Configuration Register 2 Field Descriptions Bit Field Type Reset Description 7 DRDY R 0h Conversion result ready flag. This bit flags if a new conversion result is ready. This bit is reset when conversion data are read. 0 : No new conversion result available (default) 1 : New conversion ...
In that case, the samples are cleared from the device each time new data are generated so the DRDY flag for each channel in the STATUS register is cleared with each read. However, both slots of the FIFO are full if a sample is missed or if data are not read for a period of time....
