11 / 66 page MultiMediaCard TM 11 The host can read the CSD register and alter the host controlled data bytes using the SEND_CSD and PROGRAM_CSD commands. 2.7 SPI Mode The SPI mode is a secondary (optional) communication protocol offered for MultiMediaCard. This mode is a subset of the MultiMediaCard protocol, designed to communicate with an SPI channel, commonly found in Motorola’s (and lately a few other vendors’) microcontrollers. 2.7.1 Negotiating Operation Conditions The operating condition negotiation function of the MultiMediaCard bus is not supported in SPI mode. The host must work within the valid voltage range (2.7 to 3.6 volts) of the card. 2.7.2 Card Acquisition and Identification The card acquisition and identification function of the MultiMediaCard bus is not supported in SPI mode. The host must know the number of cards currently connected on the bus. Specific card selection is done via the CS signal. 2.7.3 Card Status In SPI mode only 16 bits (containing the errors relevant to SPI mode) can be read out of the MultiMediaCard status register. 2.7.4 Memory Array Partitioning Memory partitioning in SPI mode is equivalent to MultiMediaCard mode. All read and write commands are byte addressable. 2.7.5 Read and Write Operations In SPI mode, only single block read/write mode is supported. 2.7.6 Data Transfer Rate In SPI mode only block mode is supported. The typical access time (latency) for each data block, in read operation, is 1.5mS. The write typical access time (latency) for each data block, in read operation, is 1.5mS. The write block operation is done in handshake mode. The card will keep DataOut line low as long as the write operation is in progress and there are no write buffers available. 2.7.7 Data Protection in the MultiMediaCard Same as for the MultiMediaCard mode. 2.7.8 Erase Same as in MultiMediaCard mode |
