17.10.2 SD/MMC Command Register 0 (HW_SSP_CMD0)
SD/MMC Command Index and control register
HW_SSP_CMD0: 0x010
HW_SSP_CMD0_SET: 0x014
HW_SSP_CMD0_CLR: 0x018
HW_SSP_CMD0_TOG: 0x01C
This is the command code for the SD/MMC devices. See device specification for details.
For eMMC Alternate boot operation, Command and RX data phases must be executed
together (HW_SSP_CTRL0_ENABLE=1 and HW_SSP_CTRL0_DATA_XFER=1) so that
SSP does not miss the boot ack or boot data phases.

Get Long Response - SD/MMC - 0: The card response will be short. 1: The card will provide a 136-bit
response. Only valid if GET_RESP is set. A long response cannot be checked using CHECK_RESP.
Check Response - SD/MMC. If this bit is set, the SSP will XOR the result with the REFERENCE field and
then mask the incoming status word with the MASK field in the COMPARE register. If there is a mismatch,
then the SSP will set the RESP_ERR status bit, and, if enabled, the RESP_ERR_IRQ. This should not be
used with LONG_RESP.
Get Response - SD/MMC - 0: Do not wait for a response from the card. 1: This command should receive a
response from the card.
Command Transmit Enable - SD/MMC - 0: Commands are not enabled. 1: Data in Command registers will
be sent. This is normally enabled in SD/MMC.
