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. After the RDY bit is read out at the 4th byte, the
RDY bit becomes “1” in the 5th 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.
