The I2C bus can run in standard mode (100 kbps), fast mode (400 kbps), fast mode plus (1 Mbps) or high-speed mode (3.4 Mbps, if the correct system clock frequency is set and there is appropriate pull strength on SCL and SDA). The selected mode should match the speed of the other I2C devices on the bus.
