SDIO_FLAG_TXUNDERR: Transmit FIFO underrun error
SDIO_FLAG_RXOVERR: Received FIFO overrun error
SDIO_FLAG_CMDREND: Command response received (CRC check passed)
SDIO_FLAG_CMDSENT: Command sent (no response required)
SDIO_FLAG_DATAEND: Data end (data counter, SDIDCOUNT, is zero)
SDIO_FLAG_STBITERR: Start bit not detected on all data signals in wide bus mode
