Section 7 DMA Controller (DMAC)
7.5.16
If the DTE bit for the channel currently operating is cleared to 0, the DMAC stops on completion
of the 1-byte or 1-word transfer in progress. DMAC operation resumes when the DTE bit is set to
1 again.
In full address mode, the same applies to the DTME bit.
Figure 7.37 shows the procedure for forcibly terminating DMAC operation by software.

If you want to prevent interrupt generation after
forced termination of DMAC operation, clear the
DTIE bit to 0 at the same time.
