Response formats
All responses are sent via the MCCMD command line SDIO_CMD. The response
transmission always starts with the left bit of the bit string corresponding to the response
code word. The code length depends on the response type.
A response always starts with a start bit (always 0), followed by the bit indicating the
direction of transmission (card = 0). A value denoted by x in the tables below indicates a
variable entry. All responses, except for the R3 response type, are protected by a CRC.
Every command code word is terminated by the end bit (always 1).
There are five types of responses. Their formats are defined as follows:
[31:0] stuff bits
[31:0] stuff bits
[31:16] RCA
[15:0] stuff bits
[31:1] stuff bits
[0]: RD/WR

purpose/application-specific commands. The
size of the data block shall be set by the
SET_BLOCK_LEN command.
