Section 7 DMA Controller (DMAC)
7.5.16
Figure 7.37 shows the procedure for releasing and initializing a channel designated for full address
mode. After full address mode has been cleared, the channel can be set to another transfer mode
using the appropriate setting procedure.

[3] Clear the FAE bit in DMABCRH to 0.
DMABCRL to 0, or wait until the transfer ends
and the DTE bit is cleared to 0, then clear the
DTME bit to 0. Also clear the corresponding
DTIE bit to 0 at the same time.
To prevent interrupt generation after forced
termination of DMAC operation, clear the DTIE bit
to 0 at the same time.
