SDRAM controller) that function as bus masters apart from the CPU. These controllers
operate independently and assert a bus request as required. The controller that
receives a bus acknowledgement acts as the bus master. No priorities are assigned to
these three controllers, and bus requests are processed in the order in which they are
asserted. Once one of the controllers owns the bus, bus requests from other controllers
are put on hold until the bus is released again. While one of the controllers is occupying
the bus, CPU processing including non-maskable interrupt requests is also put on hold.

the addresses to be accessed by the DMAC should be specified using logical addresses.
The DMAC accesses the specified source and destination addresses according to the
