General Description The Secure Digital (SD) card version 3.0 is fully compliant to the specification released by SD Card Association. The Command List supports [Part 1 Physical Layer Specification Ver3.0 Final] definitions. Card Capacity of Non-secure Area, Secure Area Supports [Part 3 Security Specification Ver3.0 Final] Specifications. The SD 3.0 card is based on 9-pin interface, designed to operate at a maximum operating frequency of 50MHz. It can alternate communication protocol between the SD mode and SPI mode. It performs data error detection and correction with very low power consumption. Its capacity could be more than 1GB and up to 16GB in the future with FAT32 which is called SDHC (SD High Capacity). Secure Digital 3.0 card is one of the most popular cards today based on its high performance, good reliability and wide compatibility. Page1 DCC.

They start to operate as DAT lines after SET_BUS_WIDTH command. The Host shall keep its own DAT1-DAT3 lines in input mode, as well, while they are not used. It is defined so, in order to keep compatibility to MultiMedia Cards. Page4 DCC.

This resistor serves two functions Card detection and Mode Selection. For Mode Selection, the host can drive the line high or let it be pulled high to select SD mode. If the host wants to select SPI mode it should drive the line low. For Card detection, the host detects that the line is pulled high. This pull-up should be disconnected by the user, during regular data transfer, with SET_CLR_CARD_DETECT(ACMD42) command.
