4.1.14 INDEPENDENT VOLUME CONTROL ENABLE (INDVC)
Default = 0
0 - Disabled
1 - Enabled
Function:
When this function is disabled, the AIN_L and AIN_R volume levels are controlled by the Left and Right
Volume Control registers and the Independent Analog Gain Control registers are ignored.
When this function is enabled, the volume levels are determined by both the Volume Control registers and
the Independent Analog Gain Control registers.
4.1.15 LEFT CHANNEL VOLUME = RIGHT CHANNEL VOLUME (L=R)
Default = 0
0 - Disabled
1 - Enabled
Function:
When this function is disabled, the left channel volume is determined by the left channel volume control
register and right channel volume is determined by the right channel volume control register.
When enabled, the left and right channel volumes are determined by the left channel volume control reg-
ister and the right channel volume control register is ignored.
4.1.16 HIGH-PASS FILTER FREEZE (HPFREEZE)
Default = 0
0 - Frozen
1 - Enabled
Function:
The high-pass filter works by continuously subtracting a measure of the dc offset from the output of the
decimation filter. If the HPFREEZE bit is taken low during normal operation, the current value of the dc
offset is frozen and this dc offset will continue to be subtracted from the conversion result.
