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.
Clearing Full Address Mode
Clear FAE bit to 0

[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.
