A dummy PaRAM set is defined as a PaRAM set where at least one of the count fields (EDMA_TPCC_ABCNT_n[15:0] ACNT, EDMA_TPCC_ABCNT_n[31:16] BCNT, or EDMA_TPCC_CCNT_n[15:0] CCNT) is cleared to 0 and at least one of the count fields is nonzero.
If a PaRAM set associated with a channel is a dummy set, then when serviced by the EDMA_TPCC, it will not set the bit corresponding to the channel (DMA/QDMA) in the event missed register (EDMA_TPCC_EMR, EDMA_TPCC_EMRH, or EDMA_TPCC_QEMR) and the secondary event register (EDMA_TPCC_SER, EDMA_TPCC_SERH, or EDMA_TPCC_QSER) bit gets cleared similar to a normal transfer. Future events on that channel are serviced. A dummy transfer is a legal transfer of 0 bytes.
