TS2GSD150 2GB 150x Secure Digital Card Bus Protocol SD bus Communication over the SD bus is based on command and data bit streams which are initiated by a start bit and terminated by a stop bit. • Command: a command is a token which starts an operation. A command is sent from the host either to a single card (addressed command) or to all connected cards (broadcast command). A command is transferred serially on the CMD line.

TS2GSD150 2GB 150x Secure Digital Card Figure 5: (Multiple) Block read operation The block write operation uses a simple busy signaling of the write operation duration on the DAT0 data line (see Figure 6) regardless of the number of data lines used for transferring the data. Figure 6: (Multiple) Block write operation Command tokens have the following coding scheme: Figure 7: Command token format Each command token is preceded by a start bit (‘0’) and succeeded by an end bit (‘1’).
PAGE 5
TS2GSD150 2GB 150x Secure Digital Card The CRC protection algorithm for block data is a 16 bit CCITT polynomial. Figure 8: Response token format In the CMD line the MSB bit is transmitted first the LSB bit is the last. When the wide bus option is used, the data is transferred 4 bits at a time (refer to Figure 10). Start and end bits, as well as the CRC bits, are transmitted for every one of the DAT lines. CRC bits are calculated and checked for every DAT line individually.

TS2GSD150 2GB 150x Secure Digital Card SPI bus While the SD channel is based on command and data bit streams which are initiated by a start bit and terminated by a stop bit, the SPI channel is byte oriented. Every command or data block is built of 8-bit bytes and is byte aligned to the CS signal (i.e. the length is a multiple of 8 clock cycles).
PAGE 7
TS2GSD150 2GB 150x Secure Digital Card Figure 12: Read operation - data error • Data Write Single and multiple block write operations are supported in SPI mode. Upon reception of a valid write command, the card will respond with a response token and will wait for a data block to be sent from the host. CRC suffix, block length and start address restrictions are identical to the read operation (see Figure 13).

TS2GSD150 2GB 150x Secure Digital Card Card Registers 1. OCR Register The 32-bit operation conditions register stores the VDD voltage profile of the card. In addition, this register includes a status information bit. This status bit is set if the card power up procedure has been finished. The OCR register shall be implemented by all cards. The supported voltage range is coded as shown in the following table. As long as the card is busy, the corresponding bit (31) is set to LOW.
PAGE 9
TS2GSD150 2GB 150x Secure Digital Card 4. Relative Card Address Register (RCA) The writable 16-bit relative card address register carries the card address assigned by the host during the card identification. This address is used for the addressed host-card communication after the card identification procedure. The default value of the RCA register is 0x0001. The value 0x0000 is reserved to set all cards into the Stand-by State with CMD7.
