does anybody know what is the meaning of the (bits)11:0 TRANSFERSIZE field in the DMA Channel Control registers?
Should it be number of transfers with a width DWIDTH => number of transfered bytes = (2^DWIDTH) * TRANSFERSIZE?

It is not clear for me from the user manual v2.1. From PDL's DMA example it seems to be number of transfers, not bytes. I did not read ARM PL081 and I am trying to avoid this...

Thank you for any hints
