7.5.3.7 RDATA: Read Conversion Data Command

The RDATA command (Figure 7-25) is useful to re-read data within the same conversion period or to read data interrupted by a read register command. In both cases, DRDY is high because DRDY is driven high on the first SCLK of the previous operation. If DRDY is high, the first output byte is zero followed by data. If low, the first output byte is byte 1 of the conversion data, which is restarted for output byte 2.
