left-hand side of the figure. The LLIs describing the transfer are to be stored contiguously
from address 0x20000.
The first LLI, stored at 0x20000, defines the first block of data to be transferred, which is
the data stored between addresses 0x0A200 and 0x0AE00:
1. Write the LLIs for the complete DMA transfer to memory. Each linked list item contains
2. Choose a free DMA channel with the priority required. DMA channel 0 has the highest
3. Write the first linked list item, previously written to memory, to the relevant channel in
4. Write the channel configuration information to the channel Configuration Register and

four words:
– Source address.
– Destination address.
– Pointer to next LLI.
– Control word.
The last LLI has its linked list word pointer set to 0. The LLIs must be stored in the

packets of data as each linked list item is loaded.
Count bit in the DMACCxControl Register. If this bit is set an interrupt is generated at
the end of the relevant LLI. The interrupt request must then be serviced and the
relevant bit in the DMACIntTCClear Register must be set to clear the interrupt.
