EDMA_TPCC_CIDX_n[15:0] SCIDX is a 16-bit signed value (2s complement) used for source address modification in the 3rd dimension. Valid values for EDMA_TPCC_CIDX_n[15:0] SCIDX are between –32 768 and 32 767. It provides a byte address offset from the beginning of the current array (pointed to by SRC address) to the beginning of the first source array in the next frame. It applies to both A-synchronized and AB-synchronized transfers.
When SCIDX is applied, the current array in an A-synchronized transfer is the last array in the frame (Figure 18-19), while the current array in an AB-synchronized transfer is the first array in the frame (Figure 18-20).
