+<p>The DMAC has different DMA channels that can be configured for
+different DMA transfers. For some peripherals, such as the Camera
+and the Display controller, there can be dedicated DMA channels that
+cannot be configured for DMA transfers by other peripherals. However,
+drivers generally initialize and open a multi-purpose DMA channel
+and use that channel to perform the DMA transfers.</p>
+<p>Initialization and opening of DMA channels is done using the interface <xref href="GUID-83882548-FAC5-3EFF-92ED-14D1D9A85D37.dita"><apiname>TDmaChannel</apiname></xref>. </p>
+<note>This class is designed only for single-thread client access.
+When used by multi-threaded clients, synchronization mechanisms should
+be provided by the driver. </note>
+<p>DMA channels must be opened before use and closed after completion
+of DMA operations. </p>
