Hi all,
I have 2 question about EDMA3.
Q1)
I'd like to trigger EDMA with high precision time interval.
For example, if I want to trigger EDMA with an internal DMTIMER at a cycle of 60 us and start a DMA transfer,
how long will it take for DMA transfer to start?(60usec + clock cycle time?)
Should I consider only the deviation of DMTIMER's clock souce?
Or is there a delay from DMTIMER trigger to DMA transfer start?
If there is a delay time, I want to know the time.
Q2)
If I set DMTIMER to E0(event number), can I realize the above trigger at 60 usec?
Since E 0 is high priority, I think that E0 will be sent to the event queue
if a trigger event enters at the same time,
but will E0 be kept waiting if an event of E0 comes in immediately after entering the event of E1?
I would like to build a system that always triggers DMA with a cycle of 60 us.
Best regards,
Sasaki
