SPI mode responses
In SPI mode like in MultiMediaCard mode, responses are transmitted most significant bit
(MSB) first.
There are different types of responses:
R1 format
This is the format of the response sent by the device to any command received except for
the SEND_STATUS and READ_OCR commands (See R2 and R3, respectively).
R1 format responses are one byte long. Their most significant bit is always ‘0’ and the other
bits are error bits. Any one of the error bits going High, (set to ‘1’) indicates an error.
Refer to
meaning of the bits.
R1b format
It consists of the R1 response plus an optional busy flag.
The busy flag does not have a fixed number of bytes. When its value is zero, the device is
busy. When its value is different from zero, the device is ready.
