Status
The response format R1 contains a 32-bit field with the name card status. This field is intended to transmit
status information which is stored in a local status register of each card to the host. The following table
defines the status register structure. The Type and Clear-Condition fields in the table are coded as follows:
• Type:
• E: Error bit.
• S: Status bit.
• 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
command in order to read these bits.
• Clear Condition:
• A: According to the card state.
• B: Always related to the previous command. Reception of a valid command will clear it (with a
delay of one command).
• C: Clear by read.
