Type
Programmed by the
manufacturer.
Read only for user
Programmed by the
manufacturer.
Read only for user
Programmed during
initialization, not readable
Programmed by the
manufacturer. Partially
programmable by the user.
Description
Supported voltage range, card power up status bit
Card identification number, card individual number for
identification.
Relative card address, local system address of a card,
dynamically assigned by the host during initialization.
Card specific data, information about the card operation
conditions.
The CID and RCA are used for identifying and addressing the MultiMediaCard. The CSD contains the
card specific data record. This record is a set of information fields to define the operation conditions of the
MultiMediaCard.
For the user, the CID is read only register. The CSD contains read only area and some of one time or
multiple programmable area by the customer or provider. They are read out by special commands (refer to
Chapter “Commands”). The RCA registers are write only registers. Unlike CID and CSD, RCA looses its
contents after powering down the card. Its value is reassigned in each initialization cycle. The
MultiMediaCard registers usage in SPI mode is summarized in Table “MultiMediaCard Registers in SPI
Mode”:
