Chapter 31: LPC176x/5x General Purpose DMA (GPDMA)
• Source start address 0x2003 1200.
• Destination address set to the destination peripheral address.
• Transfer width, word (32-bit).
• Transfer size, 3072 bytes (0xC00).
• Source and destination burst sizes, 16 transfers.
• Next LLI address, 0x0.
Because the next LLI address is set to zero, this is the last descriptor, and the DMA
channel is disabled after transferring the last item of data. The channel is probably set to
generate an interrupt at this point to indicate to the ARM processor that the channel can
be reprogrammed.
