SPB_MULTI_SPI_READ_TRANSFER structure (spb.h)

  • Article

The SPB_MULTI_SPI_READ_TRANSFER structure describes a read operation to be executed in a Multi-SPI (e.g. Dual SPI or Quad SPI) mode. It is comprised of a SPB_MULTI_SPI_TRANSFER structure containing the parameters and first write phase of the transfer, and an additional transfer phase structure for the read phase of the transfer.

Syntax

typedef struct SPB_MULTI_SPI_READ_TRANSFER {
  SPB_MULTI_SPI_TRANSFER  SpiTransfer;
  SPB_TRANSFER_LIST_ENTRY ExtraTransfer;
} SPB_MULTI_SPI_READ_TRANSFER, *PSPB_MULTI_SPI_READ_TRANSFER;

Members

SpiTransfer

A SPB_MULTI_SPI_TRANSFER structure containing the parameters of the transfer, and the write phase buffer.

ExtraTransfer

An extra SPB_TRANSFER_LIST_ENTRY structure containing the read phase buffer of the transfer operation.

Remarks

After initialization using SPB_MULTI_SPI_READ_TRANSFER_INIT, a peripheral driver may access the member SpiTransfer.TransferPhases[] to configure the transfer buffers.
