31.5.19 DMA Channel Linked List Item registers (DMACCxLLI - 0x5000 41x8)
0x5000 41x0)
The eight read/write DMACCxSrcAddr Registers (DMACC0SrcAddr to DMACC7SrcAddr)
contain the current source address (byte-aligned) of the data to be transferred. Each
register is programmed directly by software before the appropriate channel is enabled.
When the DMA channel is enabled this register is updated:
Reading the register when the channel is active does not provide useful information. This
is because by the time software has processed the value read, the address may have
progressed. It is intended to be read-only when the channel has stopped, in which case it
shows the source address of the last item read.
Note: The source and destination addresses must be aligned to the source and
destination widths.

0x5000 41x4)
The eight read/write DMACCxDestAddr Registers (DMACC0DestAddr to
DMACC7DestAddr) contain the current destination address (byte-aligned) of the data to
be transferred. Each register is programmed directly by software before the channel is
enabled. When the DMA channel is enabled the register is updated as the destination
address is incremented and by following the linked list when a complete packet of data
has been transferred. Reading the register when the channel is active does not provide
useful information. This is because by the time that software has processed the value
read, the address may have progressed. It is intended to be read-only when a channel
has stopped, in which case it shows the destination address of the last item read.
Table 561
The eight read/write DMACCxLLI Registers (DMACC0LLI to DMACC7LLI) contain a
word-aligned address of the next Linked List Item (LLI). If the LLI is 0, then the current LLI
is the last in the chain, and the DMA channel is disabled when all DMA transfers
associated with it are completed. Programming this register when the DMA channel is
enabled may have unpredictable side effects.
