Interrupt Sources
The sources of interrupts generated by the DMAC are transfer end and transfer break. Table 7.12
shows the interrupt sources and their priority order.

[1] Clear both the DTE bit and DTME bit in
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.
