Use the RDATA command to read conversion data when not in read data continuous mode. Issue this command after DRDY goes low to read the conversion result (in stop read data continuous mode). There are no SCLK rate restrictions for this command, and there is no wait time needed for subsequent commands or data retrieval SCLKs. To use the RDATA command, the device must be actively converting (the START pin must be held high or the START command must be issued). When reading data with the RDATA command, the read operation can overlap the next DRDY occurrence without data corruption. RDATA can be sent multiple times after new data are available, thus supporting multiple data readback. Figure 42 illustrates the recommended way to use the RDATA command. RDATA is best suited for systems where register settings must be read or the user does not have precise control over timing. Reading data using the RDATA command is recommended to avoid data corruption when the DRDY signal is not monitored.
