SD Card. SD card specifications are now maintained, controlled and assigned by the SD-3C, LLC. While a formal SD-ROM card specification does not yet exist, the SanDisk SD ROM Card has been designed to be compatible with most SD host devices today. -
Page 4: Spi Mode
Version 2.00, for details. 2.2 SPI Mode The SPI Mode is a secondary communication protocol for cards in the SanDisk SD-ROM Cards. This interface mode is an alternate to the SD protocol and is designed to communicate with an SPI channel, commonly found in Motorola and other vendors' microcontrollers. More information about SPI Mode can be found in Section 7 of the SDA Physical Layer Specification, Version 2.00. -
Page 5: Supported Commands
2.7 Card State Transitions SanDisk SD-ROM Cards operate the same as standard SD cards, where the state transition is dependent on the received command along with responses sent on the command line. The transitions are defined in Section 4.8 of the SDA Physical Layer Specification, Version 2.00 In Card Identification Mode, the host operates the card at a slower frequency as it identifies and initializes the card. -
Page 6: Operating Specifications
The SD specifications define a set of eight registers within the card interface. However, the DSR Register is optional and is not used in the SanDisk SD Card Product Family. For specific information about all registers, refer to Section 5 of the SDA Physical Layer Specification, Version 2.00. - Page 7 It is programmed during card content programming and cannot be changed by card hosts. The following table lists the default configuration of the CID register for SanDisk SD-ROM Cards. More information can be found in Section 5.2 of the SDA Physical Layer Specification, Version 2.00.
