Function
Transfer size. This field sets the size of the transfer. The transfer size value must be set before the
channel is enabled. Transfer size is updated as data transfers are completed.
A read from this field indicates the number of transfers completed on the destination bus. Reading
the register when the channel is active does not give useful information because by the time that the
software has processed the value read, the channel might have progressed. It is intended to be used
only when a channel is enabled and then disabled.
Source burst size. Indicates the number of transfers that make up a source burst. This value must be
set to the burst size of the source peripheral, or if the source is memory, to the memory boundary
size. The burst size is the amount of data that is transferred when the DMACBREQ signal goes
active in the source peripheral.

Destination burst size. Indicates the number of transfers that make up a destination burst transfer
request. This value must be set to the burst size of the destination peripheral or, if the destination is
memory, to the memory boundary size. The burst size is the amount of data that is transferred when
the DMACBREQ signal goes active in the destination peripheral.

Source transfer width. Transfers wider than the AHB master bus width are illegal. The source and
destination widths can be different from each other. The hardware automatically packs and unpacks
the data as required.
