The Tx Per Channel Buffers implement channelized FIFOs for each DMA channel. A single logical data FIFO is provided for each destination DMA channel that is used for buffering payload data that has been pushed into the PDMA from the Tx PSI-L interface. The Tx Per Channel Buffers are always written with full Tx PSI-L wide words (except for EOL/EOP data phases) but are read on byte granularity from the Tx DMA units.
