In normal transfer mode, transfer of one data access size unit is processed in response to one
transfer request. The total transfer size of up to 4 Gbytes can be set by EDTCR. EDBSR is invalid
in normal transfer mode.
The ETEND signal is output only for the last EXDMA transfer. The EDRAK signal is output each
time a transfer request is accepted and transfer processing is started.
Figure 11.7 shows examples of transfer timing in normal transfer mode and figure 11.8 shows the
normal transfer mode operation in dual address mode.
