Controller
DMA
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
simple bus arbiter, an address decoder, an abort status, a misalignment detector and an
Embedded Flash Controller. In addition, the MC contains a Memory Protection Unit (MPU) con-
sisting of 16 areas that can be protected against write and/or user accesses. Access to
peripherals can be protected in the same way.
