Table 21 Mute Modes
ANRES is the reset to the switched capacitor filter.
ANMUTE is an analogue muting signal gating the analogue signal at the output (after the
SC filter)
AUTOMUTE is asserted when both the IZD register bit is asserted and the input audio data has
been zero on both left and right channels for 1024 input samples. The first non-zero sample de-
asserts.
Applying a logic low to MUTEB or setting MUT in Reg2 causes the gain registers to ramp to zero.
When a logic high is applied, the gain ramps slowly back up to the value held in the appropriate
attenuation register (AL or AR). The ramp rate = 128/fs s/0.5dB step.
If SOFTMUTE is set or
MUTEB=0 then GAINL and
GAINR are overridden to 00
