Description
Variable length transfer mode. In word mode, bits 12:0 of the first word is considered
as the transfer length.
000
Use LEN for transfer count
001
Transfer number of bytes/words commanded by first byte/word + 1
(transfers length byte/word, and then as many bytes/words as dictated by
length byte/word up to a maximum specified by LEN).
010
Transfer number of bytes/words commanded by first byte/word (transfers
length byte/word, and then as many bytes/words as dictated by length
byte/word – 1 up to a maximum specified by LEN).)
011
Transfer number of bytes/words commanded by first byte/word + 2
(transfers length byte/word, and then as many bytes/words as dictated by
length byte/word + 1 up to a maximum specified by LEN)
100
Transfer number of bytes/words commanded by first byte/word + 3
(transfers length byte/word, and then as many bytes/words as dictated by
length byte/word + 2 up to a maximum specified by LEN)

Alternative for using LEN as transfer count
The DMA channel transfer count.
This value is used as transfer count when VLEN=000 or VLEN=111 (fixed length
transfers) and as maximum allowable length when VLEN≠000 and VLEN≠111
(variable length transfers). The DMA channel counts in words when in WORDSIZE
mode, and otherwise in bytes.
The DMA channel transfer count.
This value is used as transfer count when VLEN=000 or VLEN=111 (fixed length

(variable length transfers). The DMA channel counts in words when in WORDSIZE
mode, and otherwise in bytes.
Selects whether each DMA transfer shall be 8-bit (0) or 16-bit (1).

Select DMA trigger
00000 No trigger (writing to DMAREQ is only trigger)
00001 The previous DMA channel finished
00010 Selects one of the triggers shown in Table 51. The trigger is selected in the
order shown in the table.
