The 4 least significant bits (LSB) are the same error bits as in the response format R2.
4.10.15 Clearing Status Bits
SPI Mode Status Bits
MultiMediaCard
As described in the previous paragraphs, in SPI mode, status bits are reported to the host in three
different formats : response R1, response R2 and data error token (the same bits may exist in multiple
response types – e.g. Card ECC failed)
As in the MultiMediaCard mode, error bits are cleared when read by the host, regardless of the
response format. State indicators are either cleared by reading or in accordance with the card state. All
Error/Status bits defined in MultiMediaCard mode, with the exception of the underrun and overrun,
have the same meaning and usage in SPI mode. The following table summarizes the set and clear
conditions for the various status bits :

R: Detected and set for the actual command response.
X: Detected and set during command execution. The host must poll the card by sending status
A : According to the card state.
C: Clear by read.
E: Error bit.
S: Status bit.
