DMAC Transfer Types
Hclk
Each DMAREQx assertion leads to a transfer. Its size (given by CTLxL.SRC_MSIZE and
CTLxL.DEST_MSIZE) is decremented from CTLxH.BLOCK_TS.
The external nDMAREQx signal must be de-asserted after the last transfer and re-asserted
again before a new transaction starts. The DMA ends the current transfer.
For a source FIFO, an active edge is triggered on nDMAREQx when the source FIFO exceeds a
watermark level. For a destination FIFO, an active edge is triggered on nDMAREQx when the
destination FIFO drops below the watermark level.
The source transaction length, CTLxL.SRC_MSIZE, and destination transaction length,
CTLxL.DEST_MSIZE, must be set according to watermark levels on the source/destination
peripherals.
A DMA transfer may consist of single or multi-block transfers. On successive blocks of a multi-
block transfer, the DMAC_SARx/DMAC_DARx register in the DMAC is reprogrammed using
either of the following methods:
On successive blocks of a multi-block transfer, the DMAC_CTLx register in the DMAC is re-pro-
grammed using either of the following methods:
When block chaining, using linked lists is the multi-block method of choice, and on successive
blocks, the DMAC_LLPx register in the DMAC is re-programmed using the following method:
A block descriptor (LLI) consists of following registers, DMAC_SARx, DMAC_DARx,
DMAC_LLPx, DMAC_CTLx. These registers, along with the DMAC_CFGx register, are used by
the DMAC to set up and describe the block transfer.

• Auto-reloading
• Contiguous address between blocks
