In basic mode, the μDMA controller performs transfers as long as there are more items to transfer, and a transfer request is present. This mode is used with peripherals that assert a μDMA request signal whenever the peripheral is ready for a data transfer. Basic mode must not be used in any situation where the request is momentary, even though the entire transfer must be completed.
The μDMA controller sets the mode for that channel to stop when all of the items have been transferred using basic mode.
