of data until a “Stop Tran” Token or the requested number of blocks received. CMD26 No CMD27 Yes None R1b PROGRAM_CSD programming of the programmable bits of the CSD. CMD28 Yes [31:0] data address R1b SET_WRITE_ PROT if the card has write protection features, this command sets the write protection bit of the addressed group. The properties of write protection are coded in the card specific data (WP_GRP_SIZE). CMD29 Yes [31:0] data address R1b CLR_WRITE_ PROT if the card has write protection features, this command clears the write protection bit of the addressed group. CMD30 Yes [31:0] write protect data address R1 SEND_WRITE_ PROT if the card has write protection features, this command asks the card to send the status of the write protection bits. *5 CMD31 reserved CMD35 Yes [31:0] data address R1 TAG_ERASE_ GROUP_START sets the address of the first erase group within a range to be selected for erase CMD36 Yes [31:0] data address R1 TAG_ERASE_ GROUP_END sets the address of the last erase group within a continuous range to be selected for erase CMD38 Yes [31:0] stuff bits R1b ERASE erases all previously selected sectors CMD39 No CMD40 No CMD41 reserved CMD42 Yes [31:0] stuff bits R1b LOCK/UNLOCK Used to set/reset the password or lock/unlock the card. The structure of the data block is described in chapter “Card lock/unlock operation”. The size of the Data Block is defined by the SET_BLOCK_LEN command. CMD43… CMD57 reserved CMD58 Yes None R3 READ_OCR Reads the OCR register of a card. CMD59 Yes [31:0] stuff bits [0:0] CRC option R1 CRC_ON_OFF Turns the CRC option on or off. A ‘1’ in the CRC option bit will turn the option on, a ‘0’ will turn it off. CMD60 No Notes : 1. The default block length is as specified in the CSD. 2. The data transferred must not cross a physical block boundary unless READ_BLK_MISALIGN is set in the CSD. 3. R1b : R1 response with an optional trailing busy signal. 4. The data transferred must not cross a physical block boundary unless WRITE_BLK_MISALIGN is set in the CSD. |
