7.5.15
If the DTE bit in DMABCRL is cleared to 0 for the channel currently operating, 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 in DMABCRL.
Figure 7.36 shows the procedure for forcibly terminating DMAC operation by software.
