7.4.13
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 7.22 shows the procedure
for forcibly terminating DMAC operation by software.

NMI Interrupt
[1] Clear the DTE bit in DMABCRL to 0.
If you want to prevent interrupt generation after
forced termination of DMAC operation, clear the
DTIE bit to 0 at the same time.
