Section 10 DMA Controller (DMAC)
10.5.2
(1)
In normal transfer mode, one data access size of data is transferred at a single transfer request. Up
to 4 Gbytes can be specified as a total transfer size by DTCR. DBSR is ignored in normal transfer
mode.
The TEND signal is output only in the last DMA transfer.
Figure 10.7 shows an example of the signal timing in normal transfer mode and figure 10.8 shows
the operation in normal transfer mode.
