C BUS SELECTION
Data transfers follow the usual I

C format; i.e. after the start condition (S), a 7-bit slave address is sent, fol-
lowed by an eight-bit 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 I

C bus decoder enables the automatic incre-
mentation mode in write mode.
