DAC2R Digital Volume
0000 0000 = -100dB
0000 0001 = -99.5dB
0000 0010 = -99dB
…0.5dB steps
1100 1000 = 0dB
…0.5dB steps
1101 1111 = +11.5dB
111X XXXX = +12dB
DAC2R Digital Volume Update
0 = Latch DAC2R_VOL[7:0] into Register Map but do not update volume
1 = Latch DAC2R_VOL[7:0] into Register Map and update left and right channels simultaneously
Device Global Enable
0 = ADC, DAC and PGA ramp control circuitry disabled
1 = ADC, DAC and PGA ramp control circuitry enabled
DAC2 Configuration Control
0 = DAC2 settings independent of DAC1
