Filter Control (Address 04h)
Auto-Mute (AMUTE)
Default = 1
0 - Disabled
1 - Enabled
Function:
The Digital-to-Analog converter output will mute following the reception of 8192 consecutive audio sam-
ples of static 0 or -1. A single sample of non-static data will release the mute. Detection and muting is
done independently for each channel. The quiescent voltage on the output will be retained and the Mute
Control pin will go active during the mute period. The muting function is affected, similar to volume control
changes, by the Soft and Zero Cross bits in the Mode Control 3 register.
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
Description.
Interpolation Filter Select (FILT_SEL)
Default = 0
0 - Fast roll-off
1 - Slow roll-off
Function:
This Function allows the user to select whether the interpolation filter has a fast or slow roll off. For filter
characteristics please see Section 1.
De-Emphasis Control (DEM)
Default = 00
00 - Disabled
01 - 44.1 kHz
10 - 48 kHz
