Fig 9-20 Breakdown of block transfer where max_abrst = 2, Case 1
The channel FIFO is alternatively half filled by a burst from the source, and then emptied by a burst to the destination until the block transfer
has completed; this is illustrated in Fig 9-21.
Fig 9-21 Channel FIFO contents at times indicated in Fig 9-20
In this example block transfer, each source or destination burst transaction is made up of two bursts, each of length 2. As Fig 9-21 illustrates,
the top two channel FIFO locations are redundant for this block transfer. However, this is not the general case. The block transfer could
proceed as indicated in Fig 9-22.
