The more recent IBM power processors have an embedded I2C controller that is accessible by software via the XSCOM address space. Each instance of the I2C controller is capable of controlling multiple I2C buses (one at a time). Prior to beginning a transaction on an I2C bus, the bus must be selected by writing the port number associated with the bus into the PORT_NUM field of the MODE register. Once an I2C bus is selected, the status of the bus can be determined by reading the Status and Extended Status registers. I2C bus transactions can be started by writing a command to the Command register and reading/writing data from/to the FIFO register. Not supported : . 10 bit I2C addresses . Multimaster .
