Specific MMC norms: CMD1, CMD2 & CMD3 are processed in the open-drain mode. The CMD line is driven with push-pull drivers. Specific SD norms: There is no open drain mode in SD memory card. Responses types: R1, R3, R4 & R5 use a 48 bits response protected by a 7bit CRC checksum
R1b assert the BUSY signal and respond with R1. If the busy signal is asserted, it is done two clock cycles (Nsr time) after the end bit of the command. The DAT0 line is driven low. DAT1-DAT7 lines are driven by the card though their values are not relevant. R2 use a 136 bits response protected by a 7bit CRC checksum The content is CID or CSD Specific MMC norms:
