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.

5.7.1 MUTEC PIN CONTROL(MUTEC)
Default = 0
0 - Two Mute control signals
1 - Single mute control signal on MUTEC1
Function:
Selects how the internal mute signals are routed to the MUTEC1 and MUTEC234 pins. When set to
‘0’, a logical AND of DAC pair 1 mute control signals are output on MUTEC1 and a logical AND of the
mute control signals of DAC pairs 2, 3, and 4 are output on MUTEC234. When set to ‘1’, a logical AND
of all DAC pair mute control signals is output on the MUTEC1 pin, MUTEC234 will remain static. For
more information on the use of the mute control function see the MUTEC1 and MUTEC234 pins in
section 3.11.
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.
5.7.3 SINGLE VOLUME CONTROL (SNGLVOL)
Default = 0
0 - Disabled
1 - Enabled
