Description

SC510 3BSE003832R1
The Card-Specific Data register provides information on how to access the e•MMC contents. TheCSDdefines the data format, error correction type, maximum data access time, data transfer speed, whether theDSR register can be used etc. The programmable part of the register (entries marked by Wor E, seebelow)can be changed by CMD27. The type of the entries in the table below is coded as follows:
 R:Read only
 W: One time programmable and not readable.  R/W: One time programmable and readable.  W/E: Multiple writable with value kept after power failure, H/W reset assertion and any CMD0reset andnot readable.  R/W/E: Multiple writable with value kept after power failure, H/W reset assertion and any CMD0reset
and readable.  R/W/C_P: Writable after value cleared by power failure and HW/ rest assertion (the value not clearedby CMD0 reset) and readable.  R/W/E_P:Multiple writable with value reset after power failure, H/W reset assertion and any CMD0reset and readable.  W/E/_P: Multiple writable with value reset after power failure, H/W reset assertion and any CMD0resetand not readable.
The memory configuration initially consists (before any partitioning operation) of the User DataAreaandRPMB Area Partitions and two Boot Area Partitions. The embedded device also offers the host the possibility to configure additional local memory partitionswithindependent address spaces, starting from logical address 0x00000000, for different usage models. Therefore, the memory block areas can be classified as follows: – Two Boot Area Partitions, whose size is multiple of 128 KB and where booting frome•MMCcanbeperformed. – One RPMB Partition accessed through a trusted mechanism, whose size is defined as multipleof128 KB. – Four General Purpose Area Partitions to store sensitive data or for other host usage models, whose sizes are a multiple of a Write Protect Group. Boot and RPMB Area Partitions’ sizes and attributes are defined by the memory manufacturer (read-only),while General Purpose Area Partitions’ sizes and attributes can be programmed by the host only onceinthedevice life-cycle (one-time programmable). Moreover, the host is free to configure one segment in the User Data Area to be implemented asenhancedstorage media, and to specify its starting location and size in terms of Write Protect Groups. Theattributesof this Enhanced User Data Area can be programmed only once during the device life-cycle (one-timeprogrammable).
