The AD8153 write process is shown in Figure 32. The SCL
signal is shown along with a general write operation and a
specific example. In the example, data 0x92 is written to
Address 0x6D of an AD8153 part with a part address of 0x4B.
The part address is seven bits wide and is composed of the
AD8153 static upper four bits (b1001) and the pin
programmable lower three bits (I2C_ADDR[2:0]). In this
example, the I2C_ADDR bits are set to b011. In Figure 32, the
corresponding step number is visible in the circle under the
waveform. The SCL line is driven by the I
by the AD8153 slave. As for the SDA line, the data in the shaded
polygons is driven by the AD8153, whereas the data in the non-
shaded polygons is driven by the I

It is important to note that the SDA line only changes when the
SCL line is low, except for the case of sending a start, stop, or
repeated start condition, Step 1 and Step 9 in this case.
