Figure 2 shows typical waveforms for the circuit on the Note that in this example, the 8-bit hexadecimal address front page. In this example, the master transmits address format (with R/W = 0) is used. 7-bit addresses are also 0x34 while the slave is configured to respond to address commonly found in I2C device documentation. Make sure 0x36. The resistive dividers at the XORL and XORH pins are to use the correct format when calculating the address configured to generate an address translation byte of 0x02. translation byte. Table 1 shows examples of both formats.
