7.2.5 I2C Interface Protocol

The driver supports command/data write to addressed slaves on the bus. Before any data is transmitted on

the I2C Interface, the device which should respond is addressed first. The default slave address is 0111100b

and the three times I2C address could be OTP programing.

The sequence is initiated with a START condition (S) from the I2C Interface master, which is followed by the

slave address. All slaves with the corresponding address acknowledge in parallel, all the others will ignore the

I2C Interface transfer. After acknowledgement, one or more command or data words are followed and define

the status of the addressed slaves.

Only the addressed slave makes the acknowledgement after each byte. At the end of the transmission the

bus master issues a STOP condition (P). If no acknowledge is generated by the master after a byte, the driver

stops transferring data to the master. The register write/ read transference sequence are described as

follows.
