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 :)
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 ?
