Programmed by the

Programmable by the user
CID and RCA are used for identifying and addressing MultiMediaCard. 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 and the OCR are read only registers. 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
