STM32F0 - How to abort a DMA transfer?

Hi!

I was wondering what is the correct way to abort an ongoing DMA transfer?

I have a situation where it seems like there was an incoming DMA request while I had the DMA disabled.

I disable all channel triggers and when I re-enable the DMA channel I get a single transfer immediately.

Is there a way to clear this 'pending' DMA request?

Timer triggered DMA? Toggle the bit which enables it in DIER.
