The icnt0 parameter in a TR is never allowed to be 0 as this would cause zero byte count transactions to be issued on the bus and it unproductive towards completion of any useful work. The Rx UTC engine in the UDMA will trap any TR for which the icnt0 is zero and will immediately return a transfer response with the TR icnt0 error conditions set without performing any data transfer and without outputting any events (including end of TR event).
