DMAC activation sources consist of internal interrupts, external requests, and auto-requests. The
activation sources that can be specified depend on the transfer mode and the channel, as shown in
table 7.12.

Legend:
X : Cannot be specified
Activation by Internal Interrupt: An interrupt request selected as a DMAC activation source
can be sent simultaneously to the CPU and DTC. For details, see section 5, Interrupt Controller.
With activation by an internal interrupt, the DMAC accepts the 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 source that is not used as a
DTC activation source (DTA = 1), the interrupt source flag is cleared automatically by the DMA
transfer. With ADI, TXI, and RXI interrupts, however, the interrupt source flag is not cleared
