STV6411A
I²C BUS SELECTION
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). A 8-bit subadress is sent to select a register, fol-
lowed by a 8-bit data word to put in it.
The IC's I2C bus decoder permits the automatic incrementation mode in write mode.
