An EDMA transfer is always defined in terms of three dimensions. Figure 16-18 shows the three dimensions used by EDMA controller transfers. These three dimensions are defined as:
The reference point for the index depends on the synchronization type. The amount of data transferred upon receipt of a trigger/synchronization event is controlled by the synchronization types (EDMA_TPCC_OPT_n[2] SYNCDIM bit). For these three dimensions, only two synchronization types are supported: A-synchronized transfers and AB-synchronized transfers.
