List Item (LLI) in
system memory at the
end of the block
transfer with
the done bit
set.Software can poll
the LLI CTL0.DONE bit
to see when a block
transfer is complete.
The LLI CTL0.DONE bit
should be cleared
when the linked lists
are set up in memory
prior to enabling the
channel.LLI accesses
are always 32-bit
accesses (Hsize = 2)
aligned to 32-bit
boundaries and cannot
be changed or
programmed to
anything other
than 32-bit.

Block length
(BLOCK_TS)
When the DMAC is the
flow controller, the
user writes this field
before the channel is
enabled in order to
indicate the block size.
The number
programmed into
BLOCK_TS indicates
the total number of
single transactions to
perform for every block
transfer.
A single transaction is
mapped to a single
AMBA beat.
Width: The width of
the single transaction
is determined by
