95 / 159 page  TMS570LS3137 www.ti.com SPNS162. – SEPTEMBER 2011 4.16.2 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 4-32. The application must ensure that only one of these DMA request sources is enabled at any time. Table 4-32.
