User Software Control

If the user clears the DGO bit, the message will be stopped and the DMA will remain in the current configuration.

For example, if the user clears the DGO bit after source data has been read, but before it is written to the destination, then the data in the DMAnBUF register will not reach its destination.

This is also referred to as a soft-stop as the operation can resume, if desired, by setting the DGO bit again.
