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.
