Hello all,

I am trying to stop a DMA transfer at a specific moment using the trq pin.

As nowhere in the documentation a timing diagram is shown with the trq input, i've used a clock on the trq signal until the nrq is generated.

But this creates some problems:

- when i use the trq as mentioned above i have 2 extra transfers than i should ( i am using an analyzer on the drq line)

- without the trq i do not have this behaviour


Is there any changes that the trq might force more transfers?

Hi @Mihai 


Please have a look at this thread -

We are investigating this issue internally regarding the trq signal and will update once we find the root cause. 


Best regards,
