10.2.2 Internal M2P/P2M Channel Register Map
The DMA Memory Map above includes the base address mapping for the channel registers
for each of the 10 M2P/P2M channels that are shown in the following table, the Internal
M2P/P2M Channel Register Map. This mapping is common for each channel thus offset
addresses from the bases in
