Figure 7.11 illustrates operation in normal mode.
Transfer requests (activation sources) are external requests and auto-requests.
With auto-request, the DMAC is only activated by register setting, and the specified number of
transfers are performed automatically. With auto-request, cycle steal mode or burst mode can be
selected. In cycle steal mode, the bus is released to another bus master each time a transfer is
performed. In burst mode, the bus is held continuously until transfer ends.
