These bits enable or disable an interrupt to the
CPU or DTC when transfer ends. If the DTIE bit is
set to 1 when DTE = 0, the DMAC regards this as
indicating the end of a transfer, and issues a
transfer end interrupt request to the CPU or DTC.
A transfer end interrupt can be canceled either by
clearing the DTIE bit to 0 in the interrupt handling
routine, or by performing processing to continue
transfer by setting the transfer counter and address
register again, and then setting the DTE bit to 1.

Bit Bit Name Initial Value R/W Description
15 FAE1 0 R/W Full Address Enable 1
Specifies whether channel 1 is to be used in short
address mode or full address mode.
In full address mode, channels 1A and 1B are used
together as channel 1.
0: Short address mode
1: Full address mode
14 FAE0 0 R/W Full Address Enable 0
Specifies whether channel 0 is to be used in short
address mode or full address mode.
In full address mode, channels 0A and 0B are used
together as channel 0.
0: Short address mode
1: Full address mode
