Note:
Bit 127 down to bit 1 of CID and CSD are transferred, the reserved bit [0] is replaced by the
end bit.
CID register is sent as a response to commands CMD2 and CMD10.
CSD register is sent as a response to the CMD9.
Format R3
(OCR): response length 48 bits.
The OCR is sent as a response to the CMD1 to signalize the supported voltage range. The R0002
supports the full range from 2.0 to 3.6 V. Respectively the value of all bits of the OCR field of the
R0002 are always set to high (0xFFFFFFFF). The reserved bits are also high (0x3F and 0x7F). So
the R3 frame of the R0002 contains always the value 0x3FFFFFFFFFFF.
