11.4.2
Table 11.5 shows cluster transfer modes. Cluster transfer mode can be set independently for each
channel. The cluster buffer is common to all channels.
Table 11.5 Cluster Transfer Mode
In cluster transfer mode, the specified cluster size is transferred in response to a single transfer
request. The cluster size can be from one access size (byte, word, or longword) to 32 bytes. Within
a cluster, a cluster-size transfer is performed in burst transfer mode. With a cluster-size access in
cluster transfer mode (dual address mode), block transfer mode (dual address mode) is used.
With auto-requests, cycle steal mode is set.
