8.5 Interrupts
The DMAC generates only DMA-end interrupts. Table 8-13 lists the interrupts and their priority.
Table 8-13 DMAC Interrupts
Group
0
1
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 > channel 2 > channel 3, and
channel A > channel B. The interrupt priority order between groups can be modified in interrupt
priority register B (IPRB).
Figure 8-26 shows the DMA-end interrupt logic. An interrupt is requested whenever DTE = 0 and
DTIE = 1.
