29 DMA1PRESA
Set to write skipped bytes back on next DMA1WR triggered write. Use this together with DMA1SKIP to enable in-place con-
versions with CRYPTO
28 DMA0PRESA
Set to write skipped bytes back on next DMA0WR triggered write. Use this together with DMA0SKIP to enable in-place con-
versions with CRYPTO
27:26 DMA1SKIP
Set to number of bytes to exclude from data received by next DMA1RD insruction
25:24 DMA0SKIP
Set to number of bytes to exclude from data received by next DMA0RD insruction
23:22 Reserved
21:20 BLOCKSIZE
Defines the width of blocks processed in each iteration of a sequence running on a dataset (see related note in
31.4.3 Repeated Sequence)

19:14 Reserved
13:0 LENGTHA
This field sets the number of bytes to be handled during the repeated sequence. Set it to the exact number of bytes. If the
number is not a multiple of BLOCKSIZE, the last data block is zero-padded. Format is unsigned integer.
