Clearing Status Bits
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
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 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:
