5.7.2.6 Error Status Indication
On detecting Illegal Command Error or Command CRC Error, the card indicates the error to the next R1
response. Backend errors of Extension Functions (ex. network error of I/O function, etc.) shall not be
indicated in R1 (backend errors are reserved for memory) and shall be handled by using Error Status
register, which is defined by each function specification. Interface errors (ex. illegal argument of
CMD48/49/58/59) may be indicated to R1 or Error Status register.
