After reset, all threads on PSI-L are uninitialized and unpaired. The Host pairs each source PDMA channel with (typically) a corresponding destination 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 PDMA send all their data to the source channel in the UDMA-P, and the destination channel in the UDMA-P never sees any data other than data from the source channel in the PDMA.
