PRODUCTION DATA.
DRDY is an output that is driven low when new conversion data are ready, as shown in Figure 51. When reading data in continuous mode, the read operation must be completed before four CLK periods before the next falling DRDY goes low again, or the data are overwritten with new conversion data. When reading data in command mode, the read operation can overlap the occurrence of the next DRDY without data corruption.
DRDY resets high on the first falling edge of SCLK. Figure 51 and Figure 52 show the function of DRDY with and without data readback, respectively.
If data are not retrieved (no SCLK provided), DRDY pulses high for four fCLK periods during the update time, as shown in Figure 52.
DRDY remains active when CS is high.
