42 / 66 page MultiMediaCard TM 42 R1b is identical to R1 with an optional busy signal transmitted on the data line. The card may become busy after receiving these commands based on its state prior to the command reception Format R2 (CID, CSD register): response length 136 bits. Note: Bit 127 down to bit 1 of CID and CSD are transferred, the reserved bit [0] is replaced by the end bit Table 4-11 Format R2(CID, CSD Register) : Response Length 136 bits 0 0 bit5 … bit0 Bit127 … bit1 1 start bit card reserved CID or CSD register including internal CRC end bit Format R3 (OCR): response length 48 bits. The OCR is sent as a response to the CMD1 to signalize the supported voltage range. The MultiMediaCard supports the range from 2.7 V to 3.6 V. Respectively the value of all bits of the OCR field of the MultiMediaCard is set to 0x80FF8000. So the R3 frame of the MultiMediaCard contains the value 0x3F80FF8000FF if the card is ready and 0x3F00FF8000FF if the card is busy. Table 4-12 OCR : Response length 50Hz 0 0 bit5 … bit0 Bit31 … bit0 Bit6 … bit0 1 start bit card reserved OCR field reserved end bit 4.9.7 Status The response format R1 contains a 32-bit field with the name card status. This field is intended to transmit status information which is stored in a local status register of each card to the host. The following table defines the status register structure. The Type and Clear-Condition fields in the table are coded as follows: - Type: E: Error bit. S: Status bit. R: Detected and set for the actual command response. X: Detected and set during command execution. The host must poll the card by sending status - Clear Condition: A : According to the card state. B: Always related to the previous command. Reception of a valid command will clear it (with a delay of one command). C: Clear by read. |
