Command Description
Table 5-4
Key:
Table 5-5 provides a detailed description of the SPI Mode commands. The responses are
defined in Section 4-16.
A “yes” in the SPI Mode column indicates that the command is supported in SPI Mode.
With these restrictions, the command class description in the CSD is still valid. If a
command does not require an argument, the value of this field should be set to zero.
Reserved SPI commands are also reserved in MultiMediaCard mode.
The binary code of a command is defined by the mnemonic symbol. As an example, the
content of the CMD Index field for CMD0 is (binary) “000000” and for CMD39 is (binary)
“100111”.
