Data Tokens
Read and write commands have data transfers associated with them. Data is being transmitted or received
via data tokens. All data bytes are transmitted MSB first. Data tokens are 4 to 2051 bytes long and have
the following format:
First byte: Start Byte

Bytes 2-2049 (depends on the data block length): User data
Last two bytes: 16-bit CRC.
Data Error Token
If a read operation fails and the card cannot provide the required data, it will send a data error token
instead. This token is one byte long and has the following format:
Error
CC Error
Card ECC failed
out of range
Card is locked
0 0 0

7
Data Error Token
The 4 least significant bits (LSB) are the same error bits as in the response format R2.
