Section 7 DMA Controller (Not Supported in the H8S/2321)
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.

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