7 / 12 page  7/12 STV6688 Electrical Characteristics 2.5 I²C Bus Selection Data transfers follow the usual I²C format: after the Start condition (S), a 7-bit slave address is sent, followed by an 8-bit word 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 I²C Bus Decoder of the microcontroller provides the Automatic Incrementation mode in Write mode. String Format: Write Only mode (S = Start condition, P = Stop condition, A = Acknowledge) Input Signals Summary: (Write Mode) Input Signal: (Write Mode) Data Byte Figure 2: I²C Bus Timings t BUF t LOW t HIGH t f t r t HD,STA t HD,DAT t SU,DAT t SU,STA t SU,STO SDA SCL SDA (Start, Stop) S SLAVE ADDRESS: 94h A 00h A DATA A P Reg.Addr.
