Notes:
1. This field is depended on the model. Refer to also C_SIZE_MULT
2. This field is depended on the model
3. This field is depended on the model. Refer to also C_SIZE
4. x means user programmable
5. This field is depended on the model. Refer to also ERASE_GRP_SIZE
Some of the CSD fields are one-time or multiple programmable by the customer or provider. All other
field values are fixed. The following section describes the CSD fields and their values for
MultiMediaCards :
CSD Register Structure
CSD_STRUCTURE
“10”
CSD Register Structure
CSD version No. 1.2
The CSD version of these MultiMediaCards is related to the “MultiMediaCard system specification,
Version 3.31”. The parameter CSD_STRUCTURE has permanently the value “10”.
