Figure 12-121 shows the I2C data transfer format in HS mode.
Each multicontroller I2C controller can also operate in HS mode. In this case, after the S condition, the module, which is in F/S mode, writes the controller code address (0x00001XXX, where XXX is the variable portion of the controller code) on the bus. No device connected on the same bus acknowledges this address. The module switches the clock to the HS clock and after an Sr condition, and sends the target address and the data, as shown in Figure 12-121.
