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

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.
