Section 9 DMA Controller (DMAC)
9.5.2
(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. The DACK signal is output every time a
transfer request is received and a transfer starts.
Figure 9.7 shows an example of the signal timing in normal transfer mode and figure 9.8 shows
the operation in normal transfer mode.
