The SPB_MULTI_SPI_READ_TRANSFER_INIT function initializes an SPB_MULTI_SPI_READ_TRANSFER structure.
SpiTransferA pointer to the SPB_MULTI_SPI_READ_TRANSFER structure that is to be initialized.
ModeAn SPB_MULTI_SPI_TRANSFER_MODE enumeration value, specifying the line mode of the multi-SPI transfer to be used by a bus driver to communicate with a peripheral device.
WritePhaseSingleSpiByteCountThe count of bytes at the beginning of the write phase to be transferred in single-SPI mode, before line mode switch to the mode specified in the Mode member of this struct.
WaitCycleByteCountThe number of wait cycles represented as the number of bytes, representing multi-SPI transfer cycles - e.g. 1 byte => 8 bits => 2 clock cycles in quad-SPI mode, between the write phase and read phase of the transfer. These wait cycle bytes should be present, and of an undefined value at the end of the WritePhaseBuffer.
The SPB_MULTI_SPI_READ_TRANSFER_INIT function should be used to initialize multi-SPI read transfers. It initializes a SPB_MULTI_SPI_READ_TRANSFER structure with the two transfer phases required for a read operation.
