About PPI priorities

[Paul]

We all know that PPI can have the same event to trigger other tasks. But I couldn't find any official document explaining the priorities/timing of those tasks linked to the same events.

My understanding and test are showing the lower PPI channel numbers have the high priorities which will happen first.

I just wanted an official answer to confirm this finding is true.

Thanks

I agree. If as you have described in the previous response, the PPI happens in the same clock cycle, then it is the task priority related. Official document only describes START and STOP priorities.

Based on my test CAPTURE TASK happens first then the TIMER gets cleared, which is most people would want. If it is always consistent in XLR2 silicon level, then it is great, and should always keep that way :-D.

Thanks

Yes, this is as designed and hence expected to be consistent on the XLR2 chip revision. I agree that this information should be in the RM, so I'll create a task internally to add this information in a future version.

For now, I'd as usual be happy if you could accept my reply above as an answer, since I believe that answers the original question. :-)
