If desired, poll the DRDY bit in the STATUS word instead of polling the DRDY pin. In software poll mode, read the STATUS0 byte and poll the DRDY bit. If the bit is high, then conversion data are new from the last data read operation. If the bit is low, conversion data are not new from the last data read operation. In this case, the previous conversion data are returned. In order to avoid missing conversion data in continuos conversion mode, poll the bit at least as often as the period of the data rate.
