Master mute. A 1-bit value to enable the digital mute for the master. When
this bit is logic 0: no soft mute of master. When this bit is logic 1: soft mute of
master. Default value 1.
default value 00
Channel 2 mute. A 1-bit value to enable the digital mute for channel 2. After
enabling the mixer, bit MT2 must be set to logic 0. When this bit is logic 0: no
soft mute of channel 2. When this bit is logic 1: soft mute of channel 2. Default
value 1 (meaning that channel 2 is always muted, even when the mixer is
enabled).
De-emphasis. A 3-bit value to enable the digital de-emphasis filter for
channel 2. Default value 000, see Table 45.
default value 0000
Channel 1 mute. A 1-bit value to enable the digital mute for channel 1. When
this bit is logic 0: no soft mute of channel 1. When this bit is logic 1: soft mute
of channel 1. Default value 0.
De-emphasis. A 3-bit value to enable the digital de-emphasis filter for
channel 1. Default value 000, see Table 45.
