7.7.4 MUTE ADC SERIAL PORT (MUTE ADC_SP)
Default = 0
0 - Disabled

7.8.1 INDEPENDENT CHANNEL MUTE (AOUTX_MUTE)
Default = 0
0 - Disabled
1 - Enabled
Function:
The respective Digital-to-Analog converter outputs of the CS42436 will mute when enabled. The qui-
escent voltage on the outputs will be retained. The muting function is affected by the DAC Soft and
Zero Cross bits (DAC_SZC[1:0]).

7.9.1 VOLUME CONTROL (AOUTX_VOL[7:0])
Default = 00h
Function:
The AOUTx Volume Control registers allow independent setting of the signal levels in 0.5 dB incre-
ments from 0 dB to -127.5 dB. Volume settings are decoded as shown in Table 8. The volume chang-
es are implemented as dictated by the Soft and Zero Cross bits (DAC_SZC[1:0]). All volume settings
less than -127.5 dB are equivalent to enabling the AOUTx_MUTE bit for the given channel.
