Section 7 DMA Controller (DMAC)
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.
Figure 7.12 shows an example of the setting procedure for normal mode.
