Section 8 DMA Controller
Transfers can be requested (activated) by an external request or auto-request. An auto-requested
transfer is activated by the register settings alone. The designated number of transfers are executed
automatically. Either cycle-steal or burst mode can be selected. In cycle-steal mode the DMAC
releases the bus temporarily after each transfer. In burst mode the DMAC keeps the bus until the
transfers are completed, unless there is a bus request from a higher-priority bus master.
For the detailed settings see section 8.3.4, Data Transfer Control Registers (DTCR).
