Issue this command after DRDY goes low to read the conversion result (in Stop Read Data Continuous mode). There is no restriction on the SCLK rate for this command, and there is no wait time needed for the subsequent commands or data retrieval SCLKs. To retrieve data from the device after RDATA command is issued, make sure either the START pin is high or the START command is issued. When reading data with the RDATA command, the read operation can overlap the occurrence of the next DRDY without data corruption. Figure 53 shows the recommended way to use the RDATA command. RDATA is best suited for ECG- and EEG-type systems where register setting must be read or changed often between conversion cycles.
