SBASAD2 November 2021 ADS130B04-Q1
Read a single register from the device by specifying nnn nnnn as zero in the RREG command word. As with all SPI commands on the ADS130B04-Q1, the response occurs on the output in the frame following the command. Instead of a unique acknowledgment word, the response word is the contents of the register whose address is specified in the command word. Figure 8-19 shows an example of reading a single register.
