FIGURE 1-15:
Read Command and Data on I
C bus. Note the RDY bit in 4th byte is “0”. This means
the conversion data just read is the latest conversion data. The RDY bit becomes “1” in the 5th byte
(repeated byte). This means the device is now in the process of new conversion and the new result is not
ready yet.
