5 I²C BUS SPECIFICATIONS
Data transfers follow the usual I²C format: after the start condition (S), a 7-bit slave address is sent, fol-
lowed by an eighth bit which is a data direction bit (W). An 8-bit sub-address is sent to select a register, fol-
lowed 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.
