For more details about response formats, please refer to the SD memory card specification.
R1b is identical to R1 with an optional busy signal transmitted on the data line. The
card may become busy after receiving these commands, depending on the state it was
in prior to receiving the command. The host has to check for busy in the response
R2 (CID, CSD register): the code length is 136 bits. The contents of the CID register
are sent as a response to the CMD2 and CMD10 commands. The contents of the CSD
register are sent as a response to CMD9. Only the bits [127...1] of the CID and CSD
registers are transferred, the reserved bit [0] of these registers is replaced by the end
bit of the response (see
R3 (OCR register): the code length is 48 bits. The contents of the OCR register are
sent as a response to ACMD41 (see
R6 (published RCA response): the code length is 48 bits. Bits 45 to 40 indicate the
index of the command to respond to. In this case it is '000011' (together with bit 5 in the
status bits it means = CMD3) as shown in
the argument field are used for the published RCA number
R7(card interface condition): the code length is 48 bits. The card support voltage
information is sent by the response of CMD8. Bits 19 to 16 indicate the voltage range
that the card supports. The card that accepted the supplied voltage returns R7
response. In the response, the card echoes back both the voltage range and check
pattern set in the argument.
