• Park on master core priority (PARK = 01)—The core retains bus mastership as long
• Park on master DMA priority (PARK = 10)—The DMA module retains bus
Note that the internal DMA has higher priority than the core if the internal DMA has
its bandwidth BWC bits set to 000 (maximum bandwidth).
as it needs it. After it negates its internal bus request, the core does not have to
rearbitrate for the bus unless the DMA module has requested the bus when it is idle.
The DMA module can be granted bus mastership only when the core is not asserting
its bus request. See Figure 6-11.
