8.4.2.3 DMA cycle types
2010-12-21 - d0034_Rev0.90
After a DMA transfer completes, the controller polls all the DMA channels that are available. Figure 8.2 (p.
47) shows the process it uses to determine which DMA transfer to perform next.
Figure 8.2. Polling flowchart
The cycle_ctrl bits control how the controller performs a DMA cycle. You can set the cycle_ctrl bits as
Table 8.3 (p. 48) lists.
