  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
