Section 11 EXDMA Controller (EXDMAC)
The cluster size is decremented regardless of the read or write operation in the consecutive write
sequences.

In this mode, the transfer source address is specified in the source address register (EDSAR) and
data is read from the transfer source and transferred to the cluster buffer. In this mode, the TSEIE
bit in the mode control register (EDMDR) must be set to 1.
Two data access size to 32 bytes can be specified as a cluster size for the consecutive read
operation.
The cycles in a cluster-size transfer are indivisible: another bus cycle (external access by another
bus master, refresh cycle, or external bus release cycle) does not occur in a cluster-size transfer.
ETEND pin output can be enabled or disabled by means of the ETENDE bit in EDMDR. ETEND
is output for the last read cycle. When an idle cycle is inserted before the last read cycle, the
ETEND signal is also output in the idle cycle.
In this mode, the EDACKE bit in EDMDR must be set to 0 to disable the EDACK pin output.
Figure 11.57 shows the data flow in the cluster transfer read address mode (from the external
memory to the cluster buffer), and figure 11.58 shows an example of the timing in cluster transfer
read address mode.
