• Bus Signal Levels
As the bus can be supplied with a variable supply voltage, all signal levels are related to the supply voltage.
To meet the requirements of the JEDEC specification JESD8-1A and JESD8-7, the card input and output voltages shall be
within the following specified ranges for any VDD of the allowed voltage range:
Parameter
Output HIGH voltage
Output LOW voltage
Input HIGH voltage
Input LOW voltage

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. 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. OCR register
The 32-bit operation conditions register stores the VDD voltage profile of the card. Additionally, this register includes
status information bits. One status bit is set if the card power up procedure has been finished. This register includes
another status bit indicating the card capacity status after set power up status bit. The OCR register shall be
implemented by the cards. The 32-bit operation conditions register stores the VDD voltage profile of the card. Bit 7 of
OCR is newly defined for Dual Voltage Card and set to 0 in default. If a Dual Voltage Card does not receive CMD8,
OCR bit 7 in the response indicates 0, and the Dual Voltage Card which received CMD8, sets this bit to 1.
Additionally, this register includes 2 more status information bits.
Bit 31 - Card power up status bit, this status bit is set if the card power up procedure has been finished.
Bit 30 - Card Capacity Status bit, 0 indicates that the card is SDSC. 1 indicates that the card is SDHC or SDXC. The
Card Capacity Status bit is valid after the card power up procedure is completed and the card power up
status
The OCR register shall be implemented by the cards.
