Secure Digital Host Controller (SDHC)
28.3.2.11 SDHC Command Number (SDHC_CMD) Register
The command to the SD card is always 48 bits long. It contains 1 start bit, 1 direction bit, 6 command
number bits, 32 argument bits, 7 CRC bits, and 1 end bit. For more details on the format of the command,
refer to the SD physical layer spec. Refer to related card specification for detailed information about each
command.
The SDHC Command Number (SDHC_CMD) register automatically generates the command start bit,
direction bit, CRC7 bits, and end bit in hardware. Configure only the SDHC_CMD register and SDHC
Command Argument (SDHC_ARG) register to issue a command to the card.
