6.17.2 DAC1-4 Attenuation
Sets the mode of attenuation used for the DAC1-4 path.
Note: See Section 4.6.6 Volume Control for details regarding the attenuation modes.
6.17.3 Mute Low-latency Path
Mutes the low-latency path.
6.17.4 Mute DACx
Mutes the DACx signal.
6.18 DAC Control 4 (Address 15h)
6.18.1 VQ Ramp
Ramps common mode voltage “VQ” down to ground. This bit needs to be set before asserting reset pin.
6.18.2 TPS Mode 1 Gain Select
When “TPS MODE” bit in the "TPS Control" register is set to 1, this bit sets the gain of the signal through
the TPS path.
6.18.3 Power Down DACx
Powers down the DACx path.
