VALUE
00
BIT
DESCRIPTION
D7–D6
Left-DAC Output Switching Control
00: Left-DAC output selects DAC_L1 path.
01: Left-DAC output selects DAC_L3 path to left line output driver.
10: Left-DAC output selects DAC_L2 path to left high-power output drivers.
11: Reserved. Do not write this sequence to these register bits.
Right-DAC Output Switching Control
00: Right-DAC output selects DAC_R1 path.
01: Right-DAC output selects DAC_R3 path to right line output driver.
10: Right-DAC output selects DAC_R2 path to right high-power output drivers.
11: Reserved. Do not write this sequence to these register bits.
Reserved. Write only zeros to these bits.
DAC Digital Volume Control Functionality
00: Left- and right-DAC channels have independent volume controls.
01: Left-DAC volume follows the right-channel control register.
10: Right-DAC volume follows the left-channel control register.
11: Left- and right-DAC channels have independent volume controls (same as 00).

1011: Driver power-on time = 4 s
1100–1111: Reserved. Do not write these sequences to these register bits.
Driver Ramp-Up Step Timing Control
00: Driver ramp-up step time = 0 ms
01: Driver ramp-up step time = 1 ms
10: Driver ramp-up step time = 2 ms
11: Driver ramp-up step time = 4 ms
Weak Output Common-Mode Voltage Control
0: Weakly driven output common-mode voltage is generated from resistor divider off the AVDD supply.
1: Weakly driven output common-mode voltage is generated from band-gap reference.
Reserved. Write only zero to this register bit.
