These are accessed by programming #define PTR 0x00 /* Indexed register set pointer register */ /* NOTE: The CHANNELNUM and ADDRESS words can */ /* be modified independently of each other. */ #define DATA 0x04 /* Indexed register set data register */ Basically, one writes the register address to PTR, and then read or write to DATA. On the Audigy2 there is a similar setup for 0x20 and 0x24. I suspect that this is used to program the p16v chip. Had anyone looked into those registers, and tried to guess what they do ? I might give it a go, once I finish the Audigy LS driver.
