Yes, that's somewhat similar to I2C, but the datasheets shows that the data bus is 12-bit wide, while I2C's is 1-bit only. I even wonder how they can call that a serial bus. Anyway, that's what made me say it's not an I2C chip (plus the fact that searching the data sheet for I2C or SMBus returned nothing). > Sorry that I wasted so much time of you, No problem.
