Table 30-27 shows the sequence for configuring EDMA for Output Parameters Transfer. This transfer is optional and depends on the OUTF bit. It is a 2- to 32-bit word VCP1REVT and VCP2REVT frames synchronized transfer.

Number of arrays in a frame | EDMA.EDMA_TPCC_ABCNT_n[15:0] BCNT | 0x1 |
Destination Address | EDMA.EDMA_TPCC_DST_n[31:0] DST | xxxx: Output Register Store Array Address |
Source 2nd Dimension Index | EDMA.EDMA_TPCC_BIDX_n[15:0] SBIDX | 0x0 |
Destination 2nd Dimension Index | EDMA.EDMA_TPCC_BIDX_n[31:16] DBIDX | 0x0 |
Source Frame Index | EDMA.EDMA_TPCC_CIDX_n[15:0] SCIDX | 0x00 |
