7.3.10.4 Configuring the Device for High-Speed I2C Mode

The device can be configured in high-speed I2C mode by providing an I2C frame with one of these codes: 0x09, 0x0B, 0x0D, or 0x0F.

After receiving one of these codes, the device sets the I2C_HIGH_SPEED bit in the SYSTEM_STATUS register and remains in high-speed I2C mode until a STOP condition is received in an I2C frame.
