Hi all,
I was wondering if it is possible to enable source transaction complete interrupt for the GPDMA module (XMC4400), if the source is a peripheral and destination is memory. Memory transfers don't have transaction "levels" but there's nothing that seems to prohibit source to fetch data through transactions and then buffer them in a FIFO to be sent out as AHB transfers to memory.
Best regards,
Andrey

Hi,
You can do but the event will signal that the last data has been taken from source (and stored in the FIFO) but it does not mean that is available in the destination.
