8.5
The DMAC generates only DMA-end interrupts. Table 8.13 lists the interrupts and their priority.

DEND0A
DEND0B
DEND1A
DEND1B
Each interrupt is enabled or disabled by the DTIE bit in the corresponding data transfer control
register (DTCR). Separate interrupt signals are sent to the interrupt controller.
The interrupt priority order among channels is channel 0 > channel 1 and channel A > channel B.
Figure 8.25 shows the DMA-end interrupt logic. An interrupt is requested whenever DTE = 0 and
DTIE = 1.
The DMA-end interrupt for the B channels (DENDB) is unavailable in full address mode. The
DTME bit does not affect interrupt operations.
