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.
