The output register and the contents of the configuration register can be read from the ADS1000-Q1. To read data, address the ADS1000-Q1 for reading, and read three bytes from the device. The first two bytes are the output register contents; the third byte is the configuration register contents.

Three bytes do not always have to read from the ADS1000-Q1. If only the contents of the output register are needed, read only two bytes.

Reading more than three bytes from the ADS1000-Q1 has no effect. All bytes beginning with the fourth byte are FFh. Figure 7-3 shows a timing diagram of an ADS1000-Q1 read operation.
