INPUT SHIFT REGISTER
The input shift register is 24 bits wide and consists of a read/write bit (R/ W ); a reserved bit (ZERO), which must always be set to 0; three
register select bits (REG2, REG1, REG0); three DAC address bits (A2, A1, A0); and 16 data bits (data). The register data is clocked in MSB
first on the SDIN pin.
