I2C BUS SPECIFICATIONS Data transfers follow the usual I2C format: after the start condition (S), a 7-bit slave address is sent, followed by an eight-bit which is a data direction bit (W). An 8-bit sub-address is sent to select a register, followed by an 8-bit data word to be included in the register. The IC's I2C bus decoder permits the automatic incrementation mode in write mode. The circuit operates up to clock frequencies of 400 kHz.
