The RREG is used to read the device registers. The binary format of the command word is 101a aaaa annn nnnn, where a aaaa a is the binary address of the register to begin reading and nnn nnnn is the unsigned binary number of consecutive registers to read minus one. There are two cases for reading registers on the ADS130B02-Q1. When reading a single register (nnn nnnn = 000 0000b), the device outputs the register contents in the command response word of the following frame. If multiple registers are read using a single command (nnn nnnn > 000 0000b), the device outputs the requested register data sequentially in order of addresses.
