The selected channel begins transfer after the currently transferring channel releases the bus. If
there is a bus request from a bus master other than the EXDMAC at this time, a cycle for the other
bus master is initiated. If there is no other bus request, the bus is released for one cycle.
Figure 8.14 shows examples of transfer timing in cases that include auto request cycle steal mode.
