The DRU PSI-L TR submission is used for TR submissions from an external UDMA-C. The DRU has a single submission thread for each channel. The channel must be configured as UDMA-C type channel before PSI-L pairing.
The PSI-L pairing, TR submission and response follow the mechanisms as described in PSI-L. For every TR a TR response is sent. If the TR fails a legal check or channel ownership or FIFO fullness check, an immediate TR response is sent back with the cause of the submission error provided in the response.
