Control information
The first LLI, stored at 0x2002 0000, defines the first block of data to be transferred, which
is the data stored from address 0x2002 A200 to 0x2002 ADFF:
The second LLI, stored at 0x2002 0010, describes the next block of data to be transferred:
A chain of descriptors is built up, each one pointing to the next in the series. To initialize
the DMA stream, the first LLI, 0x2002 0000, is programmed into the DMA Controller.
When the first packet of data has been transferred the next LLI is automatically loaded.
The final LLI is stored at 0x2002 0070 and contains:
