General Procedure for Configuring DMA

To configure the processors to use DMA, use the following general proce-
dure. Note this is a generic model. For specific information refer to the
individual programming model section in the peripheral specific chapter.
1. Clear all relevant registers (DMA/peripheral control, chain
pointer).
2. Determine interaction method (enable
tus polling).
3. Define the DMA channels interrupt priority (
4. Determine the DMA channel priority (fixed or rotating).
5. Determine the DMA address region for source and destination
(index, modifier, count).
6. Determine the DMA transfer type (standard, chained, circular).
7. Set the DMA enabled bit/write index address of first TCB to the
chain pointer register.
