0 START Start DMA Operation
This bit should be written with a 1 to start a new
DMA operation after the other DMA registers
are initialized. This bit can also be set after a
DMA operation has been stopped with the STOP
bit to allow the operation to complete. When
restarting a stopped DMA operation, the START
bit should not be set until the DONE bit becomes
1 after setting the STOP bit. After setting the
START bit, the DONE bit becomes clear and the
DMA controller begins performing the
operation.
