While working with this new CQD220A document I found an error where "W6-5" is listed twice, and "W6-3" is skipped. Here is the original section:
--------------------------------------------------------------------------
W6-1 OUT Adaptive DMA enabled (F)
W6-2 OUT Adaptive DMA Dwell Time enabled (F)

W6-4 W6-5
IN IN 0.8-ms DMA dwell time
OUT IN 1.6-ms DMA dwell time
IN OUT 3.2-ms DMA dwell time
OUT OUT 6.4-ms DMA dwell time
W6-5 OUT Block mode DMA enabled (F)
--------------------------------------------------------------------------
I expect it should be something like this:
--------------------------------------------------------------------------
W6-1 OUT Adaptive DMA enabled (F)
W6-2 OUT Adaptive DMA Dwell Time enabled (F)

W6-3 W6-4
IN IN 0.8-ms DMA dwell time
OUT IN 1.6-ms DMA dwell time
IN OUT 3.2-ms DMA dwell time
OUT OUT 6.4-ms DMA dwell time
W6-5 OUT Block mode DMA enabled (F)
--------------------------------------------------------------------------

But I am not sure. My card had a jumper installed on W6-3, and I am thinking it set the DMA dwell time to 3.2ms. Removing it, change to 6.4ms, seemed to help with a crashing problem.
