//! A helper macro for building scatter-gather task table entries.
//!
//! \param ulTransferCount is the count of items to transfer for this task.
//! \param ulItemSize is the bit size of the items to transfer for this task.
//! \param ulSrcIncrement is the bit size increment for source data.
//! \param pvSrcAddr is the starting address of the data to transfer.
//! \param ulDstIncrement is the bit size increment for destination data.
//! \param pvDstAddr is the starting address of the destination data.
//! \param ulArbSize is the arbitration size to use for the transfer task.
//! \param ulMode 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 ulTransferCount parameter is the number of items that will be
//! transferred by this task.  It must be in the range 1-1024.
//!
//! The \e ulItemSize 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 ulSrcIncrement 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 ulDstIncrement 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 ulArbSize 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 ulMode 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.
//!
//! This macro is intended to be used to initialize individual entries of
//! a structure of tDMAControlTable type, like this:
//!
//! \verbatim
//!     tDMAControlTable MyTaskList[] =
//!     {
//!         uDMATaskStructEntry(Task1Count, UDMA_SIZE_8,
//!                             UDMA_SRC_INC_8, MySourceBuf,
//!                             UDMA_DST_INC_8, MyDestBuf,
//!                             UDMA_ARB_8, UDMA_MODE_MEM_SCATTER_GATHER),
//!         uDMATaskStructEntry(Task2Count, ... ),
//!     }
//! \endverbatim
//!
//! \return Nothing; this is not a function.
