1.
The 32-bit operation conditions register stores the VDD voltage profile of the card. In addition, this register includes a
status information bit. This status bit is set if the card power up procedure has been finished. The OCR register shall
be implemented by all cards. The supported voltage range is coded as shown in the following table. As long as the
card is busy, the corresponding bit (31) is set to LOW.
2. Card Identification Register (CID)
The Card IDentification (CID) register is 128 bits wide. It contains the card identification information used during the
card identification phase. Every individual flash or I/O card shall have an unique identification number. The structure
of the CID register is defined in the following
table
3. Driver Stage Register (DSR)
The 16-bit driver stage register is optionally used to improve the bus performance for extended operating
conditions.The CSD register carries the information about the DSR register usage. This register is not implemented
