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 format shown in Figure 5-19.
Figure 5-19
The four least significant bits (LSB) are the same error bits as in the response format R2.
In SPI Mode, status bits are reported to the host in three different formats: response R1,
response R2, and data-error token.
when read by the host, regardless of the response format.
