TS1~2GUSD-S3 TS1~2GUSD-S3 TS1~2GUSD-S3 microSD Memory Card + Reader S3 Register Information Within the card interface six registers are defined: OCR, CID, CSD, RCA, DSR and SCR. These can be accessed only by corresponding commands (see Chapter 4.7). The OCR, CID, CSD and SCR registers carry the card/content specific information, while the RCA and DSR registers are configuration registers storing actual configuration parameters. 1.

It contains the card identification information used during the card identification phase. Every individual flash card shall have a unique identification number. The structure of the CID register is defined in the following paragraphs: • MID An 8 bit binary number that identifies the card manufacturer.

Therefore, the maximal value for the clock dependent part of the data access time is 25.5k clock cycles. The total access time NAC as expressed in the Table 34 is the sum of TAAC and NSAC. It has to be computed by the host for the actual clock rate. The r
