The RREG command reads register data. The command is comprised of two bytes followed by output of the designated number of register bytes. The ADC auto-increments the address up to the number of registers specified in byte 2 of the command. The incrementing address does not wrap. The first byte of the command is the opcode added to the register starting address, and the second byte is the number of registers to read minus one.
Figure 8-26 shows an example of a three-register read operation starting at register address 01h. The first register data appears on DOUT at the 16th falling edge of SCLK. The data are latched on the rising edge of SCLK.
