6.17.3 Default DMA Request Map
The DMA module on this microcontroller has 32 channels and up to 48 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, see Table 6-41. The application must ensure that only one of
these DMA request sources is enabled at any time.
