This is a variation of early completion. Dummy or null completion is associated with a dummy set Section 16.2.4.3.4 or null set Section 16.2.4.3.3. In both cases, the EDMA channel controller does not submit the associated transfer request to the EDMA transfer controller(s). However, if the set (dummy/null) has the OPT field programmed to return completion code (intermediate/final interrupt/chaining completion), then it sets the appropriate bits in the interrupt pending registers EDMA_TPCC_IPR and EDMA_TPCC_IPRH or chained event register EDMA_TPCC_CER and EDMA_TPCC_CERH. The internal early completion path is used by the channel controller to return the completion codes internally (that is, EDMA_TPCC generates the completion code).
