Section 11 EXDMA Controller (EXDMAC)
When a word or longword is specified as a data access size but the source or destination address is
not at the word or longword boundary, use the appropriate data access size for efficient data
transfer.
In an example shown in figure 11.56, a longword-size transfer is performed with 4-longword
specified as a cluster size in the cluster transfer dual address mode from the lower two bits of B'11
to B'10.
