User manual
The GPDMA is configured using the following registers:
The DMA controller allows peripheral-to memory, memory-to-peripheral, and
memory-to-memory transactions. Each DMA stream provides unidirectional serial DMA
transfers for a single source and destination. For example, a bi-directional port requires
one stream for transmit and one for receives. The source and destination areas can each
be either a memory region or a peripheral.
1. Power: In the PCONP register
2. Clock: see
3. Interrupts: Interrupts are enabled in the NVIC using the appropriate Interrupt Set
4. Programming: see

Chapter 31: LPC17xx General Purpose DMA (GPDMA)
Rev. 2 — 19 August 2010
Remark: On reset, the GPDMA is disabled (PCGPDMA = 0).
Enable register.
Eight DMA channels. Each channel can support an unidirectional transfer.
16 DMA request lines.
Memory-to-memory, memory-to-peripheral, and peripheral-to-memory transfers are
supported.
GPDMA supports the SSP, I2S, UART, A/D Converter, and D/A Converter peripherals.
DMA can also be triggered by a timer match condition. Memory-to-memory transfers
and transfers to or from GPIO are also supported.
Scatter or gather DMA is supported through the use of linked lists. This means that
the source and destination areas do not have to occupy contiguous areas of memory.
Hardware DMA channel priority.
AHB slave DMA programming interface. The DMA Controller is programmed by
writing to the DMA control registers over the AHB slave interface.
One AHB bus master for transferring data. The interface transfers data when a DMA
request goes active.
32-bit AHB master bus width.
Incrementing or non-incrementing addressing for source and destination.
Programmable DMA burst size. The DMA burst size can be programmed to more
efficiently transfer data.
Internal four-word FIFO per channel.
Supports 8-bit, 16-bit, and 32-bit wide transactions.
