AT32 UC3A: ADC -> EBI -> DMA
Dalibor2000, You are correct. There is no DMA support for a peripheral device connected to EBI on a UC3A device. Note, however, that you can DMA data from say, an SPI connected...

Why two NOPs are used after "SSRF 16"?
Two NOPs were needed on early versions of the UC3 devices due to a hardware bug. This has been fixed in newer hardware revisions.

Interrupt handlers too slow?
You are going about this the wrong way. Just about any microcontroller or microprocessor available today is going to have trouble acomplishing this in an interrupt driven way....
