CS4364

When set to 1, the Interpolation Filter has a slow roll off.

The specifications for each filter can be found in the Analog characteristics table, and response plots can

be found in Figures 24 to 47.

5.6

Invert Control (address 06h)

5.6.1

Invert Signal Polarity (INV_xx)

Function:

When set to 1, this bit inverts the signal polarity of channel xx.

When set to 0 (default), this function is disabled.

5.7

Group Control (address 07h)

5.7.1

Mute Pin Control (MUTEC1, MUTEC0)

Default = 00

00 - Six mute control signals

01, 10 - One mute control signal

11 - Three mute control signals

Function:

Selects how the internal mute control signals are routed to the MUTEC1 through MUTEC6 pins. When

set to ‘00’, there is one mute control signal for each channel: AOUT1A on MUTEC1, AOUT1B on

MUTEC2, etc. When set to ‘01’ or ‘10’, there is a single mute control signal on the MUTEC1 pin. When

set to ‘11’, there are three mute control signals, one for each stereo pair: AOUT1A and AOUT1B on

MUTEC1, AOUT2A and AOUT2B on MUTEC2, and AOUT3A and AOUT3B on MUTEC3.

5.7.2

Channel A Volume = Channel B Volume (Px_A=B)

Default = 0

0 - Disabled

1 - Enabled

Function:

The AOUTAx and AOUTBx volume levels are independently controlled by the A and the B Channel Vol-

ume Control Bytes when this function is disabled. The volume on both AOUTAx and AOUTBx are deter-

mined by the A Channel Attenuation and Volume Control Bytes (per A-B pair), and the B Channel Bytes

are ignored when this function is enabled.
