12.5.2 DMA Configuration Parameters
Setup and control of the DMA operation is
performed by the user software. This section
describes the parameters which must be
configured before a DMA channel can be
used. Section 12.5.3 on Page 102 describes
how the parameters are set up in software and
passed to the DMA controller.
