6.4.1 AUTO-MUTE (AMUTE) BIT 7  
Function:  
When set to 1 (default) the Digital-to-Analog converter output will mute following the reception of 8192  
consecutive audio samples 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.  
When set to 0 this function is disabled  
6.4.2 AMUTEC = BMUTEC (MUTEC A=B) BIT 5  
Function:  
When set to 0 (default) the AMUTEC and BMUTEC pins operate independently.  
When set to 1, the individual controls for AMUTEC and BMUTEC are internally connected through an  
AND gate prior to the output pins. Therefore, the external AMUTEC and BMUTEC pins will go active only  
when the requirements for both AMUTEC and BMUTEC are valid.  
6.4.3 A CHANNEL MUTE (MUTE_A) BIT 4  
B CHANNEL MUTE (MUTE_B) BIT 3  
Function:  
When set to 1, the Digital-to-Analog converter output will mute. The quiescent voltage on the output will  
be retained. The muting function is effected, similar to attenuation changes, by the Soft and Zero Cross  
bits in the Volume and Mixing Control register. The corresponding MUTEC pin will go active following any  
ramping due to the soft and zero cross function.  
When set to 0 (default) this function is disabled.
