This address consists of 7 bits. The left 1 bit (the foot bit) is fixed “0”. The stop condition (P) is needed to finish the data transferred. But the re-send starting condition (Sr) enables to transfer the data without STOP (P). Figure 11. DATA transmit 1.5 Data format The format is following. Figure 12. Data format Table 1. for WRITE format Slave address A0 to A2 Each bit can be defined by the input levels of pins A0 to A3. A3 to A6 These 4 bits are fixed. R/W “0” Write Data D0 to D7 Write “1” to D0 makes Q0 pin High-impedance. And write “0” makes Q0 pin LOW. D[1:7] and Q[1:7] are same as D0 and Q0.
