7.5 Filter Control (Address 05h)
7.5.1 Interpolation Filter Select (FILT_SEL)
Function:
When set to 0 (default), the Interpolation Filter has a fast roll-off.
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 27 to 50.
7.6 Invert Control (Address 06h)
Non-TDM Mode (DIF  0001, see Section 7.3.1)
TDM Mode (DIF  0001, see Section 7.3.1)
7.6.1 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.
7.7 Group Control (Address 07h)
7.7.1 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 in-
formation on the use of the mute control function, see the MUTEC1 and MUTEC234 pins in Section 4.11.
