PRODUCTION DATA
请参考 PDF 数据表获取器件具体的封装图。
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 7-41. The application must ensure that only one of these DMA request sources is enabled at any time.
