11.6.3
As with the block transfer mode, the address register value must be set in cluster transfer mode, so
that the end of the cluster size coincides with the end of the extended repeat area range.
When an extended repeat area overflow occurs during a cluster-size transfer in the cluster transfer
mode, the extended repeat area overflow interrupt request is held pending until the end of a
cluster-size transfer, and transfer overrun will occur.
11.6.4
(1)
In cluster transfer mode, a cluster-size transfer is processed in response to one transfer request.
In an example shown in figure 11.61, the ETEND pin output is enabled, and word-size transfer is
performed with 4-byte cluster size in cluster transfer mode from the external 16-bit, 2-state access
space to the external 16-bit, 2-state access space.
