A helper macro for building scatter-gather task table entries. //! //! \param ui32TransferCount is the count of items to transfer for this task. //! \param ui32ItemSize is the bit size of the items to transfer for this task. //! \param ui32SrcIncrement is the bit size increment for source data. //! \param pvSrcAddr is the starting address of the data to transfer. //! \param ui32DstIncrement is the bit size increment for destination data. //! \param pvDstAddr is the starting address of the destination data. //! \param ui32ArbSize is the arbitration size to use for the transfer task. //! \param ui32Mode is the transfer mode for this task. //! //! This macro is intended to be used to help populate a table of uDMA tasks //! for a scatter-gather transfer. This macro will calculate the values for //! the fields of a task structure entry based on the input parameters. //! //! There are specific requirements for the values of each parameter. No //! checking is done so it is up to the caller to ensure that correct values //! are used for the parameters. //! //! The \e ui32TransferCount parameter is the number of items that will be //! transferred by this task. It must be in the range 1-1024. //! //! The \e ui32ItemSize parameter is the bit size of the transfer data. It //! must be one of \b UDMA_SIZE_8, \b UDMA_SIZE_16, or \b UDMA_SIZE_32. //! //! The \e ui32SrcIncrement parameter is the increment size for the source //! data. It must be one of \b UDMA_SRC_INC_8, \b UDMA_SRC_INC_16, //! \b UDMA_SRC_INC_32, or \b UDMA_SRC_INC_NONE. //! //! The \e pvSrcAddr parameter is a void pointer to the beginning of the source //! data. //! //! The \e ui32DstIncrement parameter is the increment size for the destination //! data. It must be one of \b UDMA_DST_INC_8, \b UDMA_DST_INC_16, //! \b UDMA_DST_INC_32, or \b UDMA_DST_INC_NONE. //! //! The \e pvDstAddr parameter is a void pointer to the beginning of the //! location where the data will be transferred. //! //! The \e ui32ArbSize parameter is the arbitration size for the transfer, and //! must be one of \b UDMA_ARB_1, \b UDMA_ARB_2, \b UDMA_ARB_4, and so on //! up to \b UDMA_ARB_1024. This is used to select the arbitration size in //! powers of 2, from 1 to 1024. //! //! The \e ui32Mode parameter is the mode to use for this transfer task. It //! must be one of \b UDMA_MODE_BASIC, \b UDMA_MODE_AUTO, //! \b UDMA_MODE_MEM_SCATTER_GATHER, or \b UDMA_MODE_PER_SCATTER_GATHER. Note //! that normally all tasks will be one of the scatter-gather modes while the //! last task is a task list will be AUTO or BASIC. //! //!
