Data error messages
If a read operation fails, a data error message is returned to the host instead of the
requested data. Data Error Messages are one byte long.

meaning of the bits.
Clearing Status Register bits
In SPI mode, Error and Status bits are reported to the host in three different formats:
●
●
●
The same bits may exist in multiple response types (for example Address out of range).
All Error bits defined in MultiMediaCard mode, with the exception of Underrun and Overrun,
have the same meaning and usage in SPI mode. There are some differences in the Status
bits due to the different protocol (for example Current state is not defined in SPI mode).
The detection mode and clear condition of Error and Status bits are identical to
MultiMediaCard mode, except for Error bits which are cleared when read by the host,
regardless of the response format.
Not all status bits are meaningful all the time. The relevant bits depend on the classes
supported by the device. If all the classes that affect a status/error, are not supported by the
device, the bit is not relevant and can be ignored by the host.
