Volume Busy DAC Right
0x0 = Ready
0x1 = Busy - This indicates the channel has not reached its programmed volume/mute
level
Volume Busy DAC Left
0x0 = Ready
0x1 = Busy - This indicates the channel has not reached its programmed volume/mute
level
Reserved
Volume Ramp Enable
0x0 = Disables volume ramp. New volume settings will take immediate effect without
a ramp
0x1 = Enables volume ramp
This field affects DAC_VOL. The volume ramp effects both volume settings and mute.
When set to 1 a soft mute is enabled.
Exponential Volume Ramp Enable
0x0 = Linear ramp over top 4 volume octaves
0x1 = Exponential ramp over full volume range
This bit only takes effect if VOL_RAMP_EN is 1.
Reserved
DAC Right Mute
0x0 = Unmute
0x1 = Muted
If VOL_RAMP_EN = 1, this is a soft mute.
DAC Left Mute
0x0 = Unmute
0x1 = Muted
If VOL_RAMP_EN = 1, this is a soft mute.
ADC High Pass Filter Freeze
0x0 = Normal operation
0x1 = Freeze the ADC high-pass filter offset register. The offset will continue to be
subtracted from the ADC data stream.
ADC High Pass Filter Bypass
0x0 = Normal operation
0x1 = Bypassed and offset not updated
