4.2 DMA Controller Registers
The DMA Controller is comprised of several identical DMA Channels depending upon the
required configuration. Each individual DMA channel has an identical register map (although
LITE channels have less functionality and hence less registers).
DMA Channel 0 is located at the address of 0x7E007000, Channel 1 at 0x7E007100, Channel
2 at 0x7E007200 and so on. Thus adjacent DMA Channels are offset by 0x100.
DMA Channel 15 however, is physically removed from the other DMA Channels and so has
a different address base of 0x7EE05000.
