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.
