None. I don't think CPU can access DSKDAT or DSKDATR. It probably works like AUDxDAT, Paula ignores all CPU accesses if channel's DMA is enabled. Disk part probably don't implement extra logic(?) needed to support CPU accesses because it would make no sense, there is no flag that tells when write buffer needs new data.
