MUTE PIN AS INPUT
The WM8768 can be muted externally by driving the MUTE pin high. When the MUTE pin is driven
low the device will never automute, although direct mutes can still be applied via the DMUTE or
MUTEALL registers.
The DZFM bits are used to decode the operation of a MUTE pin (decides which channels will be
affected by the logic level present on the MUTE pin). MPD (Mute Pin Decode) is used to enable the
DZFM operation. If MPD is set, the selection made by the DZFM bits will be ignored and all channels
will be muted when the pin is driven high.
Table 11 below describes which channels will be softmuted when the MUTE pin is driven high
depending on the MPD and DZFM bits.
