#define	SDMMC_CLOCK_INIT 400000

Macros for command definition
Commands types: broadcast commands (bc), no response broadcast commands with response (bcr) (Note: No open drain on SD card) addressed (point-to-point) commands (ac), no data transfer on DAT lines addressed (point-to-point) data transfer commands (adtc), data transfer on DAT lines 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 R1 receiv data not specified R3 receiv OCR R4, R5 RCA management (MMC only) R6, R7 RCA management (SD only) 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: R4 (Fast I/O) return RCA R5 (interrupt request) return RCA null Specific SD norms: R6 (Published RCA) return RCA R7 (Card interface condition) return RCA null
