FIGURE 1-15: Read Command and Data on I

C bus. Note the RDY bit in 3rd byte is “0”. This means
the conversion data just read is the latest conversion data. After the RDY
bit is read out at the 3rd byte, the
RDY
bit becomes now “1” in the 4th byte (repeated byte). This means the device is now in the process of a
new conversion and the latest conversion result is not ready yet.
