I see what you are talking about. While the external bus interface on these cold fire parts is not a pin compatible m68k cpu bus, it certainly can access memory devices and uses DMA. From the 5307 manual: 1.3.7.1 External Bus Interface The bus interface controller transfers information between the ColdFire core or DMA and memory, peripherals, or other devices on the external bus.
