Hello, Please can you forward my question to ALI/ULI? (maybe strip my name, so it seems it comes from you directly :) Please take a look to your datasheet first If it is written there or not, but I think it is not, because simply commands belong usually to command register :) Question: We are implementing the driver for M1563 SMBus host and we ran into some trouble. We have implemented in our SMBUS driver the "continous byte mode" SMB_CMD 001, in all other chipsets it seems command belong to CMD register, but this mode accepts command in DAT0 register. Is this undocumented feature or a "silicon" bug? Can you tell us if this is true also for M1535, M1541 and M1543C ? Thanks Regards Rudolf
