Auto mode is similar to basic mode, except that when a transfer request is received, the transfer completes, even if the μDMA request is removed. This mode is suitable for software-triggered transfers. Generally, auto mode is not used with a peripheral.
The μDMA controller sets the mode for that channel to stop when all the items have been transferred using auto mode.
