ECSD Register
ECSD Register
The 512-byte extended card-specific data (ECSD) register defines device properties and
selected modes. The most significant 320 bytes are the properties segment. This seg-
ment defines device capabilities and cannot be modified by the host. The lower 192
bytes are the modes segment. The modes segment defines the configuration in which
the device is working. The host can change the properties of modes segments using the
SWITCH command.
