D1–D0
(
R/W 00 00: Left and right channels have independent volume control.
1)
01: Left-channel volume control is the programmed value of right-channel volume control.
10: Right-channel volume control is the programmed value of left-channel volume control.
11: Same as 00
(1) When DRC is enabled, left and right channel volume controls are always independent. Program bits D1–D0 to 00.
