Figure 7.38 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.

Section 7 DMA Controller (Not Supported in the H8S/2321)
[1] Clear both the DTE bit and the DTME bit in
[2] Clear all bits in DMACRA and DMACRB to 0.
[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.
