After reset, all threads on PSI-L are uninitialized and unpaired. The Host will pair each destination PDMA channel with (typically) a corresponding source channel in the UDMA-P. The PDMA thread is configured to point to the UDMA-P thread and the UDMA-P thread is configured to point to the PDMA thread. Once paired, the source channels in the UDMA-P will send all their data to the destination channel in the PDMA and the destination channel in the PDMA will never see any data other than data from the source channel in the UDMA-P.
