Preliminary data sheet
6.11 DMA controller
USB-IF TestID for Hi-speed peripheral silicon and embedded host silicon: 40720018
The DMA Controller can perform DMA transfers on the AHB bus without using the CPU.

This module has its own, integrated DMA engine.
Supported transfer types:
Memory to memory copy:
– Memory can be copied from the source address to the destination address with a
Memory to peripheral:
– Data is transferred from incrementing memory to a fixed address of a peripheral.
Peripheral to memory:
– Data is transferred from a fixed address of a peripheral to incrementing memory.
Supports single data transfers for all transfer types.
Supports burst transfers for memory to memory transfers. A burst always consists of
multiples of 4 (32 bit) words.
The DMA controller has 12 channels.
Scatter-gather is used to gather data located at different areas of memory. Two
channels are needed per scatter-gather action.
Supports byte, half word and word transfers, and correctly aligns it over the AHB bus.
Compatible with ARM flow control, for single requests, last single requests, terminal
count info, and dma clearing.
Supports swapping in endianess of the transported data.
AES decryption engine is available on LPC3154 only.
specified length, while incrementing the address for both the source and
destination.
The flow is controlled by the peripheral.
The flow is controlled by the peripheral.
