6.15.2 Default DMA Request Map
The DMA module on this microcontroller has 16 channels and up to 32 hardware DMA requests. The
module contains DREQASIx registers which are used to map the DMA requests to the DMA channels. By
default, channel 0 is mapped to request 0, channel 1 to request 1, and so on.
Some DMA requests have multiple sources, as shown in
Table 6-28
. The application must ensure that
only one of these DMA request sources is enabled at any time.
