  • SDIO_FLAG_DTIMEOUT: Data timeout
  • 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
  • SDIO_FLAG_DBCKEND: Data block sent/received (CRC check passed)
  • SDIO_FLAG_SDIOIT: SD I/O interrupt received
  • SDIO_FLAG_CEATAEND: CE-ATA command completion signal received for CMD61
Return values
None
