|
|
* 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
