MUTE MODES
The WM8580 has individual mutes for each of the three DAC channels. Setting DMUTE for a
channel will apply a ‘soft-mute’ to the input of the digital filters for that channel. DMUTE[0] mutes
DAC1 channel, DMUTE[1] mutes DAC2 channel and DMUTE[2] mutes DAC3 channel. Setting the
MUTEALL register bit will apply a ‘soft-mute’ to the input of all the DAC digital filters. A soft-mute
allows the user to control the analog output of the DAC such that the output waveform is looks like
that shown in Figure 23.
The MUTE pin can also be used to apply soft-mute to the DAC selected by the DZFM register bits.
However, if the MPDENB register bit is set, the MUTE pin will activate a soft-mute for all DACs.

DAC channel master soft mute.
Mutes all DAC channels:
0 = disable soft-mute on all
DACs.
1 = enable soft-mute on all
DACs.

0 = MUTE activates soft-mute
on DAC selected by DZFM
1 = MUTE activates softmute
on all DACs
