Hello, About eDMA module.DMA_TCDn_WORD_2_MLOOP.jpg

There is the MLOFF field in the DMA_TCDn_WORD_2_MLOOP register. But I can't find the MLOFF in the pseudo-code steps of channel processing. Bellow is the ending minor loop.TIM截图20190617171039.jpg

How it affect the processing when it is enable ?

Hi,

MLOFF will create minor loop offset.

When minor loop offsets are enabled, the minor loop offset (MLOFF) is added to the final source address (SADDR), or the final destination address (DADDR), or both prior to the addresses being written back into the TCD.

regards,

Peter
