User manual
The micro DMA controller is available on all LPC122x parts.
The micro DMA controller is a very low-gate-count DMA compatible with the AMBA
AHB-Lite protocol for DMA transfers. The micro DMA registers are programmed through
the APB interface.
The micro DMA controller contains an APB register interface, the AHB-Lite master
interface to the AHB multi-layer matrix, and the DMA control block (see

Chapter 21: LPC122x General purpose micro DMA controller
Rev. 1.1 — 10 March 2011
Single AHB-Lite master for transferring data using a 32-bit address bus and 32-bit
data bus.
21 DMA channels.
Dedicated handshake signals and programmable priority level for each channel.
Each priority level arbitrates using a fixed priority that is determined by the DMA
channel number.
Supports memory-to-memory, memory-to-peripheral, and peripheral-to-memory
transfers.
Supports multiple DMA cycle types and multiple DMA transfer widths.
Each DMA channel can access a primary and an alternate channel control data
structure.
The channel control data is stored in system memory in little-endian format.
Performs all DMA transfers using single AHB-Lite transfers. Burst transfers are not
supported.
The destination data width is equal to the source data width.
The number of transfers in a single DMA cycle can be programmed from 1 to 1024.
The transfer address increment can be greater than the data width.
Single output to indicate when an error condition occurs on the AHB.
