8.4.7
The DMAC can be activated by an internal interrupt, external request, or auto-request. The
available activation sources differ depending on the transfer mode and channel as indicated in
table 8.11.

Auto-request
Activation by Internal Interrupts: When an interrupt request is selected as a DMAC activation
source and the DTE bit is set to 1, that interrupt request is not sent to the CPU. It is not possible
for an interrupt request to activate the DMAC and simultaneously generate a CPU interrupt.
When the DMAC is activated by an interrupt request, the interrupt request flag is cleared
automatically. If the same interrupt is selected to activate two or more channels, the interrupt
request flag is cleared when the highest-priority channel is activated, but the transfer request is
held pending on the other channels in the DMAC, which are activated in their priority order.
