SPI mode commands
All the SPI commands are 6 bytes long. The command always starts with the left bit of the
string, which corresponds to the command code. See
format.
The commands in SPI mode are divided into several classes as in MultiMediaCard mode.
However, the supported and available classes are different for each mode. See
details.
Table 66
argument is required in the command, the value of the field should be set to ‘0’. Reserved
commands are reserved in both MultiMediaCard and SPI modes. The contents of the
command index field is binary: for example it is ‘000000’ for CMD0 and ‘100111’ for CMD39.
