comedi driver pcimio configuration programmed IO

Hello,

I use comedi for my PCI 6229-Card (which is supported by ni_pcimio) and apparently it works fine (so far). However, the comedi documentation contains no information about how I can configure ni_pcimio.

I really need to know how can I change the data transfer mechanism from DMA to programed IO in order to reduce the latency.

Any help would be much appreciated.
