The following table lists the correspondence between the CSD entries and the command classes. A ‘+’ entry indicates that
the CSD field affects the commands of the related command class.
5.5.4 Extended CSD Register
The Extended CSD register defines the card properties and selected modes. It is 512 bytes long.
The most significant 320 bytes are the Properties segment, which defines the card capabilities and cannot be modified by
the host. The lower 192 bytes are the Modes segment, which defines the configuration the card is working in. These
modes can be changed by the host by means of the SWITCH command
