Mute Control
The Mute Control pins go active during power-up initialization, muting, or if the MCLK-to-LRCK ratio is in-
correct. These pins are intended to be used as control for external mute circuits to prevent the clicks and
pops that can occur in any single-ended, single-supply system. The MUTEC output pins are high impedance
at the time of reset. The external mute circuitry needs to be self biased into an active state in order to be
muted during reset. Once reset has been released, the MUTEC pins are active high in hardware mode and
the active state is set by the MUTEC+/- register in software mode (see
