8.4.1
An interrupt request selected as a DMAC activation source can also simultaneously generate an
interrupt request for the CPU or DTC. For details, see section 5, Interrupt Controller.
With activation by an internal interrupt request, the DMAC accepts the interrupt request
independently of the interrupt controller. Consequently, interrupt controller priority settings are
irrelevant.
If the DMAC is activated by a CPU interrupt source or an interrupt request that is not used as a
DTC activation source (DTA = 1), the interrupt request flag is cleared automatically by the DMA
transfer. With ADI, TXI, and RXI interrupts, however, the interrupt source flag is not cleared
unless the relevant register is accessed in a DMA transfer. If the same interrupt is used as an
activation source for more than one channel, the interrupt request flag is cleared when the highest-
