18. Memory Controller (MC)
18.1
The Memory Controller (MC) manages the ASB bus and controls accesses requested by the masters, typically the
ARM7TDMI processor and the Peripheral DMA Controller. It features a bus arbiter, an address decoder, an abort status, a
misalignment detector and an Embedded Flash Controller.
